Generally speaking DDR is for intel CPU's only. I posted something this morning in response to a question on another board this morning and am going to paste part of my response below. I'm a big-time AMD advocate and don't have a lot of first hand experience with DDR2 so can't give you any detailed information. As manufacturers tool up for DDR2, it is expected that the price differential will close rapidly and DDR2 pricing is expected to drop significantly. Now for the paste re: a few comments - Q&A's regarding DDR2Q: Which available chipsets support DDR2 memory?
As of July 1, 2004, Intel has released the 915 and 925 chipsets supporting dualchannel DDR2 (400 MHz and 533 MHz only) as well as the E7525 workstation chipset supporting dual-channel DDR2-400 memory.Q: What is the difference between the Intel 915 and 925 chipsets?
The 915 chipset, code-named Grantsdale, is the mainstream desktop chipset while the 925 chipset, code-named Alderwood, is for performance desktops. The 915/925 chipsets are positioned in a similar way to the older 865/875 DDR chipsets.Q: Does the Intel 915 chipset support DDR or DDR2?
It supports both.Q: What latencies will standard DDR2 DIMMs support?
JEDEC DDR2 specifications define standard DDR2 CAS Latencies of 3, 4, and 5:
– 400 MHz DDR2: CAS 3 (3-3-3)
– 533 MHz DDR2: CAS 4 (4-4-4)
– 667 MHz DDR2: CAS 5 (5-5-5)Q: Will there be platforms supporting DDR2 memory with AMD processors?
No. AMD has publicly said that it will not support DDR2 until possibly 2005. Because AMD’s processors incorporate DDR memory controllers (inside the processor), DDR2 memory support cannot be added by chipset manufacturers such as VIA or SiS. Only AMD can change the memory technology supported by its processors.
DDR or DDR2
DDR2: 400/533 MHz
DDR2 memory only
DDR2: 400/533 MHz
