cgminer.exe --scrypt --shaders 1792 -o pooladdress-O login info
I just recently added the shaders part and it didn't help at all
cgminer 3.7.2
cat 13.11, I might be on a beta version
crossfire is enabled, and I the check box to turn it off doesn't seem to be where it used to, I assume that can cause issues, it used to with BTC mining
Remove shaders and change it to --thread-concurrency 24001
or somewhere around there. Then change -I 12 to start, then ramp up to 18 or 19. 20 seems to get more hashes, but also more rejects.
