Thanks for the miner. I was seeing some crashing with GGS 1.2.5. It worked well at first then I had a crash after about 12 hours, then it crashed pretty constantly after a few minutes so I've installed GGS 1.2.7 and installed 18.1.1.
I reverted to stock settings for now, minus the memory timings (1500 copied up). Two MSI RX570 Gaming X 4GB Hynix AJR currently getting ~600KH/s on Neoscrypt. Looking to prove that the crashing is resolved and then work to get more out of these cards. I'd love to get near 1000 KH/s!
