There is something wrong Ranger, this is my i3
http://prntscr.com/hkxkph On the .bat file, put option -t 4 at the end if you have 8 Mb cache or -t 3 with 6 Mb cache like my i3.
Try if it can make some difference.
Yea that is what I have, -t 4 , and still can't get over 170h/s with nothing else open on the pc except the miner.
