11mins ortho, still running, voltage just refers to some L724A, so may not be so exact.......

You should be running smal fft's instead of large for CPU stability. Also you should use prime95 instead of orthos. it stresses all 4 cores with the 1 program. I can pass orthos for hours yet fail prime95. I think orthos may be outdated.

WHERE ARE ALL THE DOUBTERS NOW HEY

4GHZ prime even if not for too long

I have 5 1/2 hours prime @ 4Ghz http://www.xtremesystems.org/forums/...&postcount=389. Basically shut it down because I was tired and didnt want to leave it unattended. I am sure this chip has allot more, but need another board.

I will wait for X38 tho. I am happy with 4Ghz

I set the affinity to the core so it is 100% full. ortho and prime95 should be the same.
Still doubt whether should use small fft or large, but I find large is more stressing... Anyway, I shall try small fft tonight

yup if small fft pass for few mins, we can go large fft.. large fft more stressing for me too on cpu

I agree regarding large ffts. Had overclocks pass small ffts without issues but would fail large ffts fairly quickly (and NO!, it wasn't any ram issue).

Large ffts - priority-9, if an overclock can pass that then it's pretty stable in my mind.

I've got my Q6600 G0 @ 3.8 GHz (1.5625v Bios, 1.5v Everest) benching Cinebench. It's hitting 62c, so I'm sure its not prime stable, but it's on air with my U-120-X. I'm not comfortable juicing it with 1.5v, so I'm leaving it there.

It's running 3.6 GHz (1.45V Bios, 1.39 Everest) Prime stable as my 24/7 clock.

I would like to know how you people think large fft stresses the cpu more than small fft's.

large fft's are for the ram and small fft's are for the cpu.

Phucked if I know, but if you take the ram out of the equation (meaning it's error free and stable - stock) and run your cpu overclock using small ffts - priority-9 it's more likely to pass this than it is when running large ffts priority-9. Why?, I have no idea, but quite a few people have confirmed these findings as well.

Nice one, how much vCore?
