Re: What's more important, CPU Multiplier or CPU FSB?
^ What Sy said.
Find your highest FSB with a low multiplier, lower it a bit, then start upping the multiplier until you find the sweet spot. Then it's just fine tuning.
Set your memory timings a bit loose while your messing. Voltages are just trial and error, but don't go too high.
EDIT: oh yeah. While you're upping the FSB make sure the RAM doesn't go over 800MHZ. You can set this after you've found the right FSB setting by altering the FSB-RAM ratio.
