Hello,
I bought my first mining rig, with 5x Sapphire Radeon Rx580 4GB (Hynix memories).
When using ethminer, I cannot get anything over 22-23Mhs. I have already configured the bios using Polaris, and flashed them with AtiWinFlash, but nothing happens. I have first tried Ubuntu 16.04, and now switched to Windows 10. Same issue.
I have widely ready people saying that can get 30Mhs with this GPU.
I need some advice from you, please. My ethminer version is ethminer-0.9.41-genoil-1.1.9
My BAT file is:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
ethminer -G -F
