Overclocking my i5 2500k

[Kyze]

Hey guys, I decided to give my 2500k another go and im in need of some help!

ive watched toms 1155 oc vid (again) and im having a go on it.

im on a 2500k on an z68xp-ud4 but with the award bios (non uefi).

Ive set the vcore to 1.25V and upped the multi&turbo to 42.
LLC is set to level 5 (0-10).
Ive left c3/c6 enabled, however the rest is disabled as recommended.

Linpack is still running, temps are 61° max.
cpuz and occt shows a vcore of ~1.3V.

How is this higher up than i set ?
Is the LLC kicking in right here ?
Should i go further (VCore) ?

EDIT1: Half an hour successfully run, pic of vcore is kinda weird:

EDIT2: 4.3GHz went another 30 min, 4.4 crashed after ~5min.

This is more advice than it is answers as I can't remember exactly all my setting but all I know is it took me 3 months and I was running 4.8GHz @ 1.48v for 9-10 months before I sold the CPU. Max temps was about 82-85c and about 65c while gaming on a h100i with fans turned as low as possible.

To get to this point took me 3 months not only because it was my first good CPU but because it was my first time overclocking. I had absolutely no clue about overclocking at this point, but of the box I managed 4.2GHz "stable" prime95 and such, I say stable in quotation marks as it soon came apparent to me that these "stability tests" was not the best way of checking as prime95 and occt saying it was stable then BOOM a simple task like opening my 15th tab in my browser a few days after the "stability tests" takes that stability away, don't get me wrong, they are a very very very important part to maintaining stability but after the tests coming back as stable, well that's when the actual testing begins like real word tests such as rendering, gaming and everything else so I'd give it a whole week of real world testing before I push the CPU further and this is how I achieved an overclock of 4.8GHz 99.99% stable for 60-70 hours a week usage for 9-10 months and not 1 problem. I even managed to have a setting to benchmark at 5.1GHz

The key is patience and real world testing before you push it further and lots of google, as much as I love this forum and I can honestly say it is the only PC enthusiast forum I use regularly but I still found my self all over the web as there is as much information you need on the 2500k. It's nice to ask questions but sometimes the answer is already there instantly, this is how I managed my stable 4.8GHz and 5.1GHz benchmarks

LLC will increase the voltage in windows, and it does so by a lot on the gigabyte boards......i have my 2500k in a gigabyte Z68X ud3 board myself, and at LLC set to 5 it adds about .1v in cpuz/occt. Also v droop on my board anyway is horrable......can go from 1.36V no load down to 1.30v - 1.29v under load, and i have yet to find a way to correct that

Thinking about it I don't think I had any voltage drop ever, I wish my memory was better, I'm so bad at remembering things long term.

from what i understand the voltage droop is just extra bad on the gigabyte z68 boards

If it's anything like the AMD boards they made back at the time then they're awful for V-Droop. I couldn't control it properly with my FX-8350.

ya its fairly bad, and the higher i go in voltage, the worse it gets.....i cant get over 1.42v under load in cpuz no matter what i set the bios to. If i set it to 1.5v under no load, it drops to 1.42 at best under load...

Alright, i think im just gonna leave it running at 4.3 for a while and get on overclocking when im going on a new board/cpu sometime.
