does hash faster with the "normal" AMD driver or the blockchain one?
With blockchain drivers hashrate faster. About 980h/s on RX480 8G samsung
At what wattage is that?
About 680W 5*RX580 "from the wall"
that's really great. I just optimized a bit my RX470s 4GB and it is around 850, can't squuze more. This pulls 620W for 6 GPUs. Compared to sgminer it is better hashrate at a lower wattage.
Would you share your core freq pls?
