Hi everyone,
I am a beginner at overclocking. I want to get into the subject directly. I have a mobo maximus v gene z77, corsair 4GBx2 1600mhz corsair low profile memory, 3770K, gigabyte gtx770oc windforce 3x and thermaltake 750watt 80+ psu. I have never been succesful in ocing at 4.5ghz wilth cooler master evo 212. I tried some guides found in internet. The best time I achieved was 2 hours at 4.4ghz than boom BSOD. Is there anyone who can help me to find a stable oc spot in my experience? Thank you all in advance.

I would suggest that your cooler is not able to manage the heat. Either try another cooler or lower your expectations. The CPU is quite warm my friend.

What kind of voltages are you using?
To help us help you - please provide as much information about your system and the problem as possible.

Hi,

Thank you for your interest. I used between 1.22 - 1.235v. Temperatures looked ok to me. 72-73 max is not much I gues. Am I wrong?

Was that each core? Or the entire package.

I have used that cooler with system builders at a couple of stores and it really struggles to hold the load. However the voltages you are using will not generate the wattage to cause the cooler to fail. That means there is something else.

Could you please tell me what settings in bios you change to OC to 4.4GHz?

I will do it in 2-3 hours when I get back to home. Will check bios than tell you exact settings. Thank you by the way.

Windows could not load at the first run. At the second, it loaded but when I started prime95 bsod immediately.

OK we now know that your system needs more voltage. 1.400 vcore please.

Well...Are you sure of that? Isn't that too much?
