I think nvidia performance gains are just troll
12 1060 micron (no strap) @ 635mV (little bit more efficient then pl 70)
ethminer about 275
14.4 clay about 274-devfee
phoenix about 280-devfee, but it drops connections to the pool after about 26 hours and keeps mining, so totally unusuable
reported hashrates - ie. for phoenix it would be about 272 on pool and for ethminer about 269 on pool

clay "-strap 4 -sintensity 1" I need to do more research, but maybe claymore really can change timings on gddr5 nvidias - that would be very very unique and awesome functionality and I don't know of any other publicly available SW that can do that.
Currently I wonder if miner will come back up after restart and still able to mine


Update: so I resterted and got ~284MH/s(-devfee) - I guess maybe in time there will be better straps for nvidias (seems like it is actually applying straps for 1060 and such! WOW). And I also suppose it could get better if cards would not run on 635mV - maybe there is more gain if we let cards bit more juice with better straps?

With 700mV i'm getting 305mH/s per rig @ 900w - which for my power cost is about the same.

But yes, i believe p106 samsung will do 27.5MHs on full power no problem

Update 2: so from the description on first page it seems strap 2 or 3 should be the most intense, now i'm trying 3 and it does not even start minig, so probably I'm on square one and need to lower memory OC etc.
Strap 2 even crashes whole system - nice.

Very interesting and very nice work!
