Silly RAM question

carderne said:
I currently have a 775 P4 in a socket775 mobo with DDR400 ram.

I assume it will be fine if I get a new mobo with DDR2 ram? What I mean is, my CPU doesn't affect what RAM I can use...

I'm not to sure either, I've been using amd for the past eternity, but I can say that there's a chance that the cpu won't support the new memory, but thats with the amd cpu's.
 
It will work perfectly.

AMD's have got the memory controller onboard the CPU (the reason why they perform so well compared to P4's), while Intel puts their memory controller on the motherboard chipset.

The next Gen AMD's will support both DDR2 and DDR3 on the CPU.

Intel is also moving the memory controller onto the CPU at end of year.

Yes, it should work seamlessly.

RAM speed and type is determined by the board's chipset

AFAIK, that affects the "FSB". More truthfully, AMDs processors don't have a Front Side Bus (it is an aging technology that Intel, as you correctly said, are also doing away with in their new Nehalem microarchitecture).

So while there is often a proportionality relationship between FSB frequency and RAM clock frequency, it isn't always 1:1.
