Thanks for the awesome forum and great advice. Spend more time on here than work. haha
I have two mining rigs:
3 x MSI Radeon RX570 Gaming X 4GB cards (MSI Carbon Gaming MoBo, i3 processor, 8GB DDR4 RAM, Windows 10, EVGA 850W gold PSU, virtual RAM set to 16384MB) - getting a 4th when the stock land here in South Africa.
This guy, I mananged to get +/-26MH/s from 2 cards and 23MH/s from the third, mining Ethereum with Claymore. Same bios mods (1750 straps to all above) and OC settings (1280 core and 2100 Memory using Wattman) on all 3. I am happy with 26MH/s, would just like to get all 3 cards hashing at this rate. Any idea why this might be happening?
Second rig is the one that breaks my head. I have 1 x Sapphire Radeon RX570 Nitro+ OC 8GB and 6 x Sapphire RX560 OC 4GB gpus (Biostar BTC Pro MoBo, Celeron processor, 16GB DDR4 RAM, Windows 10, 850 EVGA Gold psuvirtual RAM set to 16384MB).
I get a shocking 18MH/s on the 570 (bios mod 1750 to all above 1150 core and 2100 memory clocks) and a touch over 10MH/s (1050 core and 1800 memory) on the 560s. This morning I decided to change my layout and make the 570 my primary card and move the slots around. After this I managed 28MH/s on the 570 and 12MH/s on the RX560s.
Two GPUs failed after 3hours and after a reboot and firing up Claymore I am back at the mediocre hashrates and cannot get it up to safe my life.
I have the AMD Blockchain drivers installed(11 August Version) and mine using Claymore on both rigs.
Would greatly appreciate any input from someone who has had similar issues.
Thanks a million.
