I'm looking into building a new higher performance gaming machine, and I have most of my components more or less decided on... except my memory. As far as I can see, no motherboards support any higher than DDR400 (PC3200). Why then do some DIMMs come in PC3500 and higher? Wa da fa? If NO motherboards support it, why are there so many choices for the higher grade stuff?
Next question: what's DDR2? Does it have something to do with the higher grade memory? If so, why do some plain ol DDR still come in 3500+? I assume DDR2 is just a faster version of old DDR - if that's the case, do I need a motherboard to specifically support it, or will any DDR mobo work?
I'm planning on overclocking the RAM, so what type should I get? I'm probably gonna start with Corsair XMS dual channel stuff... but is there any reason I should shy away from this RAM? Does some high end RAM overclock better than others?
And what ever happened to Rambus RAM?
Thanks for your help!
