Here's another rig I have running Cryptonight-Heavy with GGS 1.3.7 alpha. This rig has 10x RX 570 8GB Nitro+ but somehow Windows 10 detects them as RX 580 after upgrading to Adrenaline 18.4.1



and my GGS settings:



Those churning ~820 h/s are Samsung DDRs and the rest at ~750 h/s are Hynix

I haven't toyed with the Memory Timings, kind of scared to fuck up my cards.

Anyone can help me improve my hashrate please? 

Will be happy to give a tip (0.005 BTC) if someone can help me get them to ~900-1000+ with stability.
