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.
I've obtained the kernel through reverse engineering, someone must take a look at the kernel and tell us if it brings any actual speed improvements.
