Overclocking the i5-3570k ASRock Z77 Extreme4

those temps are alright, but try working down from the auto number until you hit instability

Will do, after i found the voltage number , ill post another load test.

The Ivy Bridge cpu is noted for temp problems once you start adding voltage in the higher speeds. A good cpu cooler will be needed once you get past 4 ghz. This article might help.

Currently, im on hyper 212 evo, my curren oc is 4.2ghz and 1.2v. Its playing battlefield 3 multiplayer no lag whatsoever with 60 fps no dropping. Its highest was 67c. Im pretty happy now.

What video card do ou have? The biggest difference maker in gaming is the video card and while the cpu can be a bottleneck at times it's best to have it runnung at a good high speed to avoid that. Anything over 4 ghz will do and then for more performance the video card can be overclocked to get even higher fps.

I'm using the Hyper 212+ and I have my CPU @4.4ghz and 1.29V and it's stable. However, if I try to adjust my GPU at all I run into problems? Should I reduce the OC on my CPU to give me more room to OC my video card?

I'm running an XFX DoubleD 7870 at stock right now. If I OC that at all under the current CPU settings my PC enters Power Save mode within about 5 mins of gaming. No overclock and the computer will run all day, so I"m suspecting not enough voltage?

I did experiment with upping the voltage to 1.35, but was still running into the same problems. BTW, my temps are fine. I want to OC the card, but not at the cost of not being able to OC my CPU at all, any suggestions?

Yes instead of hijacking someone else's thread you should start one of your own.

Im going to have the same equipment soon, should i choose the 212+ or the regular one?

So 1.2V is working well for a 4.2Ghz OC? Your original photo shows 1.12V, so was that the BSOD issue?
