i don`t see any ppd increase with pl 220, on both cards tasks 94xx and 117xx produce same 1+ mppd
set pl back to 180

so, have tested 1080ti @ pci-e v2.0 x1, ryzen platform mentioned above
task 9415, at 20% progress shows 856k ppd
nvidia settings console shows 11% pci-e link load.

well, 1070 will fold with full power, may be even 1080 will.
but 1080ti not, it requers at least pci-e v2.0 x4 (may be x2 if that kind exists).

That is important especially for those mining mainboards with pcie v3.0 x1 only. So with Linux using gtx1070 would be feasible if CPU is big enough, 4core/8thread would be good for upto 8 GPUs. So a mining rig with 8x gtx1070 can be converted to a folding rig just by replacing the CPU from often used dual core to intel i7 and using Linux.
