I’m running ethos distro with the Claymore miner on a Asus “P8H61-M Evo” board with three RX480 GPUs. All GPUs are connected with riser boards.
While I’m getting hash rate of 275 H/s on the first GPU, the other two GPUs are on 63 H/s. I’ve upgraded BIOS of the motherboard to the latest version, but I’m kinda stuck now. What could be the reason for the low hash rate?
