Like the topic summary states, no matter which driver revision I use, if my system goes into standby after being idle for awhile and then I come back later and resume, the 2D clocks stick permanently. So if I turn on a game, the card's clocks won't move past 275 mhz core no matter what I do short of restarting the system. I've tried 77.77, 78.03. 81.84, 81.85, 81.87 to no avail, they all have the same problem. Anyone have some suggestions to this problem? It's very annoying having to restart my system everytime it goes into standby.
