It's not instability because prior to installing the 310.24 beta driver the card had no problem sticking clocks with futuremark benchmarks. It only happens with future mark benchmarks.
I can run Cysis 2, UT3, BF3, Kombuster, without any down clocking issues. I haven't tried many other games or benchmarks but it only happens with Futuremark and it happens before the benchmark is even loaded. It down clocks when the benchmarks scans system before it begins and as soon as the benchmarks starts the clocks are already at 405mhz.
I think 310.24 programmed my card at the BIOS level to down clock during Futuremark. I have tried cleaning out the drivers and after cleanly uninstalling and installing drivers the down clocking issue is still there.
My card doesn't run hot at all.
The card is perfectly stable but this only happens with Futuremark and it happend right after I installed the 301.24 drivers.
Is there a way to get rid of the down clocking feature? I know it is a safety feature but I believe the 301.24 driver is forcing the down clocking. Before I had no problems running up to 1.1GHZ with futuremark benchmarks.
