OK, I just checked and it is not selected.

Thanks for the reply.

Something you are running is trying to change the clocks, you have going to have to go through a process of elimination to get to the solution or use a different toolset/BIOS combination.

I had a similar situation with Gigabyte cards and the catalyst driver set that I could only cure by using MSI Afterburner and getting it to force a constant voltage. In the end I swapped the BIOS for one with a set voltage and removed the problem that way.

Make sure you have disabled AMD Graphics OverDrive in the Performance Tab of the Catalyst Control Centre

My system while mining seems good (high 800's Kh/s) except that about every 30 seconds the screen flashes and I notice that my core clock and memory clock drops from 920/1500 to 300/150, I took screen shots of the spikes while mining and also when it does spike.

Could anyone please take a look and help me problem solve this?, I have not tried changing the voltage.
