And how long have you been running it like that for? 1.44V is rather extreme. Too extreme to be honest. Really curious...
1.44v on a X5650 @ 4.3 at 60C steady on air using Prime 95 blend.
That's nothing, some have been running their CPUs at 5V for 28 years :awe:And how long have you been running it like that for? 1.44V is rather extreme. Too extreme to be honest. Really curious...

Ahhh... These must have been awesome times, when you wouldn't let a few volts get in the way of you and glorious performance. As glorious as 20-40MHz could be, anyway.
Kinda like the middle ages were awesome times. Except not really.
Just curious ,which CPU test do you run in OCCT , the OCCT CPU one or Linpack one .Am I the only one that is afraid of leaving my CPU running stress tests overnight? Not necessarily overnight, I'm just afraid of leaving it there running at 100% without my presence in case something goes wrong. I mean, during Prime95, my CPU produces enough heat to overwhelm my H110, so it will rise to over 90C (sometimes hitting 100C and throttling) after about 30 minutes of testing. OCCT/x264/AIDA64 are lighter on the thermals, but I'm still afraid to leave it.
Generally, my way of testing involves opening any monitoring software I need, starting the testing (usually OCCT because reasons), opening my music playlist and leaving it there. I don't watch it or do other things, but I know it crashed if the music stops playing. Not the best way to do it, but I am at peace knowing that if anything happens, I'll be there.
Am I too paranoid about it?
One can say a lot of bad things about AMD CPUs, but they can handle some voltage alright! 1.35V isn't even close to too much for Piledriver overclocking.FX6350, 4.2Ghz, 1.356v according to CPU-Z.

If you enable AVX option it gets pretty hot to ,very close to prime95 latest version .

I use the OCCT test. The Linpack one, especially with AVX, kills my thermals within seconds. We're talking about hitting 100C before the fans can spin up! On Haswell CPUs I wouldn't use it without custom water cooling, to be honest.
A long Time.And how long have you been running it like that for? 1.44V is rather extreme. Too extreme to be honest. Really curious...
Really? I wouldn't worry about the board if it's high-quality. I'd be more worried about the chip crapping out. Still, impressive!A long Time.
P6T7's are pretty good boards to begin with for handling things I guess.
I think I even had the I-7 920 in here kicked up a lot for 5 years, but it's elsewhere now.
Ok, The OCCT test for me is about same as prime95 (ver 27.9) I do about 63 or so after few min . The Linpack with AVX goes to about 70c for me after few min . I don't use it for testing .
I am at only 4.3@1.135v so temps not up there .

Yup, OCCT yields similar results to Prime95 27.9.
I've been using Prime95 28.5's large FFT test lately trying to overclock my uncore. With every setting I've tried it crashed sooner or later. Even 3.8GHz at 1.15V. Other settings crashed within 2 minutes, others took over 15 minutes to crash, but eventually everything crashed. The 4.7GHz at 1.307V core/4.4GHz uncore at 1.21V I'm using now doesn't even make it to 3 minutes in Prime95 large FFT. Strange thing though, it passed 2.5 hours straight of Aida64 stress test (CPU, FPU and cache selected). I think that's stable. I'm gonna give it a week or so of daily usage and see how it goes. If I get no instabilities, I'll try encoding a large video file with Handbrake and see if it gives any errors. If it doesn't, and it passes 2 hours of OCCT and x264, I'll call it stable and Prime95 can be written off as useless for me.
hmm , should not crash at stock clocks with defaults in bios .
Have you tried with lower clocked/loose timing on mem (not XMP ) , might be a flaky stick .
See how Realbench works , that is a bunch of real world apps bundled up for test (gimp, handbrake , luxmark etc )
My laptop has a i7-4700mq in it.
Dynamic CPU voltage offset is at -116 mV.
Processor voltage offset is also at -116 mV. (ratio slightly lowered).
So my CPU at:
idle @ 0.56v (800mhz)
load @ 0.93v (3.1ghz) (4cores stresstest in XTU)
how do those relate to end voltage , I am on IB so no dynamic cpu voltage . whats total - offset and final voltage ?
Yup, AMD CPUs like their volts high. My father has an Athlon similar to yours (don't remember exactly, as it's in a soon to be retired rig) that unlocked to a quad core. Voltages were so high that I thought the chip was defective. It stopped being able to have four cores enabled after a point, but it's still running in tri-core mode. Voltage is close to 1.4V for something like 3.7GHz.1.368v, which is stock for my Athlon II x2 unlocked to a tri-core. Currently at 3.6 ghz. It takes something like 1.48v to get it up to 3.9 ghz.
1.376 at load on a 3770K@4.6. temps are low 70's, so I'm ok with it. Had it for about a year and a half.
