Guys,

I'm looking for a simple overclock for my 4770k. I'm running a Gigabyte GA-H87-HD3 mobo, Kingston Predator RAM (8 GB, 2400 MHz), Corsair H60 v2 for cooling duties with two SP120 fans running push / pull.

Stock speeds I can run the CPU's (2-8 hours solid) at 100% around 65-68 degrees.

I have been trying to dial in a small OC to 4.2 GHz. But the computer seems to either freeze, or I get the BSOD.

Now when it freezes, I think it's probably overheating, too much voltage?

When it's BSOD, is that likely not enough voltage?

My mobo doesn't allow for lots of configuration, so I leave most settings stock on auto. I have the multiplier set to 42, and voltage to 1.16 just now. Am about to try another stress test (video encoding).

Is that really too much voltage for this relatively small OC?
 
Yeah, the RAM I just picked XMP Profile 1 and left it.

Even with a relatively small OC of 4.2 GHz with voltage set to 1.25 and it's unstable, and the CPU heats up pretty quick too. Then Windows either hangs, or BSOD. Even knocked th OC down to a multiplier of 40 and still the same.

I test the set-up simply with video encoding in Handbrake, as that's what I use the machine for, so it maxes out the CPU almost instantly, and takes anywhere from 1 - 2.5 hours to do a single file.

The last few days, I just loaded optimized defaults and ran it. It Turbos to 3.9 anyway (although down to 3.7 when encoding), and maxes temps at 68 degrees.

I figure if I do want to OC from here, I'll need to invest in a better mobo and CPU cooler, and, tbh, with having just spent so much on the rig, I don't have the heart to spend any more. There are a further 8 case fans BTW in the rig keeping everything relatively cool. I have 4 intakes (2 bottom and 2 front) 3 exhaust (on top), the 2 push / pull on the radiator at the rear exhaust (obviously set-up as intake though), and a single interior fan directing the intakes toward the general CPU area.
 
Must just be the worst 4770k ever then. Just not clockable. Might have to re-apply some decent thermal paste and re-test, but I just get no-where.

I tried your settings dougal1331, but the temps popped straight up to 87.
Then started reducing vcore, 0.1v at a time. Got it down to 1.17 where temps were still at 83, before the system froze, then BSOD (0x000000124).

Put it back to optimised defaults, temps still way up there at 82??? This is beginning to really bug my happiness now. I'm sure if I leave it a while (couple restarts etc...) the temps will come back down to a more reasonable 68 or so.

As it is, I'm pretty peeved tbh. Spent all that money on the "best" chip, the 4770k & The H60 v2 cooler (which I though would have been half decent at least), and can't even get a slight OC on it. Not entirely convinced a better mobo would realistically make that much difference.
 
I have the radiator fans full pelt. ~1350-1400 rpm.

As suspected, left the PC off overnight, and after booting it up here, and loading up an encode, 4 cores maxed at 100% sees temps of, 68, 69, 63, 54. At least core 4 is nice and cool.

What is tim? Is that the thermal paste?
 
Yep, that first one was the one I was going to get. I had a read of Stulids reviews, and figured as it was the best performing, that would be the way to go, and to hell with the difficult application.

The other two look even more expensive though. Any comparisons to the Coollaboratory stuff? The Gelid got ace review from Stulid, but at £20?
