I'm having difficulties getting my 1060's up above 21Mh/s.  I'm hoping that the veterans here can help me understand why my hashrate is lower than others are getting, even with the 3Gb cards?

-  6 x MSI GeForce GTX 1060 Gaming X+ 6gb Cards
    -  Samsung Memory
    -  85% power / +125 Core / +850 Memory == ~64C

-  Windows 10 64-bit  latest version
-  8Gb RAM
-  16Gb Virtual Memory
-  Tried latest Nvidia drivers as well as driver 382.33 (read someone was using this version and got better results, I however did not increase my hashrate)

-  Using Claymore rev 9.5 (I know it isn't latest but had same results prior to 9.6 release) and only single mining ETH

I do not understand what I can do to increase my hashrate.  Any ideas?
