Memory Module Types

2009-02-25T12:46:00.000-08:00

Memory Module Types

30 Pin SIMM

The 30 Pin SIMM was the first generation of the SIMM memory family.

They are typically found in older Intel 286 and 386 desktop computer systems. They come in both 8 bit and 9 bit (parity) configurations, with memory ranges of 256K to 8 megabyte, 60ns to 80ns and are 5 Volts only. The DRAM types supported are mostly Page Mode and Nibble Mode DRAM which comes in both DIP, PLCC and SOJ packages.

72 Pin SIMM

The 72 Pin SIMM was the second generation of the SIMM family.

They are typically found in the Intel 486, 486DX, 586 and some early Pentium desktop computer systems. They come in both 32 bit and 36 bit (parity) configurations, with memory ranges of 4, 8, 16 and 32 megabytes. These were normally produced in two voltage, 5V and 3.3V, and theirs speeds ranged from 60ns to 70ns.

168 Pin DIMM

The 168 PIN DIMM is what is found in most desktop computers today.

Early on there were three memory types offered in the 168 Pin DIMM form factor, FPM, EDO and Synchronous DRAM (SDRAM). Their configurations include 64bit, 72bit and 80Bit, ECC and Non-ECC, and memory sizes included 16, 32, 64, 128, 256, 512 and 1,024 megabytes. Available voltages included 3.3v and 5v for FPM and EDO, and 3.3v for SDRAM.

72 Pin SODIMM

72 Pin SODIMM's are typically found in Pentium II Laptop computer. They come in 64 bit configurations, with memory ranges of 8, 16 and 32 megabyte. These modules are designed around lower power consumption and only one voltage is offered, FPM and EDO at 3.3v. FPM and EDO are the standard DRAM types offered and the packaging is referred to as SOJ.

144 Pin SODIMM

144 Pin SODIMM's are typically used in PC 66 and PC 100 SDRAM Laptop compatible computers. It comes in both 64 bit and 72bit ECC versions and the memory ranges were 16 to 256 megabyte. The SDRAM chips used in 144 Pin SODIMM's are typically SDRAM in the form of TSOP packaging and available in 3.3v only.

100 Pin DIMM

100 Pin DIMMs are primarily used in printers. It comes in both 64 bit and 72bit ECC configurations, and is available in memory ranges of 16 to 128 megabytes. The SDRAM chips used on the 100 Pin DIMM are typically SDRAM in TSOP packaging. Both FPM and EDO were/are used in 100 Pin DIMM.

184 Pin RIMM

The 184 pin RIMM is used on motherboards using the latest Intel i820/i840 chipsets and is referred to as Rambus. The 184 pin RIMM module comes in both 16bit and 18bit ECC configurations, operating frequencies of 600MHz, 700MHz and 800 MHz and are available with memory ranges of 64 through 512 megabytes. The Rambus packaging is referred to as the Ball Grid Array (BGA) form factor. The Rambus modules only require 2.5 volts. There is a 1 GHz Rambus chip under development that was slated for release in 2001.

184 Pin DIMM

DDR SDRAM is the newest of the memory types under development that will be available in the 184 Pin DIMM form factor. The principle difference between conventional SDRAM and DDR SDRAM is its ability to read/write data on both edges of a clock, therefore resulting in faster data transfer. DDR SDRAM will be available in two frequencies, 200Mhz and 266Mhz, and operational voltage is 2.5v. There is speculation (these have not been released to manufacturing as of this writing) that these modules will be available in both 64 bit and 72bit ECC configurations, with memory ranges of 64 megabytes through to 1 gigabyte. The DDR SDRAM chips used are of the TSOP package.

200 Pin SODIMM

The 200 Pin SODIMM module comes in both 64 bit and 72bit ECC configurations, with memory ranges of 64 megabyte through 512 megabyte. DDR SODIMM modules are slated for use in next-generation DDR Laptop applications. The DDR SDRAM chips used on the 200 DIMM are typically in TSOP packaging.

4GB PC3-8500 204 pin DDR3 SODIMM

2008-11-21T09:16:00.000-08:00

4GB PC3-8500 (1066Mhz) 204 pin DDR3 SODIMM (CKS)

4GB DDR3 204-pin laptop memory for newer laptop computers based on this new memory technology.To use ddr3 memory, your system must have both a 204-pin sodimm slot and a chipset that supports ddr3 memory. A ddr3 sodimm will not fit into ddr2 or ddr memory sockets.sodimms are smaller and thinner than regular dimms, and the 204-pin sodimm pcbs are always ~2.6 inches long and are usually around 1.75 inches high . They consist of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The number of memory components on a 204-pin sodimm's printed circuit board (pcb) can vary, but the pcb will always have 102 pins on the front and the back both, for a total of 204 pins.

Memory cards

2008-11-20T10:49:00.000-08:00

A memory card or flash memory card is a solid-state electronic flash memory data storage device used with digital cameras, handheld and Mobile computers, telephones, music players, video game consoles, and other electronics. They offer high re-record-ability, power-free storage, small form factor, and rugged environmental specifications. There are also non-solid-state memory cards that do not use flash memory, and there are different types of flash memory.

There are many different types of memory cards and jobs they are used for. Some common places include in digital cameras, game consoles, cell phones, and industrial applications. PC card (PCMCIA) were among first commercial memory card formats to come out in the 1990s, but are now only mainly used in industrial applications and for I/O jobs (using types I/II/III), as a connection standard for devices (such as a modem).
From the late 1990s into the early 2000s a host of new formats appeared, including SD/MMC, Memory Stick, xD-Picture Card, and a number of variants and smaller cards. The desire for ultra-small cards for cell-phones, PDAs, and compact digital cameras drove a trend toward smaller cards that left the previous generation of "compact" cards looking big. In digital cameras SmartMedia and CompactFlash had been very successful, in 2001 SM alone captured 50% of the digital camera market and CF had a strangle hold on professional digital cameras.

Nowadays, most new PCs have built-in slots for a variety of memory cards; Memory Stick, CompactFlash, SD, etc. Some digital gadgets support more than one memory card to ensure compatibility.

DDR memory

2008-11-17T09:04:00.000-08:00

DDR memory ( Double Data Rate memory), is a new high performance type of memory that runs at twice the speed of normal SDRAM. This DDR SDRAM is ideally suited to the latest high performance processors to increase overall system speed. The faster the memory, the quicker DDR Memory PC 3200, PC2700 and PC2100 , PC2100 SO-DIMM - 184 pin, 200 pin instructions can be passed to the processor. DDR memory provides roughly a 15% boost in performance compared to regular SDRAM. With DDR memory now in the affordable price range, and motherboard manufacturers phasing out SDRAM on nearly every new board, it looks like DDR is definitely here to stay

It must be remembered that if you want to upgrade the memory of a computer that uses DDR1, you cannot buy a DDR2 module and use it to supplement a DDR1 chipset. The slots for DDR1, 2 and 3 are different. Some motherboards, however, have slots for all these DDR formats. The booklet on the motherboard should tell you how to install additional RAM on your computer. Sixty-four bit processors often support more than 3.5 GB of DDR RAM. A 64-bit Windows Vista system, for example, will support memory of up to 128GB.

A DDR RAM operates at a lower voltage than an SDR RAM, resulting in lower power consumption. Though it has the same architecture as an SDR RAM, a DDR RAM has 184 pins, instead of 168. It also has a single notch at the connector, not two. The bus width of DDR memory is 64 bits per channel. Most DDR-based chipsets come with matched pairs of modules and are made for processors that are 1GHz or faster.
DDR memory is the latest in high-performance memory module technological advances. It offers twice the data bandwidth of conventional PC100 or PC133 SDRAM, and is particularly well suited for high-performance servers and workstations, which need optimal CPU-memory performance.

Memory Card Speed Explained

2008-11-14T12:07:00.001-08:00

Memory Card Speed:

Memory card speed is the card's performance with regard to how quickly data can be transferred to or from it. compare cards by the “X” speed, such as 80X, 150X,The card speed is often stated in -Times- ratings i.e. 12X, 40X etc (just as the speed of recordable CD's and DVD's is measured), and sometimes more specifically in megabytes per second (Mb/s).X is the baseline equal to a card accepting 150KB in one second. By today's measure, sub 20X represents a standard speed, 20X to 40X is mid-high speed and over 40X is high speed. The chart below shows the relationship between the two figures.

1X = 150KB per second
8X = 1.2 Mb/sec
10X = 1.5MB per second
12X = 1.8 Mb/sec
20X = 3.0 Mb/sec
25X = 3.8 Mb/sec
30X = 4.5 Mb/sec
40X = 6.0 Mb/sec
50X = 7.5MB per second
60X = 9.0 Mb/sec
66X = 10.0 Mb/sec
80X = 12.0 Mb/sec
90X = 15.0 Mb/sec
133X = 20.0 Mb/sec
150X = 22.5MB per second
300X = 45MB per second

Faster cards can accept more megabytes of information per second. But just how much of an advantage is a faster card? With some cameras, there isn’t much advantage to using a faster card, while others will benefit from the high speed.

The Secure Digital Association (SDA) defines three speed classes in order to let users identify speed and performance capabilities of SDHC cards and the host products. The speed class rating specifies a MINIMUM sustained write speed for SDHC cards.

Class 2 = 2MB per second
Class 4 = 4MB per second
Class 6 = 6MB per second

Notebook memory

Everything in life needs a little bit of upgrading from time to time. The computer industry sure does its own upgrading jig frequently and seems to make a fine scene out of it. The primary reason for upgrading your personal computers and notebooks is of course, the need for better performance to take care of applications that need enhanced calibration. When it comes to upgrading your computer, the most important segment that would go through the grind is the computer memory, because that is what will facilitate the running of bigger and more applications.

A system memory comes in two forms broadly – SD ram and DD ram, of which DDR memory offers faster and better performance in terms of data retrieval and dispersal, and is widely used today. Compared to the memory used in personal computers, the memory chip for notebooks come in smaller sizes to fit within the compact frame.
The denominations that usually come in the memory circuit are 512MB, 1GB, 2GB, 3GB and 4GB rams, although most notebook makers have started offering their products with higher configurations, so you need not upgrade much later. At least, that takes care of the obstacle of limited upgrading facility on notebooks.There are various types of memory in the market, but you would want to buy the one that suits your requirements ideally and is best for your notebook.

SLC vs. MLC Flash Memory

2008-10-30T08:33:00.000-07:00

SLC vs. MLC: An Analysis of Flash Memory

Single-level cell (SLC) and multi-level cell (MLC) Flash memory are similar in their design. MLC Flash devices cost less and allow for higher storage density. SLC Flash devices provide faster write performance and greater reliability, even at temperatures above the operating range of MLC Flash devices.

SLC Flash stores one bit value per cell, which basically is a voltage level. The bit value is interpreted as a “0” or a “1” and there are multiple values that an MLC cell can represent. The values can be interpreted as four distinct states: 00, 01, 10, or 11.

SLC and MLC Compared

Now that the differences between SLC and MLC have been explained, let’s compare their specifications to help further make a distinction between the two grades.

	SLC	MLC
Density	16Mbit	32Mbit	64Mbit

Express Card:

ExpressCard is a hardware standard replacing PC cards (also known as PCMCIA cards), both developed by the Personal Computer Memory Card International Association (PCMCIA). The host device supports both PCI Express and USB 2.0 connectivity through the ExpressCard slot, and each card uses whichever the designer feels most appropriate to the task. The cards are hot-pluggable. This is an open standard by ITU-T definition which can be obtained from the ExpressCard website. However, a US$2,500 fee[1] is required to access the documentation for non-PCMCIA members.

Uses
These slots can accept Firewire 800 (1394B), Serial ATA external disk drives, Solid-state drives, Wireless network interface cards, TV tuner cards, soundcards, additional memory and memory card readers, among other things.

Form factors:
ExpressCard supports two form factors, ExpressCard/34 (34 mm wide) and ExpressCard/54 (54 mm wide, in an L-shape) — the connector is the same on both (width 34 mm). Standard cards are 75 mm long (10.6 mm shorter than CardBus) and 5 mm thick, but may be thicker on sections that extend outside the standard form — for antennas, sockets, etc. The 34 mm form factor cards fit into both 34 mm and 54 mm card slots via a diagonal guide in the rear of the 54 mm slot that guides the card to the connector. The 54 mm card will fit in only a 54 mm slot.

SODIMM memory

2008-10-17T11:05:00.000-07:00

A SO-DIMM, or small outline dual in-line memory module, is a type of computer memory integrated circuit.SO-DIMMs are mainly used in notebooks, small footprint PCs (such as those with a Mini-ITX motherboard), high-end upgradable office printers, and networking hardware like routers.

SO-DIMMs have 72, 100, 144, or 200 pins. The 100 pin package supports 32-bit data transfer, while the 144 and 200 package supports 64-bit data transfer. This compares to regular DIMMs that have 168, 184, or 240 pins, all supporting 64-bit data transfer.

100-pin SO-DIMMs have two notches, 144-pin SO-DIMMs have a single notch near (but not at) the center, and 200-pin SO-DIMMs have a single notch nearer to one side.

SO-DIMMs are more or less equal in power and voltage rating to DIMMs, and as memory technology moves forward, both SO-DIMMs and DIMMs are available in equal speed (clock speeds such as 400Mhz PC3200, for example, and CAS latency such as 2.0, 2.5, and 3.0) and capacity (512MB, 1GB, etc.). More recent DDR2 SO-DIMM memory modules have clock speeds up to 800 MHz PC6400 and modules will soon be available with speeds of 1066 MHz PC8500.

SO-DIMMS are useful to design systems which have space restrictions and fit into small Form Factor systems/PCs.

O E M P C W O R L D- The world's memory value leader

SIMM (Single In-Line Memory Module)

A SIMM (single in-line memory module) is a module containing one or several random access memory (RAM) chips on a small circuit board with PINs that connect to the computer motherboard. This is an older type of computer memory.Since the more RAM your computer has, the less frequently it will need to access your secondary storage (for example, hard disk or CD-ROM), PC owners sometimes expand RAM by installing additional SIMMs. SIMMs typically come with a 32 data bit (36 bits counting parity bits) path to the computer that requires a 72-pin connector. SIMMs usually come in memory chip multiples of four megabytes.Sometimes you can get away with installing SIMMS, but they have to be installed in pairs.

The memory chips on a SIMM are typically dynamic RAM (DRAM) chips. An improved form of RAM called Synchronous DRAM (SDRAM) can also be used. Since SDRAM provides a 64 data bit path, it requires at least two SIMMs or a dual in-line memory module (DIMM).

What we do:

OEMPCWorld.com sells oem computer memory and Flash memory products at wholesale prices for PCs, Macs, Laptops, Music Samplers, printers, cameras and more. We offer a wide variety of popular and hard to find older 72p pin SIMMs, 168 pin DIMMs and 184 pin Rambus modules at unbelievably low prices as well as the latest DDR, DDR2 and DDR3 modules. From 16Mb to over 4.0GB, we have it in stock and ready to ship. Wide selection, great prices, unmatched service.

Why OEMPCWorld
Founded in 1998 OEMPCWorld.com can make claim to offering the best value on the market for configurator guaranteed memory. Its founders have been in the computer memory business since the very first IBM PC had 64K of ram back in 1984.

Some companies offer lower priced items but when you use their configurator they point you to a much more expensive option. This is called bait and switch. Offer low priced items on the shopping comparison sites but when you use the configurator it does not list these low priced items as compatible and they tell you to buy the higher priced item for guaranteed compatibility. We don't do that (assuming of course you are using our configurator). All our items are offered at one low price and the product we carry is guaranteed compatible or your money back. We do not offer multiple tiers or varying grades of products, that concept is absurd. Our products are guaranteed compatible and have a lifetime warranty; all products offer high value and the highest grade possible.

We also offer some of the highest levels of customer service and customer satisfaction numbers in the industry - customers rate our overall service at better than 9.3 out of 10 (see Bizrate)and 99.6% of our customer are either completely satisfied or very satisfied (based on 35 000 customer ratings since 1999). Our returns processing averages 4.5 days from receipt to ship, the industry average is 12 days.
Many competitors charge 15% restocking fees if the configurator is not used and if you do use the configurator then you pay for the higher priced item. They also charge a higher fee if you order over the phone or limit your free shipping options.

In addition, we offer excellent value across all our product lines, not just the new products, we still sell 32MB EDO SIMMs for the same price we sold them for 5 years ago, everyone sells new items like DDR and DDR2 for low prices and then if you need PC100 you pay twice what we charge.

High value across the entire product line.

We offer Lifetime Warranty on all memory products and ALWAYS offer an unconditional 30 day money back guarantee with no restocking fees.

168-pin DIMM Memory

2008-10-06T11:24:00.000-07:00

168-pin DIMM Memory

They contain 168 pins on the bottom of the circuit board. There are two notches on the bottom of the board and they must be aligned properly in order for them to be inserted. These memory modules are primarily used in newer computers and can be inserted one at a time unlike the SIMMs, which have to be inserted in pairs.

168-pin DIMMs are found in Pentium and Athlon systems. Each 168-pin DIMM provides a 64-bit data path, so they are installed alone in 64-bit systems. 168-pin DIMMs are available in FPM, EDO, PC66, PC100 and PC133.

The number of chips on a 168-pin DIMM may vary, but they have 84 pins on the front and 84 pins on the back for a total of 168. 168-pin DIMMs are 5.375" long and 1.375" high, and the heights may vary. They have two small notches within the row of pins along the bottom of the module.

USB flash memory pen drive

2008-10-03T10:41:00.000-07:00

USB flash memory pen drive

USB flash memory pen drive is a data storage device integrated with a USB (universal serial bus) interface. USB flash drives are typically removable and rewritable, much shorter than a floppy disk (1 to 4 inches or 2.5 to 10 cm), and weigh less than 2 ounces (60 g). Storage capacities typically range from 64 MB to 64 GB[1] with steady improvements in size and price per gigabyte. Some allow 1 million write or erase cycles[2][3] and have 10-year data retention,[4] connected by USB 1.1 or USB 2.0. USB Memory card readers are also available, whereby rather than being built-in, the memory is a removable flash memory card housed in what is otherwise a regular USB flash drive, as described below.

USB flash drives offer potential advantages over other portable storage devices, particularly the floppy disk. They are more compact, faster, hold much more data, have a more durable design, and are more reliable for lack of moving parts. Additionally, it has become increasingly common for computers to ship without floppy disk drives. USB ports, on the other hand, appear on almost every current mainstream PC and laptop. These types of drives use the USB mass storage standard, supported natively by modern operating systems such as Windows, Mac OS X, Linux, and other Unix-like systems. USB drives with USB 2.0 support can also be faster than an optical disc drive, while storing a larger amount of data in a much smaller space.

Rambus RDRAM memory

2008-10-02T12:02:00.000-07:00

Rambus RDRAM memory

Direct Rambus DRAM or DRDRAM (sometimes just called Rambus DRAM or RDRAM) is a type of synchronous dynamic RAM, designed by the Rambus Corporation.

Rambus Dynamic RAM memory technology, was intended to replace SDRAM and challenge DDR SDRAM as the standard memory used in computers. The first PC motherboards with support for RDRAM debuted in 1999. They supported PC800 RDRAM, which operated at 400 MHz but presented data on both rise and fall of clock cycle resulting in effectively 800 MHz, and delivered 1600 MB/s of bandwidth over a 16-bit bus using a 184-pin RIMM form factor. This was significantly faster than the previous standard, PC133 SDRAM, which operated at 133 MHz and delivered 1066 MB/s of bandwidth over a 64-bit bus using a 168-pin DIMM form factor.

Some downsides of RDRAM technology, however, included significantly increased latency, heat output, manufacturing complexity, and cost. PC800 RDRAM operated with a latency of 45 ns, compared to only 7.5 ns for PC133 SDRAM. RDRAM memory chips also put out significantly more heat than SDRAM chips, necessitating heatsinks on all RIMM devices. RDRAM also includes a memory controller on each memory chip, significantly increasing manufacturing complexity compared to SDRAM, which used a single memory controller located on the northbridge chipset. RDRAM was also two to three times the price of PC133 SDRAM due to manufacturing costs, license fees and other market factors. DDR SDRAM, introduced in 2000, operated at an effective clockspeed of 266 MHz and delivered 2100 MB/s over a 64-bit bus using a 184-pin DIMM form factor.

With the introduction of the i840 chipset, Intel added support for dual-channel PC800 RDRAM, doubling bandwidth to 3200 MB/s by increasing the bus width to 32-bit. This was followed in 2002 by the i850E chipset, which introduced PC1066 RDRAM, increasing total dual-channel bandwidth to 4200 MB/s. Also in 2002, Intel released the E7205 Granite Bay chipset, which introduced dual-channel DDR support for a total bandwidth of 4200 MB/s, but at a much lower latency than competing RDRAM. In 2003, Intel released the i875P chipset, and along with it dual-channel DDR400. With a total bandwidth of 6400 MB/s, it marked the end of RDRAM as a technology with competitive performance.

Rambus survived the obsolescence of RDRAM and moved to support DDR and DDR2 in the area of video card technology and in particular, PCI-E. Rambus also developed and licensed its XDR RAM technology.

SD Memory Cards :

2008-09-18T16:10:00.000-07:00

SD Memory Cards For Every Need:

SD memory cards are extremely versatile in where they can be used. Depending on the format, SD cards are usable in cell phones and PDAs, in cameras and computers. It's even possible to plug them into game consoles such as the Playstation 3 and the Nintendo Wii. Because of all the places in which they are used, they are great for transferring data around.

For example, you can take a set of pictures with your camera, take the SD memory card out and put it into your game console to look at the pictures on TV. Or you can take it to your computer and, with a card reader, plug it in and save the pictures to your computer's hard drive. You can also use your computer to download a java game for your cell phone and place it on your cell phone without being charged service fees for downloading data to your cell phone.

You can also use the same cards in multiple places. The smaller microSD and miniSD cards come with adapters that allow them to be used in regular Secure Digital devices. This would allow you to use the same SD memory card in your camera, and then take it out and put it in your PDA to save some documents before putting it in your computer's card reader to save your documents and pictures before clearing the card for other uses.

SD memory cards are convenient and portable - the largest SD card is 24mm by 32mm by 2.1mm thick - or roughly an inch square. This allows you to worry less about the space your data storage is taking up, and you can easily take more then one card with you in case your first becomes filled up.

Flash media is also durable - unlike camera film or notebook hard drives, SD memory cards can survive being shaken around, exposed to sun and heat, and can even survive getting wet, as long as it's entirely dry before being put inside a device again!

So if you've been looking for SD cards, whether for your cell phone, PDA or camera, take a look at what we have to offer. In addition to the various types of SD memory cards mentioned here, we also offer HDSD cards if your device is one of the newer ones that takes advantage of this new standard. You should be warned that your HDSD cards will not work with non-HDSD devices, however.

Cheap RAM MEMORY

2008-09-17T13:46:00.000-07:00

When looking for memory for your computer, there are several factors to deciding the right RAM, but two things tend to stand out - price and quality. While it might seem that to get great quality you also have to pay a great deal of money, but it is possible to find cheap RAM without compromising on quality.

Quality doesn't mean that the RAM itself is brand name, from Crucial or Kingston or OCZ or Corsair, but that the memory chips used in the RAM comes from a high-quality manufacturer, such as Infineon, Micron, Elpida, and Samsung among others. By finding cheap RAM that has been made by high quality manufacturers such as these, you can avoid paying a price premium for retail packaging and brand names.

These manufacturers are the same ones used by OEMs- Original Equipment Manufacturers, such as Dell, HP, Compaq, and more for their memory needs. By buying RAM in large quantities and not having to pay for retail packaging or branding, this memory is available at a cheaper price than ram you’ll find at your local computer shop or box store. OEMPCWorld.com offers high quality OEM ram at discount prices.

Our RAM covers all types of memory, from DDR and DDR2 memory for desktops to laptop RAM for new and older laptops alike. We also carry the specific models of RAM needed for Apple computers, including the G3 series that Apple itself no longer sells memory upgrades for on their website. This RAM is checked to make sure it will work correctly with your Apple computer's model. We offer a lifetime warranty on our RAM, as well as a 30-day money back guarantee if you are not satisfied.

If you're curious or don't know what sort of RAM your computer uses, take a look at the memory selection utility below. Click 'Check Your System' if you're browsing our site from the computer you plan to upgrade, and our tool will check your system and report back what RAM you currently have installed, the maximum amount of RAM your system can take, and possible upgrades for your system.

If you know the model of your computer, enter it in the model field and you can find the same information about your system, including exact information about what amount of RAM you currently have installed. Otherwise, if you built your computer yourself or are just curious, take a look at the RAM listings on the left. We have plenty of different types of RAM to choose from, as well as flash memory for PDAs, cellphones, cameras and other devices.

It links various kinds of digital equipment through its easy connectivity that supports a host of application formats and does not require the use of a PC. Further, the SD Memory card has the broad interoperability and compatibility needed to ensure that its applications will continue to expand far into the future. SD Memory Card is well on its way to becoming the de facto standard memory card for digital connectivity. Soon, the SD Memory Card will provide universal access to an even wider array of multi-media data. The ubiquitous network era is coming, and its key is the SD Memory Card.

Five Main Features:

Compact and Slim:

The SD Memory Card measures a mere 24mm by 32mm by 2.1mm. Its slim, compact design promotes easy handling, an important factor for a "bridge media" which you can move between different appliances.

The miniSD^TM Card (measuring 20 x 21.5 x 1.4mm (W x L x T)) and the microSD^TM Card (measuring 11 x 15 x 1 mm (W x L x T)), are also available as smaller factors of the SD Memory Card.

The miniSD^TM card was developed to meet industry demands for downsizing mobile phones. It is only 37% the volume of an SD Memory Card. Despite its tiny size, the miniSD^TM card offers all the benefits of the original SD Memory Card. By inserting the miniSD^TM card into the miniSD^TM adapter, you can share a variety of digital data among standard SD-enabled products.

The microSD^TM memory card is a functionally compatible with the SD memory card but is smaller in dimensions. The microSD memory card communication is based on an advance 8-pin interface and microSD memory card host interface supports regular SD or miniSD memory card adapter and operate as SD memory card.

2. Large Capacity
Small size is not enough. Capacity is equally important. SD Memory Cards are currently available in several capacities, and new 2, 4 and 8GB cards are on the way.

3. High-Speed Data Transfer
Increasing data volumes and the increasing range of digital content has created demand for memory cards with higher data transfer rates.

4. Copyright Protection

Flash Memory Options

2008-09-05T02:20:00.000-07:00

Flash Memory comes in a lot of different formats for a lot of different purposes. It can be used for everything from PDAs to cell phones, from holding pictures on cameras to pen drives that let you carry your documents more easily. The reason for the popularity of flash memory is its great storage in a small size, as well as the durability of the media. Flash media is more capable of surviving falling, being stepped on, or even having liquids splashed on it then film rolls and hard disks.

What types of flash memory are available? The most popular types include Compact Flash, Secure Digital, and Sony’s Memory Stick Pro. Compact Flash is most often used in personal cameras, and comes in sizes ranging from 32MB up to 8GB. Having a 1GB Compact Flash cards in your camera has become very common, enabling you to take photos all day without worrying about filling your card.

Secure Digital, or SD memory, is a much smaller format then Compact Flash, which makes it perfect for cell phones and PDAs where space is at a premium. At the same time, the tiny cards can carry nearly as much data as the larger Compact Flash cards. A 2GB Secure Digital flash memory can cost less than $20, allowing plenty of storage for your PDA or cell phone.

Memory Stick Pro is used in both cameras and the PSP portable gaming system. This Sony Brand memory tends to cost a bit more then Compact Flash and Secure Digital per megabyte, but is proprietary in a number of Sony produced devices.

Finally, there are also USB flash memory drives available, ranging from 64MB all the way up to 16GB drives. A 1GB drive can carry around more data then a CD can, and can be written and re-written to over and over again.

So if you're looking for flash memory for your camera, cell phone, PDA or PSP, take a look at what we have to offer. We also have Smart Media, MultiMedia and XD Picture Cards available for you to browse through.

What is DDR3 Memory?

2008-09-04T03:25:00.000-07:00

Several major DRAM manufacturer have made announcement, they are supplying the industry's first DDR3 devices and modules to leading PC industry developers for

evaluation by early 2007. Intel’s Bearlake chipset will be the first to support DDR3 and it is expected to arrive in the third quarter of 2007

Key Features

The DDR3 components are twice as fast as today's highest speed DDR2 memory products.
The first computer systems equipped with the advanced DDR3 memory technology are expected to arrive in 2007.
The main advantages of DDR3 are the higher bandwidth and the increase in performance at low power.
The DDR3 SDRAM devices will offer data transfer rates up to 1600 Mbps (megabits per second).
The supply voltage for the memory technology is being reduced from 1.8 volts for DDR2 to just 1.5 volts for DDR3 targeting a work day equivalent of battery time. The

voltage reduction limits the amount of power that is consumed and heat that is generated in connection with the increase in bandwidths.

Component densities: standardized from 512Mbit thru 8Gbit.
The most important densities will be 512Mbit and 1Gbit at the beginning, later on a 2Gbit and eventually 4Gbit component to follow.

Module densities: from 256MByte up to 8GByte for standard JEDEC modules.
Higher module densities beyond 8Gbyte for special applications like servers may be introduced later on.

Features:

DDR3 SDRAM Components:

Introduction of asynchronous RESET pin
Support of system level flight time compensation
On-DIMM Mirror friendly DRAM ballout
Introduction of CWL (CAS Write Latency) per speed bin
On-die IO calibration engine

What Types of PC Memory are There to Choose From?

What Types of PC Memory are There to Choose From?

So you're looking for PC memory to upgrade your system with, but aren't quite sure what you're looking for. Hopefully we can help you with some information about the various types of memory that are available to choose from.

The first type of memory to see widespread use is the 72-pin SIMM(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=72pin). Unlike the 30-pin SIMM that preceded it, the 72-pin version had a 32-bit data bus, requiring only one or two memory modules to fill the system's data bus, as opposed to the four or eight 30-pin SIMMs that had been required before that. The 72-pin SIMM these days will need to be installed in pairs, as almost all systems have a 64-bit data bus, and come in sizes ranging from 8MB to 128MB of memory. So if you want to add only 128MB of PC memory to your system, remember to get two 64MB memory modules(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=64M-EDO). Otherwise, make sure what type of 72-pin SIMM you need, as there are two formats - FPM (Fast Page Mode) and EDO (Extended Data Out), and not all motherboards will work with both types, not to mention that you will need to make sure that if you are adding RAM to your system, you install the same type as is already being used.

The replacement for the 72-pin SIMM PC memory is the 168-pin SDRAM(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=168pin). The 168-pin SDRAM has a few advantages over the 72-pin SIMM, but the greatest advantage is the 64-bit data bus used by the memory. This means that each module communicates with the system's data bus without needing to pair memory together, and allows for upgrading the memory one piece at a time. In addition, SDRAM operates at a higher speed then 72-pin SIMMs, operating at 66MHz(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=PC66), 100MHz(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=PC100) or 133MHz(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=PC133). The size of memory available in 168-pin SDRAM varies widely, from 32MB(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=32M-PC100) up to 1GB(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=1.0G-PC133) modules. The most common sizes in use these days are 256MB(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=256M-AP133) and 512MB(http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=512M-PC133).

PC100 vs PC66

2008-09-02T05:46:00.000-07:00

PC100 vs PC66

Use only PC66 Memory in TX and LX systems requiring 4 clock RAM Intel
Ver 1.0 Compliant. Do not use for VX systems. Specially made SDRAM
modules are required for VX systems.
Using the wrong memory speed in a system has a number of problems
associated with it, the first being it may not work. If the slower
memory does work in your faster machine then you have slowed down the
entire system and defeated the purpose of the new machine. For maximum
performance and cost effectiveness only use the correct memory per the
system specifications.

In an effort to answer some of the many questions regarding the "New"
PC100 bus memory I have assembled this white paper. I will focus only on
the differences and try to avoid a technical paper on how it works. The
paper is broken down into two parts with the first being the physical
differences between the two types of memory modules. The second part
deals with the systems issues with PC100 and PC66.

Physical Similarities and Differences
Intel created both the specifications for the PC66 and the PC100 SDRAM
DIMMs which tightly define their electrical characteristics. Both the
PC100 and PC66 SDRAM modules are 168 pin, 3.3 volt DIMM with SPD "Serial
Presence Detect". The signal pinouts or where the signal pins on the
connectors' locations is the same for both types of modules.

Both start out with the same basic concepts and similar physical
appearances but both are really quite different from performance
aspects. On the module itself, the PC100 specification requires that the
length of the traces be kept shorter than the PC66 modules. The shorter
the traces the faster the electrical signals can travel on and off the
module. The routing of the traces on the PC100, because they need to be
kept shorter, have to use a 6 layer PCB as
compared to a 4 layer PCB used on the PC66.

What is EDO Memory?

2008-09-01T05:51:00.000-07:00

Extended Data-Out (EDO) is a DRAM chip technology which improves memory performance 10 to 15% over equivalent Fast Page Mode devices.

Computer systems must be designed to take advantage of this performance increase EDO offers.

Intel's Triton Chip set, used in Pentium-class computers, are designed to do just that. EDO memory may be installed into most other computer systems but they will function and perform
as a Fast Page Mode memory module.

How does EDO Work?
DRAM's are designed as a matrix of bits. Each bit is accessed by a row and column address. A memory controller inside a computer system provides those addresses to access the data that each bit contains.

A 60ns DRAM will provide that data to the memory controller within 60ns. But there are certain time constraints for the memory controller to set-up the addresses, receive the data, and prepare for the next cycle. An entire memory cycle can range from 85 to 120ns.

Fast Page Mode can decrease cycle times by allowing the memory controller to access other data bits which are in the same row address. This saves time by not having to set up the next row address instruction. Data accessed in the same row is referred to as a "page".

Extended Data-Out (EDO) can improve cycle times even further by allowing the memory controller to begin a new column address instruction while it is reading data at the current address. Unlike FPM, the data output drivers are not turned off when the memory controller removes the column address to begin the next cycle. This saves approximately 10ns per cycle.

Memory Stick Pro and Pro Duo: More Storage for your PSP

2008-08-25T10:20:00.000-07:00

In addition to being useful in cameras and cellphones, Sony's Memory Stick Pro and Pro Duo are also used in Sony's PlayStation Portable console. Because they are the primary means of storage for the console, you can never have too much space. If it isn't game saves taking up the space, it might be music and videos, or movies. With all the media available for the PSP, it's no wonder that space might be a little hard to come by.

That's where we come in. Our Memory Stick Pro and Pro Duo cards are an inexpensive way to carry more game saves, more music, and more movies with you wherever you go. Even using a great deal of compression, a movie might take up nearly 256MB - leaving you almost no space for anything else. But for less then $45, you can pick up a 1GB stick and carry two or three movies with you, and still have room for music, game saves and more.

Interested in playing music on your PSP? Even a simple 256MB Memory Stick Pro Duo card will allow you to carry four hours of music with you, even more with a larger memory unit. The same size storage device lets you carry whole albums of photos with you to share with friends or enjoy looking at yourself.

2008-08-21T04:53:00.000-07:00

The cards come in storage sizes that make all of this possible. MiniSD and microSD come in 1GB or 2GB sizes for less then $40, and if you just need a regular-sized SD card for cameras or PDAs, there are even 4GB cards for less then $60.

SD memory cards are convenient and portable - the largest SD card is 24mm by 32mm by 2.1mm thick - or roughly an inch square. This allows you to worry less about the space your data storage is taking up, and you can easily take more then one card with you in case your first becomes filled up.

Flash media is also durable - unlike camera film or notebook hard drives, SD memory cards can survive being shaken around, exposed to sun and heat, and can even survive getting wet, as long as it's entirely dry before being put inside a device again!

So if you've been looking for SD cards, whether for your cell phone, PDA or camera, take a look at what we have to offer. In addition to the various types of SD memory cards mentioned here, we also offer HDSD cards if your device is one of the newer ones that takes advantage of this new standard. You should be warned that your HDSD cards will not work with non-HDSD devices, however.

SD Memory Cards For Every Need

2008-08-20T07:15:00.000-07:00

SD memory cards are extremely versatile in where they can be used. Depending on the format, SD cards are usable in cell phones and PDAs, in cameras and computers. It's even possible to plug them into game consoles such as the Playstation 3 and the Nintendo Wii. Because of all the places in which they are used, they are great for transferring data around.

For example, you can take a set of pictures with your camera, take the SD memory card out and put it into your game console to look at the pictures on TV. Or you can take it to your computer and, with a card reader, plug it in and save the pictures to your computer's hard drive. You can also use your computer to download a java game for your cell phone and place it on your cell phone without being charged service fees for downloading data to your cell phone.

You can also use the same cards in multiple places. The smaller microSD and miniSD cards come with adapters that allow them to be used in regular Secure Digital devices. This would allow you to use the same SD memory card in your camera, and then take it out and put it in your PDA to save some documents before putting it in your computer's card reader to save your documents and pictures before clearing the card for other uses.

Deciding the Best Time to Buy RAM

2008-08-18T08:50:00.000-07:00

When deciding to buy ram, how much is enough? That depends on what you want to do with your computer, and what your budget is. On average 1GB of RAM total is a good amount if you’re running windows, use your computer for surfing the web, but don’t use highly intensive software or play modern games. If you are a gamer, you'll need at least 1.5GB to 2GB of RAM or more to avoid slowdowns. Many people are taking advantage of the current low prices in the ram market to upgrade to two gigabytes of RAM, as the price is similar to what it cost for 1 gigabyte of ram just a year ago.

If you're worried that your system won't be able to accept more RAM, please take advantage of our online system checker. If you're surfing our website from the computer you want to upgrade, click the 'Check My Computer' button and it will return the best memory upgrades for your computer, including letting you know how many memory sockets your computer has and what speeds of memory it will take.

Deciding the Best Time to Buy RAM

2008-08-15T11:33:00.000-07:00

Is now a good time to buy RAM? Whether for your laptop or your desktop computer, RAM prices are low right now – and many people who are upgrading to the latest version of Windows Vista find the need to investigate a memory upgrade at the same time. RAM for your computer is both affordable and comes in larger amounts then it ever has been before. At current you can find 512MB for less than $40, and a gigabyte of memory for less than $70. At the same time that RAM prices have fallen and quantities have grown, so have the needs of the applications we use. Even the most critical programs, like Windows Vista, need more and more RAM these days to use without slowdowns or lockups.

Windows Vista recommends a gigabyte of memory to use the higher-end features such as the Aero desktop, and games are beginning to recommend having a gigabyte of memory or more for best performance. These memory needs are only going to grow, and it makes it critical now that if you don't have this amount of RAM that you pick it up, especially if you are looking towards upgrading your computer to use Windows Vista.

When deciding whether to buy or not to buy RAM it’s best to look at the current performance of the software that you spend the most time using - while programs are on the horizon that require a great deal more RAM, they have just been released and are not the standard, yet. You may have no particular need to upgrade your software right now.

Laptop Memory Upgrades (cont 3.....)

2008-08-06T07:22:00.000-07:00

Other then the physical differences, DDR2 memory runs at a higher clock rate then DDR, and thus can send more information per clock cycle. The clock cycle is a synchronizing cycle used by computers to keep data being sent and received at the same time, so that the data flows smoothly rather then bottlenecking at odd points. This prevents data being sent in bursts and then having to wait for the processor or RAM to process it. It also means request that data be resent that might have been lost while other data was being processed do not occur.

Despite running at a higher clock rate then DDR memory, DDR2 memory is slower internally as it requires more organization to match the higher external clock-rate. This means that while DDR2-533 might seem like it's much faster then DDR400, the difference isn't so great that you should throw out your old laptop and rush out to buy a brand new one. With more memory, your laptop with DDR400 can outperform a laptop that has DDR2 memory.

2008-08-05T07:49:00.000-07:00

Fortunately, as RAM prices have dropped for traditional desktop machines over the past couple of years, so too have prices fallen for laptop memory. OEMPCWorld.com offers 512MB of DDR400 laptop memory for a cost of only approx $50, and one gigabyte of DDR400 laptop memory for a cost of only approx $105. For newer laptops, memory is even less expensive - often less then $40 for 512MB of DDR2-533 memory, and less then $80 for a gigabyte of DDR2-533 memory.

Finally, it isn't hard to upgrade your laptop with more RAM. While you will want to consult your manual to determine the exact process for your laptop, most machines provide access to at least one if not both of the memory sockets under a panel in the back. By simply unscrewing this panel, users can add more laptop memory to their notebook computer quickly and simply. Be sure to check your warranty information card to see if this action may impact your service agreement.

What types of laptop memory are available? We carry almost every type of memory for portable computers in existence, from 100-pin and 144-pin SDRAM for older laptops, ranging in size from 32MB to 512MB, to newer 200-pin DDR and DDR2 memory, from 256MB to 2GB per module.

What's the difference between DDR and DDR2 laptop RAM? Despite both being 200-pin memory, they are physically incompatible, and won't work in each other's sockets. DDR memory has a notch near one side of the RAM at the base, where the pins are. This 'keys' the RAM and makes sure that it can only be installed the correct way, preventing the RAM from being accidentally installed backwards. DDR2 also has a notch, but its is located nearer to the center of the RAM. These two different keys prevent DDR2 memory from being used with a DDR controller, where they would not communicate correctly, and vice versa.

While your laptop is asked to perform the same tasks as your desktop computer, it isn’t always as powerful, nor as quick, simple, or inexpensive to upgrade. If your portable computer isn’t running as fast as it could, one of the simplest and cheapest ways to boost performance is to upgrade to more laptop memory.

To determine the correct type of RAM for your laptop, use our system checker located at our website here http://www.oempcworld.com/.

Most desktop computers offer four sockets for memory, and allow you to easily upgrade to as much as 4GB. However, laptop computers only usually have two memory sockets, and sometimes only one of those is available to the customer to add memory to without taking apart the entire laptop.

How much RAM does your laptop need? Much like desktop computers, the answer to this question depends more on the way you use your laptop. A laptop that is only used for business or schoolwork applications can see a noticeable benefit from upgrading to 1 gigabyte of laptop memory, from just 512k. If you plan to game on your laptop, or run graphically intensive applications like Photoshop, more memory will almost certainly help you run your programs more efficiently, and experience less slowdown.

What Types of Memory Stick Media are Available?cont....

2008-08-01T04:48:00.000-07:00

The Memory Stick Micro was created to compete against the microSD standard. The two devices are almost exactly the same size, with the Micro being only a millimeter larger in total. While it is more expensive, it is also twice as fast as microSD memory, transferring data at 20MB/second as opposed to 10MB/sec.

So if you have a camera or other device that uses Memory Stick media, take a look at the memory selection utility below. Just enter the model of your product, and our system can tell you what type of memory you need for that device. Or if you already know, take a look at the Flash Memory section, where you'll be able to find what you are looking for.

What Types of Memory Stick Media are Available?

2008-07-31T07:55:00.000-07:00

Memory Stick media was first launched by Sony in 1998, and has received several revisions since then. The original format is no longer in use, but its name is still used in general to describe similar types of products. They are used in Sony and Sony Ericsson products for the most part.

The original Memory Stick media ranged in size from 4MB to 128MB in size, however could not expand to include more then 128MB of storage due to architectural limitations. In response to this, Sony developed the Memory Stick Select (http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=MSG ) first, which is similar to having two sticks sharing the same case. To switch from one to the other, a physical switch is flipped, and it switches from one partition to the other. While potentially offering more space, the Memory Stick Select was unpopular due to the inconvenience of having separate pieces of memory that could not work together in the same device.

Sony's next offering is the Memory Stick Pro (http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=MSP), which solved the space limitation and allows for up to 4GB of data, a great increase over the original. Even better, it was backwards compatible with the majority of the older devices. While the 4GB modules (http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=MSP4096&Category_Code=MSP) are somewhat expensive at $90, 2GB (http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=MSP2048&Category_Code=MSP) and lower modules are easily affordable, all for under $60, and many for less then $30.

Currently Sony has three other versions of the Memory Stick on the market - the Memory Stick Duo and Pro Duo (http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=MSP), and the Memory Stick Micro (http://www.oempcworld.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=M2). The Duo is smaller then the original, about two thirds of the size. However, it comes with an adapter to let it plug into normal stick readers. The Duo comes in the same capacity as the original Memory Stick, while the Pro Duo has expanded storage capability, like the Pro. The two versions were created for use in smaller, pocket-sized cameras and cell phones.

SDRAM vs. RDRAM, Facts and Fantasy

2008-07-29T09:31:00.000-07:00

SDRAM vs. RDRAM, Facts and Fantasy:

Intel's decision to chain the Pentium processor to RDRAM system memory has raised quite a controversy. This article will get into greater detail about Rambus, SDRAM, RDRAM and the relationship between Intel and Rambus and why both these companies keep backing their technologies.

We'll address most of the issues that generally seem to be considered 'disadvantages' of Rambus technology and investigate whether these are based on fact or fantasy. At times we'll go deeper into technical detail than some of you might be willing to follow, in order to prove a point or accurately describe a specific function. But overall we’ve tried to keep the technical details and analysis to a minimum and as basic and straightforward as possible. However, we’ve made sure that our benchmarking setup, the suite of benchmarks used, and our technical analysis is reproducible by anyone wishing to do so. We at HardwareCentral always aim to keep our benchmarks and reviews as objective as possible, and this SDRAM vs. RDRAM article is no exception.

In the following pages you'll find an in-depth analysis of Rambus' RDRAM, what makes it tick, what the benefits are and above all we'll look into its technological advantages, as those will most likely determine whether RDRAM is worthwhile or not. The analysis will be followed by a discussion of benchmarks and why we’ve chosen to use this specific set, as well as an analysis on how each particular benchmark makes use of system resources.

We'll round off this article with a broad range of real world benchmarks, aimed at exploring the technological advantages and disadvantages as pointed out in the theoretical analysis of the previous pages, checking theory with practice. And, naturally, the conclusion will summarize the results as well as give our verdict on SDRAM vs. RDRAM.

Eee, Atom, Aspire, Wind: It's a Small (Notebook) World at Computex
What comes after Eee? Everybody from HP and Acer to Dell and MSI, not to mention class leader Asus, wants to star in the second generation of low-cost, low-weight, just-right-for-traveling-light laptops. This week's Computex show is packed with the ultraportable notebooks known as netbooks, with Intel's new Atom CPU in a prominent supporting role -- and Nvidia and VIA waiting in the wings.

Platform Trends: AMD/ATI: Slowdown? What Slowdown?

Both product lifespans and prices are falling for PC graphics cards, but that hasn't stopped AMD from pushing the envelope with a new ATI Radeon HD 4000 series marking the industry debut of GDDR5 memory technology -- and a new brand campaign telling retail shoppers not to settle for the usual integrated graphics.

Tinsel and GlamourFalling Off the Catwalk

The economy's in a slump and PCs are in danger of becoming interchangeable commodity products anyway. So how can hardware manufacturers perk up sales and prop up profit margins? Chrome trim and pretty colors, of course, as vendors ranging from Dell to Staples introduce limited-edition artistic cases and fashionable decorations. HardwareCentral editor Eric is bemused. Apple is unworried.

Platform Trends: DDR-3 Heads for the Mainstream

Long ago, Intel decided that desktop PCs should use RDRAM, and riots in the marketplace forced a reversal. Now the processor giant is spurring the move from today's DDR-2 to higher-bandwidth, more energy-efficient DDR-3 memory for desktops -- and, with the forthcoming Centrino 2 spec, notebooks as well. Vince Freeman looks at the pros, cons, price points, and performance issues surrounding the transition.

Platform Trends: AMD Hits a Triple with the Phenom X3

Market-wise, the gap between dual- and quad-core PC processors may not be big enough to drive a truck through. Or a subcompact. Or a shopping cart. But AMD is betting it's got room for a new family of triple-core CPUs. Will the Phenom X3's sales pitch of better multitasking for the price of a dual-core attract buyers? And what happens if tri-core demand exceeds AMD's supply of didn't-quite-pass-inspection quad-cores?

Platform Trends: The Wild World of Graphics Cards

At the rate they're releasing products, Nvidia and AMD/ATI may soon run out of model numbers. Desktop PC graphics cards have never had shorter life spans or quicker price cuts, as last year's performance champions are suddenly mid-market or even destined to be entry-level cards. Will GDDR-5 keep the mad momentum going? Is Asus serious about showing off not a dual- but a triple-GPU one-card solution?

Platform Trends: X4 Marks the Spot

Okay, AMD Phenom, take two, quiet on the set! (Really quiet, in the case of the 65-watt quad-core for home-theater PCs.) Yes, four months after its bumpy introduction, AMD's top processor is getting a do-over -- raising clock speeds; squashing the TLB bug that cast a shadow over the first Phenoms; and adopting easy-to-understand X4 labels for quad- and X3 for tri-core CPUs. Radically undercutting Intel's Core 2 prices shouldn't hurt, either.

Platform Trends: Intel Deploys Its Troops

What's the only thing that can hurt sales of Intel's dominant Core 2 Duo and Quad processors? It's not AMD's Phenom -- it's buyers deciding to wait for the products the chipmaker has in the pipeline. CPU guru Vince Freeman explains why the release of Intel's 45-nanometer-process quad-core "Yorkfield," higher availability of the dual-core "Wolfdale," and a new desktop chipset and quad-core laptop processor should give Intel a Q2 for the record books.

Platform Trends: Shifts in the Multicore Landscape

The state of the art's not just top of the line: After unveiling its 45-nanometer-process engineering with quad-core Xeon and Core 2 Extreme CPUs, Intel has finally added affordable dual-core versions to its Core 2 Duo line. But while these "Wolfdale" processors win raves, AMD is making moves elsewhere -- giving China first dibs on a dual-core Sempron and preparing to add tri-core models to its flagship Phenom series.

PCs for Five C's

Grand Openings is back! Well, half back, anyway, as HardwareCentral's once-quarterly quest for the best notebook and desktop PCs priced under $1,000 returns -- with a rock-bottom new budget of $500. We're not talking about humble family PCs, either: Join our online hunt for dual-core CPUs, hefty hard disks, and a sufficient-for-Vista 2GB of RAM, hitting system vendors' own Web sites, retail chains, and discount warehouses.

SDRAM vs. RDRAM, Facts and Fantasy

Introduction

Intel's decision to chain the Pentium processor to RDRAM system memory has raised quite a controversy. This article will get into greater detail about Rambus, SDRAM, RDRAM and the relationship between Intel and Rambus and why both these companies keep backing their technologies.

We'll address most of the issues that generally seem to be considered 'disadvantages' of Rambus technology and investigate whether these are based on fact or fantasy. At times we'll go deeper into technical detail than some of you might be willing to follow, in order to prove a point or accurately describe a specific function. But overall we’ve tried to keep the technical details and analysis to a minimum and as basic and straightforward as possible. However, we’ve made sure that our benchmarking setup, the suite of benchmarks used, and our technical analysis is reproducible by anyone wishing to do so. We at HardwareCentral always aim to keep our benchmarks and reviews as objective as possible, and this SDRAM vs. RDRAM article is no exception.

In the following pages you'll find an in-depth analysis of Rambus' RDRAM, what makes it tick, what the benefits are and above all we'll look into its technological advantages, as those will most likely determine whether RDRAM is worthwhile or not. The analysis will be followed by a discussion of benchmarks and why we’ve chosen to use this specific set, as well as an analysis on how each particular benchmark makes use of system resources.

We'll round off this article with a broad range of real world benchmarks, aimed at exploring the technological advantages and disadvantages as pointed out in the theoretical analysis of the previous pages, checking theory with practice. And, naturally, the conclusion will summarize the results as well as give our verdict on SDRAM vs. RDRAM.

Reading your register settings under Linux:

Register values for the 440BX PCIset are listed in the 440BX Specification in section 3.3. 3.3.24 lists the values for tCL, tRCD and tRP. A 16 bit address under control register 0 (Device 0), at address offset 76h77h defines these values. The default value is 00h. The three least significant bits are defined such that:

Bit 0:
SDRAM RAS# Precharge (tRP). This bit controls the number of DCLKs for RAS# Precharge.
0 = 3 clocks of RAS# Precharge.
1 = 2 clocks of RAS# Precharge.

Bit 1:
SDRAM RAS# to CAS# Delay (tRCD). This bit controls the number of DCLKs from a Row Activate command to a read or write command.
0 = 3 clocks will be inserted between a row activate command and either a read or write command.
1 = 2 clocks will be inserted between a row activate and either a read or write command.

Bit 2:
CAS# Latency (CL). This bit controls the number of CLKs between when a read command is sampled by the SDRAMs and when the 82443BX samples read data from the SDRAMs. If a given row is populated with a registered SDRAM DIMM, an extra clock is inserted between the read command the when the 82443BX samples read data. For a registered DIMM with CL=2, this bit should be set to 1.
0 = 3 DCLK CAS# latency.
1 = 2 DCLK CAS# latency.

If you wish to read the values of these bits you can download and run 440bx.c. Compile 440bx.c with "gcc -O -c timing timing.c." The program will dump the bit values of address offset 76h of device 0. For example, a board set to 3-2-2 would read something like:

*** 440BX SDRAM Memory Timing ***

CAS# Latency: 3 DCLKs
RAS# to CAS# Delay: 2 DCLKs
RAS# Precharge: 2 DCLKs

CAS delay (tRCD).

2008-02-14T15:32:00.000-08:00

CAS delay (tRCD).

Data is read out sequentially, synchronized with the positive edge of CLK. Data is sequentially bursted according to the burst mode set in the Mode Registry. The burst mode may be set to 2, 4 or 8 words or even to a full page (the entire column). The initial data from the READ command is available (data out) after a period equal to the value of the the CAS Latency (CL) as set in the Mode Registry.

Therefore the total access time to the first data word is generally equal to tAS + tRCD + CL. This may be something like 1+2+3 = 6. Subsequent data is bursted out synchronous with the clock at one clock per word for the duration of the burst mode.

As noted above the PC100 specification requires a minimum standard of 3/3/3/8. The specification also requires a 6ns or less Access Time from Clock (tAC 6ns). tAC is basically the time in nanoseconds for data to be read.

Most PC100 modules have a CL of 3. The Samsung -GH and Micron -8D and -8E have a CL of 2. Modules with a CL of 2 are difficult to produce in ample yields and are therefore much more expensive than modules with a CL of 3. The lower CL only increases total SDRAM performance marginally (~5%) and therefore are considered to offer too little bang for the buck. However, CL 2 modules are of some interest to those who over clock their systems to bus speeds of 112MHz. We do not suggest over clocking the bus speed. However, we do carry the faster modules for those who are interested in them.

The values listed in specifications may be confusing because they are alternately listed in clocks tics or nanoseconds. For example, the RAS to CAS delay, tRCD, is the number of clock cycles allowed between the ACTIVATE (RAS) command and the READ (CAS) command. The value of tRCD is generally 20ns or 30ns (2 or 3 clocks). The value of the tRCD latency in nanoseconds may be divided by the bus speed in nanoseconds (100Mhz is 10ns) and then rounded up to the nearest whole clock value. For example a tRCD of 20ns would yield a latency of 2 clocks cycles (20ns / 10ns). The RAS Precharge (tRP) is typically 20ns of 30ns. (tRP is analogous to the CAS# before RAS# (tCBR) described above for EDO RAM).

We have found that the values set in the SPD are frequently incorrect. Indeed, it is not possible to set these values correctly for all bus speeds. These values should be overridden. Lets look at CAS latency (CL) as an example. Recall That CL is the time from the READ command to the first data out. If a module is rated as 3/2/2/8 (which most are) to what value should the SPD CL be set? Suppose the module is used on a 440BX board with a 333MHz CPU. The bus speed would be 66MHz which has 15ns tCK. A 3/2/2/8 modules has a CL of 30ns. Therefore on a 66MHz bus the CL should be set to 2 (30ns/15ns) in the SPD. Suppose the same module is used on the same 440BX board with a 400MHz CPU using a 100MHz bus. The bus speed would be 100MHz which has 10ns tCK. A 3/2/2/8 modules has a CL of 30ns. Therefore on a 100MHz bus the CL should be set to 3 (30ns/10ns). To which value should this module's SPD be programmed? 2 or 3? There is no correct answer. It doesn't appear that Intel took this into account when writing the specifications of the SPD. In actual practice you'll find SPD set to very odd values indeed. Therefore, override these values in your BIOS and set them up by hand the old fashioned way. Generally you'll set these values to 3/2/2/8.

What happens if you don't set the module parameters correctly? If you set the parameters to conservatively your system may perform about 20% too slow. But no other harm will be done. If you set your module parameters too fast, you will not damage the module nor the motherboard. However, you will end up with data corruption. This corruption may be insidious and difficult to detect at first. But eventually it will catch up to you. To test for data corruption try unpacking large software packages like the entire X Windows system and running check sums. This seems to be a fairly good test for this type of data corruption.
