I have a user who reports 524 MHASH in a 2 card rig. (2x 1080ti)
262.5 MHASH per card
He use an intensity of 60
I think that was me. I can't get 3 cards to work without crashing my G3258/60 rigs. Max 2 threads per rig or 1 thread and mine other coins with other 1080Tis. Running 5 cards for now and haven't found a block in 4 hrs.
