Question 3770k Overclock issue

[Gennaios]

preview:3770k
mobo gigabyte z77m-d3h
gtx 670 windforce
corsair TX 650

so I tried oc the cpu and it can't go past 4.2ghz
any more than that and system gets stuck at bios menu and I need to reset bios to get it working again
the mobo doesn't have an option for vcore voltage-its auto
in cpu z I saw it rising up to 1.2v
its a mobos problem its a psu problem!does somebody have an idea? thnx

It's a motherboard problem. The motherboard is lower end and has no core voltage settings. I don't know if it has a multiplier setting though, but I'm assuming there is, since you said that you could still overclock your CPU. 1.2 is a very normal CPU voltage though.

there is a multiplier, the thing is if I set anything more than 4.2 system crashes

That's not too weird, you'll cause instability when upping the multiplier without being able to manually change core voltages. I'm afraid there isn't much you can do but buying a different motherboard that does allow manual core voltage changes.

hello i oc my 3770k to 4.2ghz!anything more than that leads to crash and i have to reset bios!but my motherboard does not support core voltage options(z77m-d3h)
is there any way to oc it without changing the voltage?any settings that will auto increase the voltage?thnx
