<p>What the best overclock setting for 5930K I have hard time keeping it stable at 4.5ghz. I'm currently stuck at 4.4ghz</p>
 
The 5930K that I had previous which KIA when my PSU blow out on me back this winter.  That previous overclock to 4.5ghz with no issues.

What the best overclock setting for 5930K I have hard time keeping it stable at 4.5ghz. I'm currently stuck at 4.4ghz

Some chips just aren't as good as others. I'm in the same boat - I can almost get my 5820K stable at 4.5GHz, but it eventually BSODs my PC. So back down to a perfectly stable 4.4GHz I went.

My 5820K's stable till 4.6, but my chip is a very leaky chip, 190w at just 4GHz, 265w at 4.4GHz, and Prime95 is too hot to run on 4.6 but even non-avx2 loads were pushing it well over 250w.
 
• Core is still king, so keep XMP off (leave memory at auto 2133 C15 etc).
• Disable C-States (i cant seem to run any OC above about 3.8 with them on).
• Put the voltage to either as high as you're willing to risk (id say dont go too far above 1.3v, you'll be cooking the poor chip above that).
• Then dial up the multi till you hit the limit.
• Once you've hit the stability wall or temp wall, drop back to the highest stable multi, and lower the voltage till it becomes unstable, then raise it a little bit (if you were stable at 1.275v but not at 1.270v, 1.280v will give it a little freedom for varying conditions in the room etc).
• Once you've got your max Core clock set, try bumping your cache up, you won't get any higher than 3.6GHz unless you're lucky, since EVGA boards don't have the OC Socket.
• Once your core/cache are set, try setting XMP, if it boots up alright etc, run memtest for a while (sometimes you will still have slight issues with higher speed ram that aren't necessarily caused by the ram itself)
• If you can't get XMP running, try lower the memory by a multi or two, and test again, lower the timings once you get it booting.
• If it bluescreens after leaving the pc off for a night (cold boot), then your IMC is on its limits, try dropping your memory down a multi and get the timings as low as possible.

I'm pretty much in the same boat as many others.  Rock solid at 4.4 but when pushed to 4.5, I can run it but will eventually become unstable when folding after a couple of hours.  Granted the voltage is under 1.3v and the temps aren't an issue.
