Wanting to push my CPU harder

post #1 of 7
Thread Starter 
Hi guys,

So yesterday I decided to OC my cpu because its an 2500k and its stupid not to. Now I got it to 4.3ghz stable with ease but anything past that I cant get past the boot cycle. Just wondering if there is anyway I can push it further? Tips would be amazing

Thanks x

What is your vcore at? Temps? What kind of CPU cooling are we talking about here?

Sorry forgot about that.

Well I have the vcore at 1.360v, temps are around 28-30 idle and 65-70 on full load and im using air cooling with a corsair a50 heatsink.

These are my settings @ 4.8Ghz. It's an ASRock motherboard, but most options should be the same.

OC Tweaker Settings



You might need to play with the Load Line Calibration Level and possibly need to turn off Overvoltage. They work differently for each person.

Advanced CPU Configuration Settings

I have success turning off C3 and C6, but you might need to leave them on.

DRAM Settings

Make sure you manually enter your RAM timings. For some reason the AUTO timings are completely wrong.

As I mentioned earlier, there are a few settings that you might have to play with. Overall, you should be able use all of the same settings for a stable overclock @ 4.8Ghz.

You do have internal PLL overvoltage enabled?
1.36V should be enough for 4.5GHz at the very least, I run the same Vcore at 4.75GHz

Vcore is bit high for 4.3 and the boot loop problem usually appears after a bad OC on P67/Z68 Gigabyte mobos.

By the way have you checked out the Gigabyte P67/Z68 OC How to guide by Sin0822 here:
The ULTIMATE Sandy Bridge OC Guide + P67A-UD7 Performance Review

This guide is pretty detailed and helped me getting my OC stable on my UD7.

I'd say the above suggestions are good ones.

My only concern is that you probably don't want that chip getting too much hotter and an A50 isn't the greatest for keeping it cool enough.
