Hi Claymore,
Setting core or mem clock doesn't work for my Asus 7990. 380+390 both work though. The miner crashes in case i try to set the clocks....
Also can you please add setting the voltage? I want to move completely away from msi afterburner and i had some cases where after i rebooted the voltage was back to standard and the card overheated to 100 degree.
Which leads to another idea for your consideration: reduce intensity or stop mining on gpu when it exceeds a heat threshold. Recently one of my fans broke i only noticed after the whole rig had crashed....
Anyways, keep up the good work!
