Thank you for helping me optimize my 5600 XTs

Could you help me with my GTX 1070s? Right now I get about 26 MH/s with a power draw of 110W
I have the following settings :
Core MHz = 0
Mem MHz = 1000
Power Limit 110
everything else is default.
I know on Windows I used to get 30MH/s+
Any help would be appreciated, thank you

PS. I am using phoenixminer-v5.1c
On all GTX 1070/1080 cards you will need to keep increasing core a little with each epoch change or it will keep dropping hashrate, it will no longer be as high as what it used to be back in the days. Its caused by a driver bug that nvidia will not fix.
