Thought Id throw in my two cents - I actually prefer not to use risers and dont plan on messing with any setting for the most part - plug and play mining.
Kit: Running 3x 1080ti with 1 still in the box (no risers and in corsair 540 on z270 xpower, 4th gpu is possible but would cover psu/h100i usb headers and front panel connectors) - will have to make a second box with 1x1080ti and 2x970. Running the 1080ti's on ~80% fan and 70% power, keeping everything under 80 degrees on air cooling no issues at all.
Running on zpool + Nemo switcher, just leaving it alone totally stock for now auto-switching have been seeing ~.015BTC per day minimum payouts for the last week.
What coin was it running the most of?
blake2s(Taj/Netko/Verge) is by far the most often/most profitable coin that the auto-switcher has been running on, and x17/c11(Chain/Flaxscript)/neoscrypt/hmq1725(Doubloon/Topaz)/lyra2v2(Vert) algos are the most often interspersed fillers in there.
When I see blake2s running at 18-20 GH/s I know it should be a pretty good day. I'm out of town but looking forward to adding that second box for a 33%+ boost in profit from this one location.
Note - The rent for the apartment that these boxes are in right now includes electricity so I have the fortune of running as many 1500w systems and A/C as I want without any dent in expenses. Each 3x1080ti system would probably cost 100-150USD per month in electricity at 12-15c/Kwh which would be a tough bullet to swallow.
I never really understood the methodology behind running single large rooms with 10+ systems in them, much rather keep 2-3 systems spread across multiple apartments or houses with RAT on Windows for reliability's sake. Rather RAT than tunnel because the minute I open a new center or want to sell a system I can easily clean it over the network and have a friend list and sell the Windows system as its own rig without flying there which is nice.
