Cheers!
Kept it on 4 and -0.01. Played Skyrim for 2 hours and left it idling for a while.. no further issues and it applied updates without BSOD. My Gpu is also running at 950mhz nice and cool.
Thanks for the help. Fingers crossed the stability will continue. If there are no problems over the next 2 weeks I might try for 4.8!
You're welcome buddy, enjoy your new found Power.

Look forward to seeing your name in the 5GHz club in a couple of weeks
