Overclocking i5 2500k

Stinger53 · 24 Dec 2011 at 19:17

Hi i am new to overclocking and have no idea on how do do it.
I have a i5 2500K cpu and MSI Z68A-G45 G3
Currently i am using in OC genie mode which brings it upto 4.2GHz but would like to get it higher.

also are there any programes i should get to test it, i have prime alreadly but is there anything else?

thanks

http://forums.overclockers.co.uk/showthread.php?t=18340310 This didn't work for me but it worked for a lot of others. I managed to get it to 4.6 Ghz with fixed volts. Haven't tried going higher.

It's a similar board so might work for you.

Cheers for the link, is the any software i need to download? would 4.6 be the highest i could get it to? i've got a antec 920 cooler

Still can't overclock, i tried following the link, n it didnt work :/
could someone please tell me what i have to do
would like to get it to 4.5 or 4.6 if poss.
currently on 4.2 using oc genie

Best off doing any overclocking in the bios. Clocking an SB CPU is a cakewalk, it really is. You only have to touch two settings, multiplier and vcore. Start off with a multiplier of 40 (to give you 4Ghz) and a vcore of around 1.3v. Work the multiplier up from there, one step at a time whilst testing for stability in between. If you get a BSOD then either tweek the voltage up or back down on the multiplier. Note: use realtemp to keep an eye on temps (shouldn't go over 75c while stress testing) and CPUZ to keep an eye on vcore.

My CPU is pretty much an average clocker, and takes 1.28v to get stability at 4.3Ghz with temperatures hitting the mid sixties during prime stress testing (just to give you some idea). I could easily get it to 4.5Ghz but it was a little too toasty for my liking at this speed.

wat voltage would be a good? for 4.5/4.6

It varies from chip to chip. But i'd say an average chip would need around 1.35v. Anything under 1.4v is safe as long as temps are not going much higher than 70c. But try and keep it as low as you can whilst maintaining stability.

tried at putting it to 45 with auto vcore, and went passed first bit just before windows loads the screen goes black with a small white line in the top left of the screen

I wouldn't use auto vcore. Read my post further up and follow that.

Start at 4Ghz with a manual vcore of 1.3v and go from there.

thanks hopefully sorted, at 4.5ghz cpuz says vcore is 1.328. i set it at 1.35 so should i lower it on the bios?

is this ok?

if u cant see the pic
4.5ghz, 1.336vcore -cpuz
intelburn test on max
max temps across cores: 60, 73, 68, 68
idle temps across cores: 29, 36, 30, 36

anyone?

That looks OK - temps could be a touch better but nothing to worry overly about. IBT is a really good initial indicator of stability - once you're stable with that, try running Prime for 12 hours or so (or as long as you can). Very little will load your CPU like IBT does - expect around 10C lower temps when Priming versus IBT.

Yeh looks pretty good to me
