Anyway, for the 24/7 work, I'd like to keep the power savings setting in BIOS (SpeedStep, C1) so that the CPU only kicks when needed (right now it's working at some 1.14V and 1.8GHz, with fans almost stopped; when I do some HDV rendering it goes up to 3.10 GHz and the temps never exceed 75C). FSB at 310 MHz is the max I can get without increasing the Vcore from Auto (which is the only setting possible when using C1/SpeedStep). I have overclocked the RAM to some 466 MHz (5:5:5:18) at 2.20V (Geil DDR2-800). What I'd like to do is increase the FSB a bit higher, so that the overall system performance is better - if the CPU temps will get too high, I can go down with the multiplier to 9 or 8 (currently 10).

My questions:

1) which voltage settings (apart from RAM already at 2.20, and Vcore that I need to leave at Auto for the above reasons) should I change in order to assure stability with FSB = 333 or higher?

2) is it normal that Ai Booster shows Vmem higher that that entered in BIOS? When I want to run my Geil sticks at 466MHz 4:4:4:12, I need to enter 2.25V and then AiBooster shows zero (is if it was outside the range allowed, which worries me). With 2.20 in BIOS, AiBooster shows 2.30V (the max allowed by Geil). So, is it safe at 2.25V in the BIOS?
1) vmch = 1.65, vfsb = 1.20, and of course, and most importantly, vcore. Unfortunately you're going to have to get off the Auto vcore and find a comfortable voltage that will get you a stable clock without getting your temperature too high.

2) Don't use AIBooster. It's buggy, crap software. I know speedfan shows some, but can't recall if it shows vfsb as well.. Another poster will have to verify, or recommend a better program.
