Then maybe stress a bit with OCCT test or Prime for at least a few hours and you should be good.

Well. I have one more question. In IntelBurnTest, and it doesn't matter how I setup it, under stressing it starts throttling and temps are around 100°C, so I guess even that it passed that tests in IntelBurnTest... Can I count on it, that is "stable?" I think I can't if it throttle, or am I wrong?

BTW: I will run Prime95 it is okey with tempst, but what torture test there for stability? Small FFT, in-large FFT, or Blend test?

This is my AIDA64 snapshot after 14 hours of stressing wink.gif

Wow, that is hot. Yeah throttling will mean it isn't getting stressed as much as you want it to. I get temps in the high 70s low 80s with IBT. Use the Prime blend so it tests CPU and RAM at the same time. The temps will jump though when it switches from small to large. If IBT is too hot you can use OCCT Linpack test, that should give you lower temps. Just don't check the AVX box. I actually prefer OCCT to Prime but I use Prime because it seems to be a "standard" here for stability.

Okey, I will do it. I have also last OCCT version. So I will try that. I'm happy, that it passed AIDA64, but as you said, and as I read is not sure with AIDA that it will be stable.. Thank you again. wink.gif

if I overclocked like 4.5 @ 1.25v , 4.2ghz uncore @ 1.24v but on prime95 it reboots. does it mean that uncore voltage is low or vcore is low.

Yeah, Aida is misleading and I found out the hard way, so I'm only stating my experience with it. It may be ok for lower multis (4.2-4.5) but it was way off for 4.7 and 4.8 on my system. My theory is that most chips have a sweet spot that will take predictable voltage steps until a certain point. In my case it is 4.6, and anything over that requires much more fine tuning to get stable. Although I can boot at 4.8 (and even pass Aida) it requires a serious voltage step to be able to run other tests. So it is good to use different tests to see where you are at. Like I said before, I don't like to tell others how to gauge stability on their system because that would be hypocritical of me, but Ill share my experience and let you decide what is best. You have a good chip there so be careful with the temps while stressing, and don't go crazy if you don't have to.

I have one more question. About the Voltage. I mean Vcore.

I set it on 1.260V.. CPU-Z and HWinfo64bit shows 1.261V, that's I guess normal. But I'm little bit confused from HWmonitor, version 1.23.

It shows on Vcore in load 1.280V, why is it like that? Is it mistake, or is right like this? It shows also my set 1.260V but on VID. Can you explain it to me? or somebody? What is right? Thank's.

I'm trying non AVX Prime95 - version 25.11, then I will try the last version...

Probably Vcore. Easiest way to check would be to reset the uncore to 36x while leaving the core pseed the same and see if it still does it.

Are you sure you are looking at Vcore in HWInfo and not VID? Vcore is usually lower down on the list - the one up at the top is VID. CPU-Z normally shows VID (or really, just whatever you set in the BIOS). It's not unusual for the voltage to be a little higher under load than what you have set - I've seen mine bump up +0.01V before, even in manual.

I set the uncore speed to x36, do I set the uncore vcore to auto or something else.

You can either put it at Auto, or leave it at something conservative like 1.15V.
