Do you have external display connected to the other one that's underperforming and/or you are screening hashrates via teamviewer?
no, just looking at result on the sm OS website. nothing is connected to the rig
I figured it out, there is something in bios needs to be changed i think, because two long ports give normal results, but if one card is in that small port that card have like 15% lower hashrate. Do not know why yet, but will figure it out.
