Im getting 277 h/s with my RX 470 8gb.
One of my 290s is doing 290 h/s but the other does 220 h/s. Will need to investigate that.
Thanks claymore.
WOW! 290 Sols/s on a 290? Is this a ref model? What clocks are you using? I can't get more than 260 out of mine.
R9 290 reference and near-reference cards (and by report R9 290x but I don't have any x) work much better for mining running a BIOS from TheStilt - even the ones that don't undervolt much if at all will still drop your temps a TON and let you overclock a lot more without hitting thermal limiting, while tightening the memory timings (like a strap mod for the RX series) to make them mine more efficiently even at the same clocks.
