ASRock motherboard and i7-3770k overclocking help

post #1 of 3
Thread Starter 
Hey guys, I've got an ASRock Extreme4 and an i7-3770k and I was wondering why we have to decrease offset voltage. I mean overclocking usually involves increasing the voltage. And do i have to change the additional turbo voltage as well? I overclocked my CPU to 4.4 with 1.224V and it was stable with Prime95 for around 8 hours, but BF3 kept crashing so i reverting back to UEFI defaults and now its working perfectly. Am I doing something wrong? All I changed was the offset voltage to -0.05 and the multiplier to 44. This is my first time overclocking so any kind of help would be appreciated. Oh what speeds with what voltages are you guys getting?

I believe LLC is enabled by default which is technically over volting which means that you can still get a good OC with negative offset the problem with negative offset and LLC is that when the CPU isn't under full load you could be creating an unstable environment.

So I recommend turning the LLC to the second lowest setting and going to positive offset. Don't leave it on auto because ASRock is crazy with the auto settings.

I put mine on level 3 and it was stable until bf3, it was around 1.224V. After resetting settings bf3 runs fine but now my computer won't go into sleep mode. The screen turns off but the fans and everything are all still running, I'll have to force a shut down by holding down the power button and then restarting. Any ideas why?
