Is anyone successfully running 3+ V56 for extended periods of time? Using the usual settings I was easily able to get around 1800 H/s running on 3x V56 for a couple days with no issues. Got the fourth board setup and although it worked well enough at first the rig crashed after about 14 hours. Have it running again now with slightly lower memory clocks. If that doesn't work I'll probably try messing around with HBCC amount. Anyone else having stability issues with many GPUs?
