Assuming you had to bump your CPU voltage to 1.45 to achieve stability, some other BIOS tweaks to achieve a higher overlock would be to tighten (or loosen) your RAM timings if possible if you haven't not already. You could also lock your PCI clock to 33 1/3 AND increase your PCI frequency to 110 or more if you hit a wall. Also trun off lame BIOS options like speed spectrum, turbo cache, etc. for example
I never changed the voltage. I would assume it changed automaticly since the default is 1.35. Should I mess with the multiplier instead of the FSB? When I set the FSB to auto and change the multiplier to 14 I can get the same speed of 3.5 Ghz but the FSB remains at 1066. The only thing I'm concerned about is if I overclock it by jsut the FSB which I did does it loss performace or would it be better to go at 3.5 Ghz /w 1066 FSB?
Maybe you can help on this one.... If you could up the Multiplier AND up the FSB which would you choose to UP? Or, would you up both to the desired speed? This one I just can't get an answer on. Also with FSB and Multiplier, what is the pros and cons of choosing one over the other?
