Been following this thread a while, thanks all.
I have a small fleet of these and last night I was modding bios again and was able to reach what I think is a good enough point to share with others. Some of my gpus wouldn’t do 800mhz @ 900mv and others wouldn’t do 1525mhz… so 785 @ 900mv and 1500 it is.
I recommend teamredminer over phoenixminer, it reports an accurate hashrate which is nice and runs with less power, so cooler… Which is great for these cards since their cooling solution is so terrible. Who puts a plastic heat spreader on a professional GPU?
Core - 785mhz @ 900mv, Mem - 1500mhz
