Vcore = 1.235V: had crashes after 1hr while I was sleeping

Vcore = 1.24V: instant BSOD

ENOUGH! I reinstall Windows, install just OCCT and TeamViewer and AISUITE so that I ca stress test from work.

Vcore = 1.24V: crashes within minutes
Vcore = 1.25V: crashes within minutes. Last night it went on for 1.5hrs without a crash.

But sandy bridge is so easy, you'd have been done long ago.

Look at all the fun you're having here! biggrin.gif

Man you are so lucky you weren't near me! You would be headless by now.

I need Steamroller! Don't care how slow it is! At least it won't be a pain in the @$$.

I've seen similar behavior where it is fine one day, then fails the next with the same settings. I think it may be temp related - if I test at night I seem to have consistently better results than testing in the afternoon/early evening, even though the reported core temps are only a few degrees difference. Of course I tried running my radiator fans full speed to bring the temps back down in the afternoon and it still crashed, so who knows. Maybe it isn't the chip temp that is causing the problem but something else on the motherboard that is getting hotter during the day. Maybe I should point a fan at my RAM or something.

I thought about that as well but my temps stay remarkably similar throughout the whole day, it has to do with where my computer is in my house. Plus, I've crashed under chess at night before, where it is the coldest in the entire house.

If it's not CPU temp related then I should crash much more often gaming than chess as gaming puts heavy load on the GPU and it starts spewing out hot air in the case. That's not the case.

 

BTW, been playing BF3 last week, seems as stable if not more stable than Chess for me so...

 

 

If there is a correlation between say, hitting 75C vs 80C and crash vs no crash in temps variance like that, then the correlation isn't strong enough for me to pick that up.

I feel exactly like you. This used to be fun, now it's just like Haswell is torturing me. I have worked on this for so many hours it makes me feel stupid for wasting the time. I've tried every variation of every setting possible. I partly blame this newer version of prime95. I used to believe I was stable at 4.5 with 1.3V and temps under 90C. With version 28.1 I'm now at 1.25V for 4.3 and temps hit 97C max. Intel burn test and AIDA64 are a joke compared to this. Seriously thinking about a delid now. Prime95 28.1 may stress it a bit un-realistically but I want my OC'd chip to be able to pass the same thing it could if it was stock. Just an anal thing, I'd feel like it's somehow crippled if it couldn't.

When asus said 70% could reach 4.5ghz, at what voltage were they talking about? I'm trying to do 4.4ghz and I'm still not stable at 1.3v. I have a feeling that I have a very unlucky chip. Temps with h100i reach 92 with prime95 at 8k fft but 59 with 448k. I don't know if my replacement h100i is another dud or if it's my cpu.

Try reseating. Or try lapping if that doesn't work. They might not be touching very well, you might be using too much thermal paste. Make sure to eliminate user issues before moving forward.

I'll try reseating (again) and try to use (even) less thermal paste. Not going try lapping though. But is my cpu a really crappy one if it requires so much voltage to do just 4.4?

Depends on what version prime.

And yes, you chip is below average. Average seems to be my CPU, 4.5 at 1.28v.
