USE A CONFIGURATION FILE--

Take the following and paste it into a configuration file, i.e. "test.conf".  Run sgminer with "sgminer -c test.conf".  I do not think SGminer-GM supports the SSL URL.  Be sure to set the environment variables prior to launching SGminer-GM.  So, in a Windows batch file, the variables will precede the SGminer-GM launch line above.

Configuration File:

Raw Intensity can be adjusted to 1008-1016, or cut in half with "threads" =2.  If you have a smaller GPU, you may need to use 1/2 the Raw Intensity with "threads" =1.  If you still have trouble, start with RI = 896, or 448.  Worksize could be 4, or 8, but adjust RI accordingly.

SGminer-GM runs for weeks on my AMD cards.       --scryptr
