4670K needs help with OC

[Oeufcocque]

I recently attempted to do overclocking on my 4670k, and came across the magic number of 1.25v vcore, 4.4ghz on several guides and posts.

I tried OC ing on XTU, and then doing stress test for 8 hours and also benchmarks 6 times, all on XTU.

The config passes all, with highest temp of 82C

I'm overjoyed, and I'm ready to play Dota 2 again, which shouldn't even require any of the OC.

 

It crashes after ~5 minutes in, and the XTU set the config back to default, which works out fine when playing Dota 2..

 

I currently use GIGABYTE SNIPER M5 mobo, 8 gig of ram, and 4670K, with my GPU is currently being repaired, so I'm using the onboard graphics

I read numerous Q&A about whether onboard graphics will interfere, and each one of them says it shouldn't.

 

So my question is:

1. is intel's XTU unreliable for OC? should I go only for UEFI?

2. is 8 hours of stress tests and 6 benchmarks on XTU not enough? how far should I go?

3. is this issue lies on any other possible problems? I only OC the CPU, I even let the RAM stays at default without XMP

 

Thanks in advance

I'm not so experienced with XTU to be able to have opinion on it. Its still software and may have bugs which have effect on results. But since you have found working settings with it, you should go to BIOS and dial them in manually. I would also suggest using two different programs to validate OC. So if you use XTU, use Aida or OCCT as secondary. Different software stress system bit differently and may find some things where system isn't as stable as you thought. For this happened when I first tested with Intel Burn Test and when that passed, got crash in 5mins with OCCT.

None of the tests are 100 percent reliable. I will usually run a few minutes of prime blend,  AIDA 64 for a half  hour, a 3d mark vantage, a couple passes of Asus Real Bench, a cinebench r15.

 

Games are simply the best test though (as you found out). You can go 8 hours in AIDA and crash in 3D Mark or the other way around, or a full day and crash within minutes in a game. There is no real fool proof way to test. Some games will crash fast with instability. Planetside 2 does in my experience. 

 

I say run a 45 minute to hour session with a bunch of tests and game. 8 hours, I wouldn't mess around with, without water cooling. No reason to stress a CPU out at mid 80's C that long, in temps it will never see.

Thanks for the replies!

 

I think I somehow cracked it, windows pagefile starts using my empty partition, and after disabling pagefile, no more issues detected.
