Ok testing with vega 56. It really seems to be a power limit problem. With no real tweaking, just power limit on a stock 56 GPU, I get.
190w -19pl, 1300
235w 0pl, 1450
So, yes PL + 50 will get you good speed...but at an ridiculous power usage. This is stock 56 though, not soft modded.
Agreed, my watercooled Vega64 at stock clocks takes 500W to show 2200KH/s, it's crazy. Though it takes similar power in dual mining too.
Great work.
Tried it on my mixed Vega/580 rig and Vega's are doing good.
However; one of my modded rx580 (Anorak bios) cards, temp just goint through the roof, and I stopped the miner before it reached 80 deg c. The other MSI rx580 gaming X 8gb is doing fine. applied the -powlim etc. Aug23 driver. Any thoughts?
