Thoughts on my current overclock? core i5-3570k with Asus P8Z77-V Pro

If it turns out to be completely stable I see no issues with your temps and vcore. You might have to bump vcore a little bit more but you have headroom still it looks like.

Good luck on your overclocking adventure 🙂

Thanks for the suggestions, Kenmitch. I'll have to try that when I get home.

As for the current state of things, I had a successful run of 20 back to back LinX runs with no errors. I ran it overnight, but to my knowledge, the thermals topped out around 63C on core three (it always likes to run hot) with a 4.4GHz OC, and voltage topping out at 1.184V but generally staying closer to 1.176V.

If it stays stable at or near this voltage, I'm guessing that's going to be pretty close to ideal. Anyone able to get the voltage and temps lower with a 4.4GHz, or is this pretty damn good?

You may be satisfied with posts from our illustrious colleagues here -- and they've provided enough information. Just thought I'd throw in some little extra.

I'm running a Sandy Bridge K-chip on a Z68 mobo. From what I've read and seen here, there's not a lot of difference between BIOS options and a Z77 chipset. But -- right -- you'd want to keep VCORE on "auto" and using offset-mode, adjust the offset. There may be also another voltage setting under "power management" unless ASUS changed the organization of their BIOS' a bit -- "Extra voltage applied in Turbo mode." That, too, can be tweaked.

The onboard, switched or AI over-clocking features on the ASUS boards definitely give you excess voltage at that nominal 4.4 Ghz result. I found that it is a good idea to use that feature initially within the BIOS -- just to see what is easily possible. You can also look at voltage readings in BIOS at stock and in Windows to see how voltage ramps up by itself with default settings between 3.4 (or whatever) and default turbo (3.8? Depends on the processor). Then you may have a handle on how to start adjusting the Offset to get minimum stable voltages under load conditions. It's more work , but more methodical.

I can only say I was pleased with the result on my Z68 mobo and 2600K.

Also, someone here may already of said so. Get the latest revisions of all stress-test and monitoring software -- hopefully with release dates following the release of your processor and mobo.

thanks for the suggestion. I'm currently trying to conquer an odd little kernal-power critical event that's causing system reboots now and again. I'm guessing the 1.168V wasn't enough for 4.4GHz, or possibly my RAM wanted more juice. I've been slowly upping the offset and it is currently up to +.070 resulting in a fluctuation between 1.176V to 1.192V under heavy load., with my Samsung RAM at 2T, 1600 Mhz, 9-9-9-24 timings and 1.4V. Let's see if it asplodes from hardcore BOINC.

A side note, I was getting the kernal-power events before I put in my two Geforce 670 GTX cards... and a few afterwards... bleargh.

Zombie thread here, I guess... so... yeah. Windows 8, a new monitor, and Borderlands 2 at rather ridiculously high settings = Borderlands 2 crashing. Updated the mobo BIOS, my settings were wiped, and running things at stock solved the issue with borderlands 2.

Despite all the previous testing / hours and days of "burn in" it would seem that games made my OC unstable 🙁

I didn't think to write the info down, so I'm having to start all over again. Bleargh.

while you mess with multiplier and vcore, leave your ram on 1333 lose timings till you get stable first at stock speed, default bios settings.
If ok then try setting to 44x and last offset it was good at, you probably need slight bump since it crashed . something around 1.20 - 1.25v should work ,thats where most of them run but YMMV

I'm not to worried about getting a manual setting working again, but holy monkey balls... offset is being such a pain in the ass. The base offset value seems to (for no obvious reason) be around .2 volts different at max CPU load from one boot up to the next.
How the hell do I reign that in / regulate that?
