Core i7 920 rev D0 stepping 5 :)

Prime blend is harder to pass than IBT or Linx. Although 2 hours isn't much I have been through 3 different processors and 2 different sets of ram and have always needed 2 extra notches of Vcore to pass Prime blend after I was Linx stable. Also have spoken to others that have much the same results, however have never seen anyone post screens of prime blend 8 hours at the same vcore as linx. Care to take the test?

It is hard to make a global statement based on a few samples, and apply that to thousands and thousands of other setups, sometimes you can be right...and sometimes not. Took me just few hours with linx to find below OC points, and have checked some with prime, and like on my i940 I record tests.

4.2 HT on, vcore 1.28 pass linx 10 runs of 5100mb, 2 notches less fails 1st pass.

4.3 HT on, vcore 1.31 pass linx 10 runs of 5100 mb (max memory), 1 notch less failed 8th run of same, later confirmed 9 hrs prime stable blend.

4.4 HT on, vcore 1.34 pass linx 10 runs of 5100 mb, 1 notch less failed 6th run, confirmed later with 9 hrs prime stable. Lowered vcore 1 notch in bios, still says 1.34 cpuz load, and still passed prime 13 hrs.

4.5 HT on, vcore 1.38 pass linx 5 runs, 45 mins prime, did not run either longer 2nd temps.

On both my i940 and i950 I need at least same and when tested more vcore for linx at max memory, than prime.

Showing a prime blend and linx stable screenshot together, how would you know they did not simply choose a vcore that both would run at I have a 13 hour run with prime blend at vcore that failed linx max memory.

Only way to prove anything would be to video a 13 hour run of prime at vcore where prime passed but linx failed, then keep video going and run linx and capture the bsod. But time demands vary considerably from my interest in the subject.

Since I have now heard quite a few arguing both ways, I assume it is possible for some cpu/mobo/setups to need more vcore for linx or prime, especially given difference between 2 programs and given extra heat of linx.

Or maybe I should get into the internet spirit, and say everyone is crazy that found it the opposite of my setup.

Just starting to overclock my W3520. Stock voltages, but boy these things can get hot, even under H²O.

LOL I know I pull my hair out every time I see someone claim you can't pass linx when you have a Prime blend stable 8 hours or more. It drives me crazy because it has never been the case for me Linx is rough on temps but easy on stability it is roughly equivalent to Prime small FFT's in my experience and that's with 3 different processors and 2 different sets of ram. Also 2 different mobos... It's not that I don't believe anyone It's just that I would love to see some screenshots showing otherwise to satisfy my curiousity because in my experience I just don't see how it's possible and i've never seen anyone post screenshots saying otherwise so I continue to believe it's not possible.

I don't think this debate will ever get solved though even with screenshots, because there will always be people to claim otherwise

+1 on this. I can run prime Small fft's for 12 hrs at 1.32vcore just like linx 20 passes but when I run prime blend I need 1.34v for the same 12 hrs run.

for prime95 guys use custom blend or large ffts with 5400mb allocated probably best settings for testing but still fo rme linx and even hyper pi 8x32m might need more vcore than prime95 for SOME cpus not all from my experience with 4x i7 920 c0 and d0 and w3520
