Looking to try any new straps for Sapphire Nitro+ RX 580 (11265-01-20G) with HYNIX memory.
Using PE 1.6.1 Good Hynix Mining strap at 2000 and 2250 only gets 765 (stable, no mem errors ever) at 1250/2250 for XMR.
Well, no thanks to anyone here, but I've managed to mod the ROM and get 833 (stable) at 1210/2180 for XMR with Claymore 10.2.
