Thanks for the miner update. it's been mining without issue for a few hours now.

 ( using my Cryptonight v1 clock settings)

5x rx580 8g 23 sols/s per card

6x rx580 8g 23 sols/s per card

13x rx570/580 4/8g 21.5/23 sols/s per card

I'm sure hashrate can be a bit higher if/when i get around to tweaking clocks.
