I use AS5. Guess I underestimated IB after all, but people swore by this cooler and I believed them. Bah!
I'd get Thermalright HR-02 Macho, but I don't like how unflat its base is :(

Um, I have no idea what WHEA is. All I use for stability testing is Prime95 and there's nothing else I'd need.



Forgive Me, I did not notice the negative DVID, I assumed it was a +. Sorry.


In what way is the DVID high? I was testing all the way from -0.155V, currently -0.110 and still Prime disappears in around 3 hours. Temperatures are already past 90°. I don't get it at all.
I have no idea what LLC does, only know I should set it to extreme (the way I understand it, extreme makes the voltage more stable).

edit: keep in mind I use negative DVID, not positive. According to CPU-Z, vcore is already at 1.116V (not sure what the real value is, probably give or take 0.015V)

Oh.... Some of us find it very handy to use a few things in steps along the way. Prime95 for me is the last of the tests after getting by the first clocking steps where there are sure to be adjustments needed. To make a tweak and run Prime95 for several hours and then tweak again to wait another several hours..... every time I make an adjustment..... is painful.

May I suggest:

Familiarize yourself with Windows Event viewer in, Settings/Control panel/Administrative Tools/Event Viewer. Go there and select the top of the list "Event Viewer (Local) so it will show you a window similar to the screen shot below. Then expand the categories especially the Critical, Errors, and Warnings and see what you have. Now don't freak out on every issue, because there will be non-critical stuff there, just key in on WHEA's. If you have none have a beer and celebrate. But with those temps and that DVID, I dunno. I am a novice just trying to share.
What my mentor pointed out to me is if we have WHEA warnings in the list we still have tweaking to do before we can claim to have a stable build. My guess is you have them.

Do your first BIOS clocking and run Intel Burn Test on high and see if it passes. It does not run as long as Prime95 but if you have major or obvious corrections needed you will get a failure message. You can then make adjustments and run it again, all the while going back to Event Viewer in between to see if WHEA's are still being generated.

I always have a RealTemps window running and CPUID so I can monitor things.

After I get Intel Burn Test to run with success and no or very few WHEA's, I then run Prime95.

I am familiar with EvenLog, but I still don't understand what WHEA is, lol.
I don't have any special errors in the log anyway.


And btw, IBT is not good enough, or rather not as good as Prime95. I had it pass 50 loops without problems and Prime still crashed after a few hours.

Neither are if you are not running the most recent version. I would suggest LinX over IBT as it is updated more often. But both can be updated your self by looking for the newest Linkpack Libraries from Intel.

Also you want to make sure you have SP1 installed for Win7 to make use of AVX. Which will stress the cpu more then with out.

50 loops of LinX or IBT is way to may times, only max of 20 should be done at MAX memory.

[Octopuss]

Well, memory stability is not the problem for me anyway. SP1 is pretty obvious to have these days I guess.

I just need better heatsink, that's it. I could fry an egg here!

[Acebmxer]

My statment about using MAX memory was not necessarily directed at memory stability but more to cpu stability. If you run either LinX or IBT at 1024 mb the load time on the cpu is maybe 17-20 seconds. Where as the load time on the cpu when using max memory is 2-4 min and may require more vcore to remain stable.

[Octopuss]

I'll give it a go, nothing to lose here of course :)
I think updated version of IBT was released lately, too.

[2therock]

OK, WHEA will kind of explain when you double click on it. Mine always shown what cores were throwing them. Here is a link. When you said you did not need any thing else I did not know you had used IBT.

So, are you WHEA free in Event Viewer?

[Octopuss]

Aha. I see. I don't see anything like that in my log at all.

Testing-wise, I kind of only believe Prime95. Tried IBT and memtest in past, both weren't reporting any errors whatsoever and yet Prime was crashing. That speaks enough for me. Also the claims of IBT that it will produce more heat than Prime95 is laughlable. It's actually almost the other way around. With same bios settings Prime95=up to 95° on cores, IBT=80°.

[boondocks]

Well my newest 3770K cpu turned out to be a real dog, temperature wise. Even with custom cooling it's way hotter than my other 3770K. I had already lapped the cpu before I installed it, I won't make that mistake again.
Anyway I swapped my "old" 3770K into my new rig and it's running fairly cool for the vcore/OC it's set at, so I'm happy with my custom water cooling. I put the new cpu in my older rig and it still exhibits the high temps thus I know nothing else is at fault. So far it's made in Malay +1, made in Costa Rica -10.
