Fx 8320 @ 4.2GHz
Asus M5A99FX Pro.
Corsair H60 liquid cooler
GSkill 1600MHz DDR3 (16gb)

Followed an overclocking guide found on the internet along with guidance from several threads in TH. Tested in Prime95 for an hour with temps stable at 55C while under heavy load. Normal operating temps range from 25-40C. Everything was running fine for several weeks. Two days ago while playing a game the computer shut down and reset to a screen that said "Overclocking failure. Press F1 to enter setup."

When I pressed F1 it sent me to Bios where it had reset to factory defaults.
I repeated the process to overclock the CPU. This time I have it set at 4.0GHz and everything seems to be fine again. What happened? Is 4.2 mire than my CPU can handle.

Also the temps at the time of the incident where fine. Around 40C while gaming on the CPU and the socket temp was about 50C.

I've only had that when I've tried to overclock the RAM or the CPU using the FSB, it doesn't look like you have adjusted the FSB at all though?

Different motherboards and processors will have different capabilities when it come to overclocking.. even if you followed other PCs guide or with exact specifications.

But going back to 4.0ghz of you Vishera, that speed is just its max turbo.

Run memtest see if you ram will pass.
If your system is running fine with 4.0ghz, I suspect your psu may not be sufficient for higher power requirement. I can't find your psu in the list. :) 
Re-seat RAM, clear CMOS and change CMOS battery.
