DDR vs SDRAM

[Nicksixxfour]

What's the difference between DDR and SDRAM memory? Can I use DDR memory with pentium system? Thanks🙂

DDR means "double data rate" and basically runs "twice" as fast as SDRAM since it reads on both edges of the clock cycle.

SDRAM is slower than DDR, and DDR is slower than rambus (this is debatable though!)

Rambus is used in all the new pentium systems. All the older PIII, PII's etc, still use SDRAM

DDR is only currently used in AMD athlon systems.

There are a few P4 motherboards on the market that run on DDRAM now.

Actually there are P3 boards that use DDR aswell, using VIA/ALi chipsets

Asus TUA266 which is Tualtin compatible
Asus CUV266

I haven't read any performance reviews of either, so I don't know if they are worthwhile or not.

Can you tell me what they are? Thanks
