help me get my 2600k way past 4.8 ghz

cammy5477 · 8 Oct 2011 at 21:17

just set up my new rig and i can get the 4.8ghz turbo overclock to run at just below 1.4v and the temps are fine, i want to see were i can get this to but its all new to me on sandy bridge coming from i7 950, ive tried a few things changing the multi to 50 etc etc but it wont post

could somebody tell me what i need to enable and disable to get this to really run? :eek:

You need more vcore, try 1.45 for 5ghz.

Check through my posts, I posted up some screens for my 4.8 settings (pll llc etc..) try those then it 'should' be a case of increasing MP and offset/vcore. (provided your on an asus board anyhow)

It seems sandy chips have some sort of voltage 'wall' that once they hit it they require a big jump in voltage to get stable. Example, 4.8 for me needs 1.312v, 4.9 needs 1.376v but 5.0 needs in excess of 1.46v...

At what speed you hit the aforementioned wall depends on your chip.

it runs 4.8 ghz with ease which makes me think theres a lot more headroom there
i will try it with a bit more voltage and report back

what is the safe voltage for the 2500k on OCing

You dont just jump to 1.45v. You do incremental increases. Just banging in the highest safe voltage isnt smart overclocking. He could be running 5ghz at 1.45v, when all he needed was 1.4v So he'd end up running a hotter system than he needs to be.

super stable at 4.8 ghz on the factory over clock setting but cant get it to budge from there
im used to asus and gigabyte mobos and the one i have now is the asrock extreme 4 gen3

I went up 0.01 until I got to 1.44v for 5Ghz. Prime is stable and it passes the intel burn in test.

He can make sure it works and then lower it, SIMPLES.

i think if i can get the offset voltages worked out it would sorted

To work offset out, put a manual overclock 1.4v for example. Boot into windows run prime or ibt to put it under load. Open up Coretemp and take note of the VID, open up cpuz and take note of the vcore. Then work out the difference between the two. Example. 1.40 vcore...... 1.30 vid. Would be +0.10 offset. Well thats how i work mine out anyway.
