Hello everyone I want to start off saying I am happy to join Team Asus. Hopefully you guys can help me understand my problem and fix it. I am using a 4770k cooled by a Corsair h100 at idle it stays at about 28c. First thing off the bat I want to mention is i have not been over clocking long, I have watched many jj/linus videos and done some slight OC to other cpu's using just the Voltage and Multiplier. How ever my z87 Hero Mother Board has yet to be stable at anything other then stock settings, not even a OC to 4.0.
I attempted a OC to 4.5 @ 1.28 and pc would not boot it would get to the black windows logo and then restart. In fact it will only boot a OC of 4.2 and under, the odd thing is when I a stress tested it in prime 95 for a soild 20min everything was great so I stopped the stress test then went looking up things on the internet out of no where PC froze. Freezing only occurs when I have a OC set. I am sure it is a bad setting as everything is ok at stock settings, I can't imagine my cpu luck is so bad that it can't reach anything above stock.
I want to add that I am using a Corsair tx650 psu my video card hasn't came in as of yet so power draw shouldn't be a issue, I am also using 1 stick of Hyper X 4gb ram at 1600.

Welcome to the ROG Forum!
For me 1.28V for 4.5GHz seems pretty unrealistic… that CPU (at least the one I have played with) needed way more voltage… - but then the temps will be very high too…
Have you seen the OC guides here on the Forum? The red stickies on the top of the Maximus VI mobo section...

Are you OC'ing from BIOS manually or you're using some presets of the BIOS or AiSuite in OS?
Ok Zka I took into account what you said and I hit my cpu with a oc of 4.3ghz and fed it 1.32v and ran prime 95 for 10min heres how it looks. The problem doesn't seem to be stressing the cores, it seems when the cpu is just in a normal state it looks up. I hope this OC doesn't do what the others did and give me a random freeze while just on the internet, it has been running strong for the past 30min.
Try setting your uncore ratio to X40 to see if that's what's holding you back when overclocking. On a couple of chips I've tried the uncore couldn't keep up with the core so I had to have it at a much lower multiplier.
k heres a update Nate I was kept bumping up my vcore .10 til i was able to get prime 95 to run for more then 1 min without crashing atm it's at 1.36v in the bios. Ran prime 95 for 10min
