Nheqminer - Low Sol/s for 1080TI?

[Lumikor]

running two 1080TI at stock speeds (no SLI bridge) but sol/s seems to be really low and it on the average of 900 Sol/s, WhatToMine says I should get 1270. Using Linux Mint 18.2 with Kernel 4.12.6 and Nvidia Drivers 384.66. I compiled for arch=compute_61,code=sm_61 with CUDA 8 installed. and running ./nheqminer -l equihash.usa.nicehash.com:3357 -u XXX.XXX -cd 0 1

Does anyone have any tips? I feel like I'm not getting as much as I can. I had similar issue with SIA, used different fork of ccminer. But it doesn't seem to work the same this time (used both original and Aayanl fork)

Thanks.
