BTW, did you have to boost the voltage to run at 800/2000 stable? I'm currently running at default voltage, and most of time I would get a "d3d11 AppWindow::do swap(): device removed" error right about scene 14 of 26. This only happens in Heaven benchmark, and if I lower the memory clocks a bit, say to 1950, I would not get that error.
Then it must have been the second monitor somehow, or maybe it was because I had monitoring software like CoreTemp and Precision running as well alongside the benchmark before, and I didn't have any of that when I ran it on a single monitor.
I didn't have to boost my voltage to get it to go at 800/2000. But I have the GTX 480 SCs, so perhaps they are of better overclocking potential than the vanillas.
