starting to feel a bit frustrated with my 1080ti results.
So here's the setup:

ccminer alexis78_cuda9 on protopool

-p c=ARGO --cpu-priority=3 --max-temp=71 --intensity=18.05,18.35,18.05,18.35,18.05

gpu#0 Asus 1080ti turbo, 556MH/s
gpu#1 Evga 1080ti ftw3, 641MH/s
gpu#2 Asus 1080ti turbo, 552MH/s
gpu#3 Evga 1080ti ftw3,  631MH/s
gpu#4 Asus 1080ti turbo, 555MH/s

Afterburner:
cv 0%
pl 110%
tl 87c (actually set to 71c on ccminer)
cc +60
mc -320

If I up the intensity on the asus past 18.05, the rig shuts down. Same for evga, if I go past 18.35 it shuts down the rig. I tried similar settings using the ccminer_alexis_keccak and I get the same results. Starting to think this whole 1080ti 1GH/s mark is a unicorn, at the end of the day I end up with one coin per hour with all cards together running at mid 2900 MH/s with the pool fluctuating between 12 and 24 on the difficulty scale.

Any inputs?

Correction- used to get 1 ARGO an hour, for the past day more like .5 an hour :-/
