80Mhz core and 200Mhz Memory overclock is a pretty big step. Was this all in one go or a gradual increase?

What your experiencing, I think is your driver restarting because your overclock isn't stable.
Back down the oc, start from default clocks, increase in small incraments (5-10 MHz) and check out this thread for info on AMD GPU overclocking if you haven't already http://www.overclock.net/amd-ati/633...d-ati-gpu.html

Post back with any further questions, and add your system specs here http://www.overclock.net/specs.php?do=addsystem it helps us help you.

Sorry, links are fixed. Be sure to test your overclocks before continuing. Fire up a game that will give your gpu a workout and look for problems.
Again, sorry about the links... Be sure to check the first one for a really good guide.

Only way to see is fire up your favourite game and see if there's any artifiacting/unusual stuff happening. If there isn't you're golden. Good luck!
