What DDR SDRAM memory to buy?

The the latest chipsets like the AMD Athlon XP at present the PC2700 DDR333 matches the bandwidth. Consider atlease 256MB DDR Memory as your bare minimum when you buy. It would be good if you can investing in 512MB PC2700 DDR333 as it will spare you the headache of doing a memory upgrade in future. The peformance of the DDR memory module you buy depends on the chips that make up the DDR module itself. Since the module is made up of different memory chips the ultimate speed of your module depends on all of them being able to reach the same speed.

For an example we can take the graphic cards of NVIDIA who on testing their graphics chips find the ones that can go to the highest speeds and sell them separately as their top chip, while the rest that do not quite reach the ultimate speed are sold as a slower speed processor. This way they get two products for the price of one. The same applies to memory chips. Some memory companies do the same for DDR PC2700 & DDR PC3200 (DDR333) & (DDR400) which can be slower memory chips that are able to reach the next speed level. So if you buy say DDR PC2700 you can at least be assured that it will work at 166MHz and a little more. This means that with the AMD Athlon XP FSB you can safely increase its speed and know that the DDR memory will work.

DDR SDRAM Memory | DDR2 SDRAM Memory | DDR3 SDRAM Memory

DDR3 is the next-generation, high-performance solution for CPU systems. DDR3 memory are twice as fast as today's highest speed DDR2 memory products. Select your DDR3 Memory from the following.

DDR2 introduces some new features which allow it to ramp up to much higher speeds (with correspondingly higher bandwidth) and higher memory densities, all the while using less power. DDR2 memory uses a new form factor, a 240 pin DIMM (Dual Inline Memory Module) which is *not* compatible with current DDR memory slots. Upcoming chipsets by Intel and other manufacturers will support DDR2 specifically, and are not backwards compatible.

DDR SDRAM for desktop computers DIMMs have 184 pins (as opposed to 168 pins on SDRAM, or 240 pins on DDR2 SDRAM), and can be differentiated from SDRAM DIMMs by the number of notches (DDR SDRAM has one, SDRAM has two). DDR for notebook computers SO-DIMMs have 200 pins which is the same number of pins as DDR2 SO-DIMMs. These two specifications are notched very similarly and care must be taken during insertion when you are unsure of a correct match
