Thanks. That’s a pita, but I’ll give it a try, as I am only getting 45khs on my 7950 and 130khs on my 7990 with 3.7.5
As mentioned in the other neo/GPU, wipe the 14.xx drivers, install the 13.xx drivers and use the settings there to create the bin files in the cgminer folder. Then install the 14.xx drivers to mine with higher speeds than you can with the 13.xx drivers.
If you don’t have the bin files from the 13.xx drivers, all you get is h/w errors. (at least that’s how it worked for me)
