Help with 5820k overclock.

post #1 of 10
Thread Starter 
I've been running my 5820k for a couple of days at 4.2ghz, tried 1.28-1.26 vcore but i'm not getting any luck with using OCCT because the temps always go over 85c with the small data set test. That's with a NHD15 cooler, i can't boot with volts lower than 1.26.

So i'm not able to stress test properly even with these voltages, Aida64 ran fine for 11 hours but it isn't that stressful apparently.

What should i do now? Any good advice appreciated.

Delete OCCT. Use AIDA only as a program to check voltage etc, it's no good for stressing. Now that those are done, download Realbench (I think 2.41 is latest) or x264 from one of the Haswell threads here. You could also just use Prime 27.9 Blend or 28.5 Blend and disable FMA3 manually, if you don't you'll just create headaches for yourself.

Also XTU bench is another one, run that few times in a row and it's fairly stable if no issues arise. Don't run the stability test, it's as useless as AIDA.

Error- is IBT useless w/ Hasswell and -E now too?

Anything that uses AVX 2.0 pretty much cooks the CPU.

Yes I would put that in the same category, the programs mentioned earlier will cover you while giving you the temperatures that you may / should experience in normal daily use which is what you want.

Of course if all you do is search for Prime numbers then you'd stress with Prime..

Interestingly, my old 3570k was BSOD'ng as of late, stressed it with IBT, fine. Ran Solidworks benchmark and was BSOD on heavy render. I had to run the wattage up to fix it.

I ran IBT on my Haswell laptop and it just cooked it bad to the point it throttled.

try raising the input voltage at 1.9 volt (1.8 stock) and the cache voltage a little, it can reduce the necessary vcore needed for stability.


also i think that someting is wrong with your cooler because my temps won't go over 83 degree at 4.4 ghz(1.285V 5820k) with only a corsair h110(prime 95 28.5 small data set and occt small dataset)

Ok, i may have dived into it a bit too quickly. But, i ran Realbench for the 8 hour test, that went through fine.



Now, my ram on the other hand was not stable. I ran HCI memtest for a while and an error popped up with those settings/timings listed in the image above.

So i altered the settings of the ram and ran HCI memtest again with the settings in the image below.



No errors, at least not for the time i ran it. I don't completely trust it though, i play L4D2 often and yesterday it was closing to the desktop after only 1-2 hours, though that was with the 12-12-12 timings.. i mean it always did this before on all my PC's but usually only after many hours. Maybe i should use my computer a bit now and see if any of the changes have made a difference.

Are there any other tests i can run? Or is the only way to do it properly to let a test run for a longer time?

A couple of review sites had this ram running at 12-12-12-1t timings and they said without issue. I think the reviews must be inaccurate and they didn't test them for long enough.

I restarted and tested the ram in windows again, i got a BSOD as soon as the test started and the log has a bunch of errors.. yet it ran for hours before that. Can this point to bad ram or is the overclock/timings bad? I'm not sure whether i need to test for a long time at stock settings or not now. Some random/intermittent thing it seems like.

Is it best to put all the ram settings back to XMP and let the HCI memtest run for longer this time? Not sure what's going on but they don't seem fully stable even with settings recommended in some reviews, nor a little higher.

I think 4.2Ghz could reduce more voltage.
