Help with my 2500K Overclock

post #1 of 2
Thread Starter 
Hello all. Got my Sandy Bridge 2500k yesterday and have done some overclocks. My mobo is a Asus P8P67 Pro with 2x4gb corsair vengeance 8gb.

So far I have managed 4800MHz stable up to 5 runs of IBT at 1.4v in bios following this guide. Here is an image, does it look ok?:




I can get into windows at 5ghz but it's not very stable. I went up as far as 1.45v in the bios. But it only lasted about 10-15 seconds in IBT before it crashed.

I know some of you will say use a test linx or prime 95. But IBT is quick, and I find a nice place to start to find out if a oc is stable or not. Once it does 5 runs of IBT then can move on to other tests.

I have never seen my temps above 70c. I am using a TRUE with push/pull to cool and it seems to be in very low 30's when idle in a room temperature of 22-23c.

I want to run 5ghz at 24/7, but would settle for 4.8ghz. Most of the people say 1.4v in bios is the most you should have for 24/7. Seems unlikely I will get 5ghz at that voltage.

Any help would be appreciated. Thanks guys.

Rather than increasing Vcore, i would try looking to see if the memory is not overclocked too far. Also adjust the CPU term setting to 0.2v behind the Vcore (If you have this setting). Maybe a higher multi and lower BCLK might help too. A too high of a BCLK can make overclockers hit "the wall". Also adjust North bridge Voltage. It's called MCH for me.

Hope this is a bit useful to you and good luck.
