I can run 4 passes stable with 1.20V under load but than it fails.

It's something that I expected that wouldn't be possible because of the high GFlops. LinX gives me GFlops around 56.700 and I find that very impressive for 4.05GHz.

An other interesting thing is that I don't need high Vtt. I was running with 1.14V real. I did try higher, up to 1.26V, but it fails with a system crash with higher Vtt. I guess I don't need it higher for 9 X 450MHz.

What they are saying about low VID and higher temps is really true. The CPU temperature reached 57° Celsius under LinX load. The room temperature was 27° Celsius and the coolant temperature was 29° Celsius.

It's nice to have a low VID Q9650 under water with these high temperatures. I don't think that it would be possible to run it at 4GHz+ with air cooling. The CPU temperature would reach to high and result in an unstable CPU.

So far my first experiences with this Q9650.

I'm going to try to get it LinX stable for 25 passes and post some screenshots with my results. I'll do this when I've got some time to play a little more with this nice chip.
What's the highest stable frequency you could get with 1.2v vcore under load?
