10*360 was already stable. There was never any problem with that. Even 10*370 was stable @ 1.3v. It was going HIGHER that started giving problems. 10*380 wasn't fully prime stable even at 1.3875v, and I didn't like the temps, and 10*400 didn't post. But at a 12 multiplier, I had the system actually post at 4.36 ghz (accident; didn't know the FSB was that high), didn't even bother to TRY going out of BIOS; no way I'm going to try to make that stable on a 975X...would be a big fight between trying to find out if the prime crashes were caused by the CPU or the FSB >.>
But it ran perfectly at 4 ghz and 1.3875v at a 12 multi. But the temps got too high so I'm lowering the voltage a tad. I reached my goal anyway--4 GHZ with a quad

I've settled on 12*333 (4 ghz) and 1.3625v for gaming and stock (9*333=3 ghz) for 24/7. When I upgrade the board to something that can clock quads on a HIGH FSB without puking, then I'll see how far the chip can truly go. I don't want to have to test a 15 or 16x multiplier to try go past 4 ghz, at a rediculously low FSB >.>

I don't expect I will be able to hit 4.5 ghz on air, even on a X48, without insane amounts of voltage (I'd have to toss the Tuniq and get an Ultra 120 Extreme or that other new HS people are using, for anything above 1.4v)
