stressed stressed and stressed! i7 2600k OC

post #1 of 17
Thread Starter 
So I have been OCing this chip for a few days now, and i was having great results, locked in a x46,x47, and x48 OC they did well in 1 hour OCCT stress tests. When i attempted to try the x49 is when things started getting weird. The x49 was booting into windows just fine, i did a few restarts just for good measure, then when i started OCCT stress test i got the BSOD , didnt think much of it and proceeded to up the voltage from 1.385.
This is when things got even more weird....since then even the old setting for x47 and x48 were not posting and i would get stuck in the ongoing reboot cycle culminating in BIOS checksum errors , leading to me having to reinstall the bios back to the latest version of f7a. Anytime i try an OC passed x46 i run into these problems and have to reinstall my bios to f7a from the defaulted f3.

I just dont understand what is going on, the x47 and x48 OCs i had were working just fine and now they wont even post when i have the BIOS updated and set to their settings.

A few questions,
why is the system getting stuck in this boot cycle on BIOS changes that have previously worked for me?

Is my chip damaged?
Is my mobo damaged?

I would think the answer to the chip and mobo question is no simply becuase the x46 multi have is OCCT stable and tested. Its anything above this is where i run into problems. When i was testing the x47 multiplier i was running vcore at 1.365, that only lasted 3 minutes in OCCT , so i upped it to 1.370 that only lasted 1 minute, so i tried 1.375, this is where the problem i have described starts to happen, when trying to save settings i get stuck in the rebooting cycle untill i get a BIOS checksum error!

Please anyone , i am using a gigabyte-p67-UD7.

Try using the F6x BIOS. When I had my UD4 I had the same problem with all the F7a,b,c,d BIOS's.

But if my OCs get high enough i will need to be able to use Internal CPU PLL overvoltage and that is only present in f7a?

Nope, F6x supports it. I got mine to 5Ghz easy with it, you can too

same thing happens to me. i cant see your sig, but on my gigabyte board, if that happens resetting to default and then reflashing the bios usually fixes the problem.

im using bios f7e which has yielded me a benchmark stable overclock of 5.5ghz on a 2600k.

the thing that bothers me is i was on my way to a x49 OC and now nothing over x46 will even post...i will try your bios version and see what happens.
