if you can stabilize oc setting -strap 2 gives good results without rejects using 1080 and 1080Ti, it is better than pill:

my oc settings: TDP 70%
1080Ti zotac core +90 memory 0
1080X3 evga ftw core -170 memory 500
msi gamer x 1080 core -70 memory 500 (using even tdp 73% since this gpu gives less hashrates than evga ftw)

since all stales gone might increase core even more and reach 193mh/sec maybe, for example 0 for msi gamer x and -50 for 1080, not sure why but after recent changes 1080Ti memory +500 gives zero hashrate boost
