Aight guys i'm having a weird issue.
i have 3 pretty much identical systems

G4400+ asus h270plus/csm
6x Asus strix 470 4gb pushing 27mh/s ea

the issue is on 2 of the rigs after 15minutes or so GPU:0 on 2 systems drop from 27mh/s down to 8hm/s

restarting the miner gets them to work at 27 mh/s again but they soon drop back down to 8mh/s

I've replaced cables, and the issue persists is it possible its and issue with the riser or another issue all together?
