What is your GTX1080Ti power consumption and core voltage at that core clock (1999 Mhz) ?
+250 to core clock for GTX1080Ti it really great - more than 15% to base clock increase
I haven't had a chance to hook up a current probe to this rig (because it isn't really a mining rig, but my work / gaming rig). Running CryptoNight as well on the 6700k CPU, which adds another $0.50 / day to whatever the GPU is mining.
It did fall over finally last night when it switched to mining Skunk using ccminer_tpruot. So I dropped core down to +200 for the time being until I get a chance to play it is some more. It's doing 55 MH/s on Skunk though, but temps went up a little to 40C.
