Verified Higher hashrate on 3 pools I use regularly.
Best increase was on my 270x Rig: 1450 to 1990 hashrate . So 270x(5) rig went from roughly 7Mhash to 10Mhash. Temps up just a few degrees, very negligible. Power up only 30 Watts on Kill-A-Watt to total 570 Watts on a 5 270x GPU Rig. Love the x11 mining for the summer so far.
Tried newer upload and I do indeed get temps and fan speed back in SgMiner.
CGMiner seems to work well also. Using Windows 8.1.
A couple of API errors every so often, but has been running nonstop overnight.
Seems legit so far, hope this helps someone.
