Installed my 4770k on saturday, seems a bit hot at stock. I used HWmonitor to measure temps and ran 20 passes on high for IntelBurnTest and max temps were 80c, 8 hours of Prime 95 and the same max temp of 80c. Idling temps are around ~30c. Proc seemed to only handle 2-3 passes on IBT's very high setting before the "failure" message popped up.
I want to OC to get a stable 4.2ghz at some point, but I'am thinking that the Noctua NH-U12P I'am using will be too hot? Tempted to try a Noctua NH-D14 as I would rather go Air than the close loop water cooled option (too many horror stories puts me off).

its a cracking bit of kit for the price i paid(£145)!!! no issues to report as of yet, i'm currently working on 4.8ghz vcore 1.363v, CPU VRIN 2v (extreme llc), 43ghz uncore, cpuring voltage 1.27v, ram @ 2400mhz 1.65v sa 0.100v, i/o A 0.100v i/o D 0.100v.
seems pretty stable.. getting 10.57 on cinebench comparing to my i7 3770k @ 4.6ghz i was scoring 9.36.
chip needs delidded, in cinebench after 30runs i'm hitting 86c on highest core. cpu batch number is L316B in case any 1 is wondering.

I recently got my i7 4770K with a Gigabyte Z87 D3HP board, I am not interested in pushing my chip to it's limits, but I went into the BIOS and set the frequency to 40 instead of 35, leaving everything else the same/defaults.
This gave a mild overclock to 4Ghz. Without stressing the hardware or upping the voltages, is it a good to just leave this like this and get on with things?
I figure a bit of free extra performance is nice, but I don't want to be messing around with it too much or getting random BSOD's or anything.

Away to hit the sack after being at it all day. Currently sitting at what's below, delid on air. Custom W/C on route but temps are still quite decent for now.
An hour into XTU stress as well, only 8hrs more to go!
Benches done with RAM & uncore at 1333Mhz/x34. (still playing with core so not even got round to uncore/RAM yet!)

Can't see any clocks there mate, the picture is wayyy to small. 
Phanteks with Thermalright TY147's and a de-lid. W/C setup should be arriving tomorrow. Not really needed for the cpu but the 780's are scorchio and i'll be flashing them to run higher voltage so water is a must. Just a bonus i'll be able to drop temps on the cpu as well.
That XTU run managed the best part of 8hrs before crashing so just a little tweaking needed!

I find XTU good. (or IETU giving the proper title). It has both a stress test utility and bench utility. The bench option uses AVX just as P95 27.9 whilst the stress is AVX free.
I tend to use Cinebench render 1st as a quick check, if it passes that then i'll do the XTU bench. The XTU bench i've found is a good indicator of how close you are to being stable. If it crashes then you know you need change something boldly. If it drops cores but passes then you only need some tweeking. Does help to give you an idea of where you're at with the O/C.
Once that passes no problem then i'll use x264 and run the full 4 runs/8 passes. This is a bit more of as real world AVX test. Final check i do with XTU stress which i'll leave running overnight. Anything around the 8hr mark is solid from what i've seen. Played BF3 this afternoon for an hour or two and no problems. Might be a different story with BF4 though from what i've heard!
I used to use P95 (27.9, not 28.1) but not a fan anymore. I found doesn't really give you an idea of what's going on with the O/C and requires more voltage than what you need the computer for.

Have had no problems at 4.5Ghz at 1.2 volts but Battlefield 4 beta did completely lock up once (on the results screen of a game, lost all my progress in that 40 minute match!)
Might be unrelated of course...

Replaced my Noctua NH-U12P with a NH-D14 today, with a 3 fan setup.
After some playing today, all I could manage was:
4.2ghz
1.25v vcore
4.0ghz Cache with 1.2v
Input voltage 1.9v
Its been stable at prime 95 for 4 hours, But fails IBT. Max temps of 82c.
Soon as i tried 1.25v at 4.3ghz it would BSOD after 10mins of P95 but pass IBT. 4.3-4.4ghz seems to require 1.3v sometimes just to boot, tested it on IBT and it passed but was hitting 92c. Really I'd like to keep temps down below 85c even in synthetic tests, probably unlikely to happen with this chip on air.
Temps just seem to spike after 1.25v on my chip. Does anyone else's voltage increase by 0.016v over what is set manually in BIOS? For example if i set 1.25v it will go onto show 1.266v in CPU Z and HWMonitor.

This 4770K I'm running at the moment is stable at 4.5GHz but I can't get it to work at 4.6GHz. Temps aren't an issue, and it's a decent board (per sig). The thing is, it's stable at 1.30v at 4.5GHz. I tried 1.35v, even 1.4v, and it crashes immediately on any stress test.
The Gigabyte board has no LLC setting for vcore.
Any ideas?

Not right, tried flashing the BIOS to whatever is latest at Tweaktown?
I've got the latest BIOS on the Gigabyte site.
