I know i must be mis-understanding something here. The current processors, looking at the E6xxxs even when OC'd have FSBs of around 400-500mhz. Now most people seem to run this at 1:1 with thier RAM, usually pc6400 which is rated to 800mhz! Surely this is totally excessive and why would we then need RAM with timings all the way up to 1000mhz if we are only using 1:1? Is there some doubling thing with the FSB which i have forgotten about? Thanks for clearing this up for me!!
