I use ccminer-x64-2.2.3-cuda9 and NVIDIA driver version 23.21.13.8843 from 27/11/2017
Now there is new NVIDIA driver from 07/12/2017 but I can't decide do I want it or not, because finally I see what I should see.....
Sorry for my $0.02: you are using wrong miner and wrong driver. Therefore you are loosing approximately 18+% of hashing power and profit (according to my calculations).
You have to use
ccMiner 2.2 fork by Nanashi Meiyo-Meijin For MonaCoin Mining miner: just download it and rename to ccminer-x64.exe if necessary (f.e. minerwatcher.com service which I use requires it).
Driver also should be the latest: 388.59 gives the most hashrate in Lyra2re2 I've seen so far.
my old ccminer from 2015 gives me better hashrate (same as the one used in OCM without the 2% fee)
