Maybe the problem isn't the CPU vcore. I increased my PLL by .05v too.

I've got 6 1/2 hours now in Prime95 27.7 blend with both error checking and 7200MB max RAM. 4.6Ghz, 1.25v in BIOS. 1.55v PLL. All other voltages auto. LLC on 2nd highest.

Does anyone really see their temps fall with low PLL volts? I do not see any difference at all on this system (1.45~1.80v). Always 83~85C max on core 2.

Has anyone tried disabling the iGPU and see if that helps temps?

I disabled my iGPU, seems to help idle temps a little, not so much on load temps.

I mean if you don't use it, might as well disable it

Ok thanks will disable mine... i don't use it... haven't tested Virtumvp as yet though...

New here, been out of the game for about 6yrs now. My previous computer was a C2D E6600 OCed @ 3.2GHz, nothing crazy but it served me well.

Anyway, I just put together my new Ivy Bridge machine, once I made sure everything was running I went into the bios, followed the IB OC guide here and went straight to 4.5Ghz, which is my 24/7 goal for this machine.

Currently at 4.5Ghz with a 1.20v in the bios.

I'm running Prime95 v27.7 right now and so far so good, it's only been about 1hr but nothing has crashed or stop. I just ran the blend test, what should I be running? how long should I run prime before I consider it stable? anything else I should do?

Here are some screenshots.

375

Right now i'm using the iGPU until I get a new video card.

Also, anyone notice that their Core #2 temps are higher than the other cores?

@4.5GHz and 1.20v in bios getting 30-40deg C idles and it reached a max of 75deg C on core #2

Ivy Bridge i5 3570k owners at what voltage does heat become your enemy?

I have a Antec 920 LCS and want to hit a 4.7GHz overclock stable but without the extra fan noise to cool off higher load temps. Is fan noise a big issue when overclocked under load?

When using Antecs Vchill cooling software: I set higher fan speeds for P95 Small FFT's, so high temps won't make it crash being under full load.
My current sig rig under full load will hit 50C in a 70 degree room fans running at 2000rpm in P95. Fans can peak at 2400rpm.
In BF3 its 48C in a 70 degree room and fans running at 1600rpm this is better all the time since cpu isn't under full load.

I read somewhere yesterday that lowering PLL doesnt directly lower temps but possibly allows you to use a lower vcore, someone was stable at 1.75 another person had to lower to 1.7 from 1.75, or visa versa so it might not be linear.

Here's my final comparison on Prime95 27.4 vs Prime95 27.7 due to the advanced AVX FFT lengths that are harder on the processor. SUM(INPUTS) error checking and Round off checking are enabled. Blend test selected with maximum memory set to 7200MB (800MB for windows).

Bare minimum settings for 12 hours stable with above settings:
v27.4 - 4.6GHz @ 1.23v, PLL @ 1.5v
v27.7 - 4.6GHz @ 1.25v, PLL @ 1.55v

Ok messed with my settings some more. Dropped my vcore by .05v.

Running Prime 27.7 with small FFTs, about 30mins in, so far so good.

4.5GHz @ 1.15v in bios, PLL @ 1.75v

Highest idle temp of 34deg C
Highest load temp of 76deg C
