Is my 3570k overclock alright?

Hello, a few days ago I got my first custom liquid cooling loop installed. So I spent the day today messing around with overclocking my 3570k to find the best 24/7 OC I can get.

I ended up with 4.6ghz @ 1.280v using set voltage (I have yet to try and figure out how to translate that to offset voltage.) I ran prime95 for about half an hour running the small FFTs to try and push my temps up, and it only got up to around 87c as my highest temp during that test. I then ran prime95 on blend test for almost 5 hours. During the 5 hours I was running blend test the highest temp recorded on one of my cores was 89c.

I did notice that I had 1 WHEA error about 2 hours in to my 5 hour blend test run. After ending the test I have been using my PC doing things I normally do for about an hour now, spent some time browsing the web, watching youtube, and played a few games and havn't had a single problem.

Is this 1 WHEA error reason to tweak my settings any more or should I just consider it a stable overclock and carry on? won't be much of a problem to bump up my voltage another increment or two if that is what I need to do. Just want some thoughts and input from some more experienced overclockers.

I think that's what was happening on my i7 as well. Anything after 4.6ghz was setting the voltage way too high. I think you would be safe testing it again under a vcore of 1.30 to see if you get no errors. Just make sure you set the voltage manually in the bios so it doesn't automatically bump it to 1.32. My MSI mobo's bios oversets the value I set manually by .10 so setting the voltage to 1.29X should bump you up to 1.30 range if it happens the same way on yours.

I don't know anything about WHEA errors. Personally I determine my cpu's stability by ideal circumstances, and perhaps a 10-20 minute stress test at 100% usage.. since rarely the cpu's will see max load for 2-5 hours at a single time, but that's just me. I use AIDA64 Extreme.

Yeah that's pretty standard. My i7 4790k is stable at 4.6ghz but at 1.312vcore. Won't go any higher than that. For some reason it wasn't taking 1.28v so I just upped it a bit and it did the trick. I had 4.7ghz for a bit but decided it wasn't worth the potential unstability and just backed it off. With your liquid cooling I would expect you to reach 4.8ghz but under circumstances the chip can only OC so high under the rated voltage. It took some fighting for me to get past 4.5ghz for a while but 4.6 is still a solid overclock.

My temps under 100% stress load are 57°c min, 64° max with hyper 212 evo. While gaming it's in the 40-50's. While idle 25-28c.

I decided not to go beyond 4.6ghz. I was able to hit 4.7ghz stable at 1.375v but I didn't like having the voltage that high (not to mention that skyrocketed my temps up to the high 90s).

I am happy with the overclock, any extra free performance is a + in my book. My main concern with it was that I got that 1 WHEA error while running my prime95 test for 5 hours. To be honest I know nothing about WHEA errors, only that people say that if you get them you are not running stable. I am more or less wondering if I need to bump up my voltage just a tad more and stress test again because of this one WHEA error or if I would be fine just leaving my settings as they are currently?

I decided to go ahead and bump the voltage up another .010 and let it stress test over night. I just came to check on it and the highest temp was 88c and I had no whea errors. So I am going to call it good enough.
