I hear this is due to either 1. a PSU not putting out enough on the 12v rail, 2. voltage not enough on gpu itself.
As a note, I didn't update the GPU bios - It was the chaintech vnf3-250 bios that made the biggest difference. I also updated that jpg in my last post, reflecting a 4 count run @ 415/1130. This is pretty much my sweet spot with stock cooling.
I checked with RivaTuner and the standard 2D, low power 3D and performance 3D settings are all set to the same already
