Just a quickie, if my E4300 is set to a 337.5 MHz bus, is the maximum speed of my RAM automatically restricted to 675MHz? If I try to set the FSB to unlinked and the RAM to 800, the computer refuses to boot. If I set the RAM to 675, it works perfectly. I have noticed this on another computer I built where despite having 2GB of DDR2-800 OCz RAM present only reports a 4.8 Vista score, the same as the stock clocked CPU.
