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 I think orthos may be outdated.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

[dogsx2]

looks like my contact was waaaaaaaaaaaaaaaaaaay off when he told me ES and retail should be similar

Whistling a different tune now?

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

ROFL heheheh

yeah i posted the first G0 quad results with 4GHz+ 3D benches from my contact but was afraid it would be much better than retail

it turns out it is on par with "good" chips

err not sure i get this post

[EDIT]holy that was on 680i chipset >>>> LOL i now know what Forsaken means LOL >>> ERRR i'm on the beta testing program and required to have that in my sig but i'm no cheerleader man common now

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.

[Fuzzy_3D]

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.

Stepping? :/...

I've orderd 3 i hope of some of that pure luck.

Just try small FFT, I admitted my past experience with other CPUs was wrong,
it failed in a few minutes at 1.58V when stressing small FFT, raised to 1.62V, 30mins passed the dual orthos.

Also try dual orthos and prime95, no obviously difference, as both not failed at 1.62V

1.62V,@ 4GHz Small FFT 30mins dual orthos passed

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.

nice try TinTin!!!!!!!!

[CERO]

hmz so what is a better test for RAM: Large FFts or Blend?

[lowdog]

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.

[lawrywild]

Best idea is to run Small, Large and Blend if your going for full 24/7 stability. 10 hours each

[fallwind]

My quad runs about 5c hotter with small FFT compared to large. Plus if you look in the task manager you'll see that small FFT barely uses any RAM(because it fits in the L2 cache) while large FFT will use every available MB. So it's pretty obvious small FFT is more stressful for the CPU and large FFT for RAM and FSB. But they are not mutually exclusive. Failing large FFT does not automatically point to the RAM because the CPU is still working plenty hard. Same with small FFT.

When I OC I start with the highest CPU muli and run the RAM underclocked with loose timings and then run small FFT to test the CPU. Once the CPU OC is finalized I jack up the FSB and RAM and run large FFT to test those. After everything is OC'd I run blend mode overnight for a thorough workout.

Trying to determine lowest stable Vcore for 24/7 o'c on air - 8 x 401 passed >3H Prime95 small FFTs at 1.30V BIOS, 3.2GHz looks good enough for use on my unmodded P5W (stupid linked Vcore/EIST/C1E options) at default Vcore even with droop.

[TinTin]

Torture test your CPU with Prime95

http://www.playtool.com/pages/prime95/prime95.html

but anyway, practice is more important

[dinos22]

dinos22: not everyone does 4ghz tho.....pure luck.

after seeing this thread and other results on other forums i can tell you right now it isn't really THAT much of a luck

look at 3.6GHz stable results and you will see that most of these are stable between 1.37-1.41v at that speed

and then add 0.05v for every 100MHz OC and as long as your cooling can hold out you will be able to reach 4GHz with around 1.57-1.61v somewhere

i got one of these CPUs incoming tomorrow week 27
in australia we are buying week 27 and 29 and they are so far doing 3.6Ghz 1.4v
