Hello there this is my first post for chrismass I got a intell I5 4670k and I was hoping to overclock it to at least 4.4 GHz but it seems to only get up to 4.2 GHz with 1.20v. Once I was able to get it up to 4.4 GHz with 1.28v but it lasted like 20s in the uefi and locked up. I'm new at this and I'm not shrue if I'm doing it right so any help will be

Welcome to OCC!


Anyways if you haven't already you can check out the OCC Haswell Overclocking Guide. While it was written for a 4770k, it works for the i5 also.


looking at your system specs, it seem you have a H90 for which is great for cooling. The rest is good, even the power supply. I suggest you you check out the guide first and see if that clears up any problems. Worse case scenario 4.2ghz 1.2v is your limit, but I think you can get more out of it.


If your still stuck, your welcome to ask some more question and im sure the people at OCC can help you out :wave:
