Cant get above 4.0 Overclock 3570k GA-Z77X-UP4 TH



Well the stock says something like 1.185 I believe and I started at 1.105 at went up to 1.120 +005 increments and then it crashed so I went back down. I should be going past this ?1.130 or something?
 


I have the Hyper 212 or something: COOLER MASTER Hyper 212 EVO I haven't changed any fan settings in bios

I don't know much about under or over volting
 


Thanks for the help I will look at the guide.... I was able to get it to 4.2 with 1.25v running a few hours with prime top temp was 80.
