Help for OC 2500k

post #1 of 10
Thread Starter 
Hey folks,

I got a ASUS P8P67 Rev 3.0 and a Intel i5-2500K.
Cooler is a Coolermaster Hyper 212.

Can someone give me a very detailed tutorial on how to overclock it properly without risking too much? I wanted to get ~4Ghz for 24/7. Is this ok?


PS: What happens to Turbo Mode if I OC? Do I have to turn it off or something? And how do I do it.

Seems to be for a Asus P8P67 Deluxe though. Or is it the same for my board?

And it's kinda bad written.. Don't really know what to change or why to change it to that value... They also go for 4.5Ghz, I just want 4. Sry I'm a big noob and dont want to take any big risks xD

Found these guides to be very useful:

Thanks they are better.

It says: For K series parts, the stock voltage supplied will allow for consistent overclocking generally up to a multiplier of 43x. There is potential for the multi to be raised to 44x depending on the load induced. This default voltage range be approx 1.240 to 1.260 under load.

So I just leave everything on standard and then kick up my Multi to 40x and get 4Ghz without highering the voltages? That would be awesome

edit: how to i enable the turbo mode so that my overclock applies? Or are the 2500k in turbo mode at all the time?

OC with sandy is so easy a caveman can do it. (zing!)

for 4ghz, you literally will only have to change your multi to 40 and tada, done. Even with auto voltage at 4ghz w/ sandy you'll stay nice and cold.

Yeah indeed... Got it now and temps look fine to me.. Did some priming and they stayed under 60° at all times. Whats bothering me though is that the 3rd core is like 8° warmer than all the others all the time xD Basically they all differ even if they are all on 100% load... Kinda strange but nvm. System runs great so far, but BlackOps still sucks ass lol. 89FPS on Havanna Street -.- With 16Ghz OMG! Learn to code treyarch

All you should have to do is set your multiplier to 40. You can either do it in the bios or use Asus AI Suite II. AI Suite II is probably the easiest way for you to do it. Open the program and click "Tool", and then select Turbo V. In the bottom section, you should be able to change the multiplier from 38 to 40. You may have to select the option for AI Suite II to make a change to your bios to do this. It will automatically do it for you. Reboot, then the multiplier should unlock.

I am confident that the facotry voltage is ok at 4 GHz and that you will not have to change anything else.

EDIT: Well, I was too slow. lol

EDIT #2: I think you can hit 4.5Ghz on stock voltage too.
