Can't push my i5 3570k past 4.4 ghz!

tadeuty · Jan 28, 2014

Hey guys!

I have an i5 3570k that's overclocking nicely at 4.4Ghz right now, but I want to push it to 4.5. I have an H90 liquid cooler on it, so temps aren't an issue. I think it has something to do with increasing the voltage, possibly vcore voltage? However I was wondering if there was anyone out there with similar specs that can tell me what voltage to use and if they have the same motherboard how to adjust vcore, because right now all I see close to that is VCC.

Here are my specs:
CPU: i5 3570k
Mobo: ASRock Extreme6 Z77
CPU Cooler: Corsair H90 (140mm radiator)
PSU: Corsair RM650
GPU: Gigabyte R9 290
RAM: DDR3 1600 mhz

What?

Nevermind i thought it was just your signature.

tadeuty · Jan 28, 2014

So when you set the CPU voltage it was in fixed mode, not offset?
Thanks for the quick response!

Fixed.

I have the exact same setup as the guy above except my 3570k hits 4.5 @ 1.25 volts fixed.

mradrian :

Its still causing windows to blue screen for me

tadeuty · Jan 29, 2014

I have tried both 46 and 45 at 1.25... Bad CPU?

chrisso · Jan 29, 2014

Sr71 is set at 1.288v

lewisaro1 · Jan 29, 2014

im in the same boat as you, for 4.5 i have to go to stupidly high voltage but 4.4 is stable for me at 1.3v

mradrian · Jan 29, 2014

What C-states do you have enabled? A picture of your BIOS settings would help

tadeuty · Jan 29, 2014

Ok I'll post pics later.

tadeuty · Jan 29, 2014

Here's some pictures of what I have in the UEFI.

Try turning additional Additional Turbo Voltage to the lowest setting possible and turning off speedstep. If still getting BSOD the turn CPU Load-Line Calibration to Level 2.

Ok I'll try that tomorrow, thanks for the help.

tadeuty · Jan 30, 2014

I kept blue-screening. I actually had to clear CMOS because the uefi was freezing up

tadeuty · Jan 30, 2014

I think I'm just going to stick with it at 4.4 Ghz

mradrian · Jan 30, 2014

Yeah probably not the best OVC'r you got there. What voltage are you stable at for 4.4?

tadeuty · Jan 30, 2014

If we are defining "stable" by whether or not I can play Battlefield 4 with it for extended periods of time, then right now its stable with an offset voltage of .020V, and it performed about the same before at .015v

Can't push my i5 3570k past 4.4 ghz!
