I'm trying to find my max gpu clock on this old 670 but I'm getting this weird throttling at certain overclocks (70+ GPU) in Heaven 4.0.
My base clocks are 1006/1552, my k boost is 156 mhz.
Looking at this picture, you can see where it throttles, and what happens in Heaven is the screen goes black then goes back to the benchmark and continues as it was, but it's like the card "reset" itself, just not to it's actual base clocks.
The 0 values for GPU/FB/VID/BUS usage can be accounted for by a bios update that I did after installing all of these programs. Prior to that everything was reading as they should. I had the same problem with throttling prior to the bios update.
I can get stable at +53/475 (1201/3579), so I'm afraid I just got a not-so-good overclocker. Could mobo bios settings be a problem? Inputs appreciated.
