Hello.
First post and I'm afraid I'm asking for help...
I have an i5 2500K running on a GA-Z68A-DH3-B3. It has the latest UEFI bios.
I have overclocked to 4.4Ghz at stock voltages and temperatures are well within limits. I've used Prime 95 and Intel Burn Test to check stability and it all seems fine, but if the PC goes to sleep for any long period of time, it will not wake up properly.
It will power cycle a few times and eventually show me a screen saying boot has failed due to an unstable overclock. However, if I ignore this message the PC will boot and run just fine.
I've read lots of posts suggesting adjusting the PLL voltage, but the UEFI bios doesn't seem to have this option. Would anybody be good enough to help?
