Ok, so I did a little overclock to my CPU with help from Hyper 212 EVO and got some...nice? Temperatures, 70-80c, maximum with 1.235 V was 81c.
I tested the OC with Realbench and XTU read the temps with RealTemp and CoreTemp.
Ran the RealBench test for 15 min with 16 gigs, no BSOD, voltages were ok.
Ran the XTU test for 1 min, no BSOD, voltages were ok.
I don't really want to wait 1 hour to see if it crashes, can you guys tell me if 1.235 is ok for many hours gaming sessions? Or should I raise the voltages a bit.
And, are the temps ok? I can go up to 1.25 without them getting over 85c
I should mention that the GPU is integrated for now. HD4600.

Yeah, it sounds pretty good...I mean you can test it later, longer if you want. I'd go play some games though and test it out to make sure it works in real life situations. Just monitor your temps. Sounds like you got a good chip man.

I'd maybe run occt test for 5 min and make sure it doesn't crash, other than that you can test it out in games...just monitor your temps and if you do crash or freeze up or anything, then you'll have to tweak it again. If that's stable at 1.235 @4.7, that's a damn good chip. Mine needs 1.25 for 4.6 Ghz.


Set occt for CPU OCCT in the upper tab...large data set test mode. It usually will fail you pretty quick if your voltage is off.

Did a 15 minutes test with 1 min idle at beginning and 1 at end. No BSOD, no errors. Max temp was on core #2 84c, but it showed 84 for a milisecond then dropped to 80-82c and never got again in 84c.
How is it?

Played CS:GO for 60 mins (2 competitives), won them, no errors, no bsod, 100fps almost constant because it drops like hell when there's smoke (hd4600, you disappoint me).
Anyway, I could try to make it 4.8 & 1.24V , but that's another story.
Thanks again for taking your time to help me, have a good one.

No problem bud and sweet, that's really good low voltage for that overclock...enjoy...next step is to get a good gpu for that nice I7.

You could probably get to 4.8 and maybe 4.9 and stay in acceptable temps with the hyper 212, or else you'll need water to get higher. My 4.7 is at 1.33 and it gets around 68 while I'm gaming and I don't like that, or I have to turn the fans on full and it's kinda loud.
