OK..... giving up on overclocking for the moment.
At 1.44v after about 1.40hrs I ran in to the issue where the gpu/monitor loses connection and cant be woken up. I had only gone this high because of this issue with the monitor.
Of course during those 1.40hrs it had successfully woken up 4-5 times.
Maybe my chip cant do 3.9Ghz then because if this is overclock related, I need 1.45v minimum.
@AMDMatt - Do you know of a voltage I may need to tweak to alleviate this behaviour?
The internet seems to suggest playing with CPU PLL voltage but that's for Intel boards I believe.
It's annoying as it's impossible to overclock like this. I don't know if the monitor not waking from sleep is due to overclock or something else. As said above even at 1.44v the monitor was fine 4 times in about 1.40hrs then on the 5th time failed to wake.
My only option is to go down to 3.8Ghz and see if it exhibits the same behaviour.
Also need to check if it does this behaviour at stock too.
The symptom when it happens is the gpustoplight goes off, which usually means the GPU drivers have disengaged from the hardware. You usually see it when the PC is booting and the gpu drivers haven't taken control of the card.
