33MH @ 100W in not so great imo. I have 29,7MH @ 76W.
Not at the wall. SW readings mean nothing. You gotta measure at the wall.
Yes i' have 7 X RX580 @34MHs | #90W in claymore but 155W/cards on the wall
It remains my opinion but I no longer flash my RX580 because claymore uses the straps and it works very well especially the claymore + phoeinixMiner combo
