Hello. I have an Abit IP35 Pro board. And I just bought a Q9550. My overclocking has not been going as well as I had opened.

I get get up to 3.825GHz stably. But it takes some voltage I'm slightly uncomfortable with.

vcore: 1.39
vtt: 1.30
mch: 1.25
ich: 1.05
ichio 1.5: 1.5 (I assume this is the CPU PLL?)
gtlref: 67% for both cores

I've tweaked around with the mch, ich, ichio, and gtlref. None of these seem to make any difference for me in my current situation. The Vcore and VTT did definitely help though.

But it seems like so many people are doing so much better with less voltage. It could just be bad luck. But I'm wondering if a P45 board would do better.

I have about 0.04 volt drop between idle and Prime 95 load. I'm not really into doing vdroop mods because I can't solder for crap, I'd just ruin the motherboard.
