This is with no nothin' fiddled with in terms of Classified Tool, haven't used it at all yet, and the settings are displayed in Afterburner... only got to around 450W draw during the previous test I did with GPUz open, this was with everything in the background closed:
Can't go a single step higher on the GPU core or it will crash pretty early on in the benchmark, but these settings will run several times in a row with no crashes, haven't had any problems yet getting it to pass PR. I'm going to save more benchmarking for tomorrow & get some actual games in, going to see how this thing handles an OC/undervolt for gaming purposes.
One thing I will say, this card runs very very cool. Max load during the PR test was right at 49-50C on the core, and the other components weren't much or not at all warmer than that.
Screenshot of a previous run with GPUz open, on the "Normal" BIOS:
So it runs those clocks on both BIOSes. Just gets PWR limit on the normal one.
