Do you have external display connected to the other one that's underperforming and/or you are screening hashrates via teamviewer?
can a bad riser make that?
gpu0 640 sol gpu1 710 sol
all the same settings
Either a bad riser or a monitor connected to gpu0 that's slowing it down because it has to focus on displaying you a picture instead of hashing... Up to you to decide which applies to you!
