DDR SDRAM MEMORY

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 is different from SDRAM memory and can only be used in systems designed specifically for DDR SDRAM memory

DDR SDRAM memory has 184 pins, where as SDRAM has 168 pins. DDR SDRAM Memory is a new type of SDRAM that is able to double the read / write speed of the previous generation of SDRAM memory. There are currently, PC2100 (DDR266), PC2700 (DDR333), PC3200 (DDR400), PC4200 (DDR533). These DIMMs are 184 Pin in size and are not interchangeable with older SDRAM modules.

DDR SDRAM Modules are available in PC3200, PC2700 and PC2100.
