Trouble overclocking 4670K

[yandaman]

I've been trying to overclock my 4670k on my MSI G45 Gaming motherboard for a few days now (first time trying though), and the highest stable overclock I've managed is 4.1 ghz at 1.25 volts, if I change the ratio any higher as soon as I start prime95 to stress test I just blue screen. My ram is 8 gigs of corsair vengeance at 1600 mhz if that makes any difference. 

 

Just thought I'd be able to push the overclocks alot more because from what I've read at 1.2 volts most people can get a  stable overclock at 4.4 ghz.  Any help would be appreciated  :)

Hard to say what your issue is with the very low amount of information you did provide.

But there always is the possibility of a bad chip that simply won't go any further.

 

Have you tried disabling C1-7 States and giving it a shot?

Whats your PLL?

Might just be unlucky chip

But try to put more voltages.

Tried disabling the Intel C states (only option I could find in the BIOS) and upped the voltage to 1.3 volts, but same story all again, tried from 4.5 ghz but keeps on crashing until its back at 4.1 ghz...  and how can I find the PLL? Going out now but I'll post that when I get back.

Check NCIX's video on how to overclock MSI Z87 boards.

As said above, it could just simply be a bad chip. Overclocks are not guaranteed, even on a K-series processor. I would recommend watching the NCIX video posted above first, and get back to us.

Good luck.

just go to 1.4vcore or try 1.360vcore and 2.00 PIV
