Okay I'm a noob, we all know this. When I buy ram and it says ddr 1000 or 1200 is this the native speed that it runs at from factory. Is the concept same a cpu's as you buy a cpu that runs at 800fsb or 533fsb or w/e. Then you change the fsb through bios etc? Same concept right? I was wondering if I bought pc 10000 ddr2 would I be able to run it in a mobo that stats 6400 is the highest I can run. So is it more so dependent on the ram or the mobo?
