New Computer boot issue

[rageguy34]

I just built a computer and have a problem when turning it on from a cold boot. It just sits there with a blank screen until I hold down the power button to turn it off and then back on. Once I do this it tells me that an overlock failed and to go into the bios and check my settings. It downclocks the ram to 1066 when this happens.

I go into the bios and pick the exact same settings as before and saves changes and reboot. Everything works fine and its passed stability with prime95 for 24 hours.

I have it overclocked to 4500 GHz with a 45x multiplier @ 1.26v, all other settings are on auto except for the memory which is set to use the XMP profile which clocks it at 1866 with 9-10-9-27 timings and 1.65v. Temps on the CPU under load are between 50C - 55C and idles 25C - 30C.

This is only on a cold boot, restarts from windows work just fine and it does not reset the RAM when I do that.

Here are the parts for my system

CPU INTEL|CORE I5 2500K
CPU CORSAIR| CWC H70
MB ASUS|P8P67 EVO
MEM 4Gx2|CORSAIR CMT8GX3M2A2000C9
PSU CORSAIR|CMPSU-850HX
SSD 120G|CORSAIR CSSD-F120
VGA XFX|HD-695A-CNFC HD6950 x2

So your overclock is failing and it's a boot issue?

If it works fine all the time at the normal non overclocked settings, then there isn't anything wrong.

You just have a chip that is intermittent or something. Turn down your overclock or increase voltage or something.

The overclock isn't failing, its 100% stable with the overclock settings. This only happens when the computer boots from a cold boot. Restarting does not do this. I suspect it has something to do with the MemOK! feature but I don't know how to turn this off.

This seems to be a fairly common problem with the Asus P67 motherboards, seen it mentioned in a lot of places. Sadly I have no idea if there's a proper solution.

Edit: Try resetting the BIOS if you haven't already, a some people say it solved their problem.

the point being made was that you should default back to stock settings, and see if the setup is stable without any overclock settings. When you power up, it reads the settings (overclocked or not) from the BIOS and applies them.. so you need to rule that out...

I think there is a MEMOK switch on the board you can press to override that.. Also check to ensure the TPU switch is off as well.....

Then clear/reset or tray another bios as suggested.. if you aren't running the latest and greatest...
