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.
