ah, this is the ROG board guy from a few pages back. Yeah, 1.355 is not too high for a 2600 like you say. It should be down around 1.28-1.3 @ 45x. My 2700K needs 1.328 in bios for 46. I'm not too familiar with the ROG bios...

On your electric bill? Not much. Idle watts are very low especially with the idle states in today's CPUs and GPUs. Its green.
I really don't like sleep states with my water cooling stuff. I'd rather shut down. a reboot takes about 30 sec: Capture.JPG 140k .JPG file

It is actually 4.5.

I took the screen shot a little late after IBT finished. Max temps were 77-85-84-74.

I might change my PLL to 1.75 again. Last time my temps were about 3-4 degrees lower with it enabled.

Yep srry im running prime at the moment but those screen shots from before (on page 342) are my exact settings except for the raise in vcore. So do you guys see anything wrong or anything i could change? Temperature is not a problem i have a h100 and it keeps temps under 70 so thats all good i just want to get the most out of my pc smile.gif

Sounds like you are real close! please fill out your system spec in rig builder
Untitled.png 501k .png file

I do believe I've fixed it - it was a power limit on auto (specifically the turbo boost power limit!)

I haven't finished yet, however currently I'm at:

Currently an overclock of 4500mhz (x45)

Idle Speed/Voltage/Temp:

4500mhz / 1.04 / 29degc

Load Speed/Voltage/Temp:

4500mhz / 1.33 / Max 54degc <-- should be noted my H80 is currently on "low" - before doing anymore I will be turning it up!

Filled out my Rig details - but quickly its a i7 2600k with a H80 Cooler on a ASRock z68 Extreme4 smile.gif

Not on purpose no - I don't know why it sits at 45 on idle - double checked the bios for anything and all seems ok, so im not sure!

Only for 20minutes atm


EDIT: Power settings, again >.< (Windows)

0% and 100% make it idle at 45

5% and 100% make it idle at 16 and load 45

Great! looks like you got it! Obviously these rigs are not behaving the same.

Hi guys, I'm new to overclocking and new to the forum, but this thread has been a huge help so far. I think I found settings that seem to be pretty stable, but I'd like your input to see if I'm doing anything obviously wrong or harmful to my cpu. I'm up to 4.6, but my core voltage in CPU-Z seems lower (around 1.18 under load) than what others are reporting: Here's my set-up:

CPU: i5 3570K ivy bridge
Mobo: Z77 Extreme6
Memory: 2x4GB DDR3-1600MHz, 9-9-9-24
CPU Cooler: Cooler Master Hyper 212 EVO
Case: Cooler Master HAF 912

BIOS settings:
I left mostly the default settings, but changed:
CPU ratio: All Cores x 46
CPU voltage: offset mode
Offset voltage: +.080v

It seems pretty stable at these settings and I get the following in CPU-z and Core temp
@idle:
Core Voltage: .944V
Core Speed: 1600 MHz
Core Temps: Max 30C

Underload (Prime95 Blend @ 30mins)
Core Voltage: 1.18 V
Core Speed: 4600 MHz
Core Temps: Max 72C

Any feedback would be greatly appreciated!

Thanks
