A VERY Stubborn 4770K

post #1 of 32
Thread Starter 
Hey everyone,

I'm having a 'trying' time trying to establish a half-way decent overclock on my 4770K

HARDWARE:
Maximus VI Formula
Corsair AX860
Corsair Vengeance 2x4GB 1600
Corsair H105
Corsair Air 540

To start, my system will run at stock settings +XMP all day long, doing whatever I want, without even the slightest protest. Stress testing and gaming at these settings is without drama

This all comes to an end the instant I try to overclock.

Starting Settings:

CPU Multi: x42
CPU voltage: 1.2000v
Uncore (Cache) Multi: 34
Uncore (Cache) voltage: 1.2000
Strap: 100Mhz
Memory: 1333Mhz
VCCIN: Auto

These resulted in instant BSOD during Windows boot. I have fiddled and fiddled some more with these settings one at a time and yet I cannot get anything resembling stable without boosting the CPU voltage to 1.275v and VCCIN to 1.8v and even then I am getting BSOD after a minute or two of Prime95

Temps are well within acceptable limits. Heck, the thermostat here is set for 60*F and the H105 seems to be doing its job.

I have ready through the various guides including the Haswell-specific one in this very section.

Is it possible I just have a very doggy CPU?

Are you missing something, a setting perhaps?
4.2 is very low to not be possible for any CPU... heck even my i7-750 could do that easily.

Read the Haswell overclocking guide with statistics here on OCN.

You probably don't want to be using newest version of prime blend. If you'd read that guide, you probably wouldn't be using it~

This guide is great. Really improved my Haswell overclocks.

I've read through that guide and also followed the RoG guide to the letter. Same result.

Obviously I am missing something. I can't believe that I have managed to find the most lethargic 4770K on the planet.

That's weird, maybe you could try to work from the beginning. If you can get 4.1 stable but not 4.2, you will have an idea how much voltage is needed and be able to look for something else than that.

Don't bother to test more than 10-20mins you are not looking for the absolute stability, so it's not that long to slowly increase the voltage and get to the desired speed. I do my tests with linx on lynnfield and sandy I didn't need more than 10 mins (more often I would do 5 mins) to check if the system is bare minimum stable.
In my case I could do prime for 4h and it would come with nothing but 30 mins linx wouldn't pass... Since that day I never used prime again.

You've read through it without trying the recommended stability test?

TBH Somewhat likely you've got below average chip but up to date version of prime or linpack on Haswell is a little nuts. It's hard to know for sure, partially because of how nuts they are there is little data for comparison.

Bumping the CPU voltage to 1.225 as shown in the screens above looks to have made a difference. Prime95 is still hanging in there. Obviously it's way too early to tell but it's a definite improvement.

Wow though...that's A LOT of CPU voltage for that overlock...

Prime95 25.11 btw
