usually if driver reset is like the voltage is not enough, but some times it does the same when memory speed doesnt match with the gpu speed.

I'm leaning towards using GPU-Tool however I noticed that it mixed up core and shader clock readings. How reliable is the auto "find max" function?

Based on the adjustments options available with the tools available to me it doesn't seem necessary to flash my BIOS. Is it absolutely necessary to flash my BIOS to attain higher OCs?
1.012vid is a good vid, you sould be able to get 950mhz with 1.138, this on stock cooling,but you have to try step by step, first of all push to the max your gpu with stock voltage,(vantage ppu on loops, 3dm011 loops, heaven 2.1/2.5 loops OCCT GPU/MEM tool .. & so on) when u found that,start rising up the gpu speed until you get the max speed with max voltage,with an eye on temps, but be sure to match gpu speed with a correct memory speed.
