Hello.
I have 6pcs Sapphire RX580 Nitro+ 4gb on fresh install windows 10, and the mobo that I use is biostar TB250-BTC. I haven't done any OC and mod yet. The hashrate that I got are 17.xx, 17.xx, 17.xx, 25.xx, 17.xx and 17.xx. Why got 5 hashrates abnormal? 25.xx is consider normal hashrate right?
Anyone could lead me to fix this issue?
Thanks.
It's probably a driver issue, if you have installed the Amd-Adrenalin drivers, you have to switch them from "graphic" to "compute" mode in your driver settings.
