Here are my settings:
First I downloaded the latest
SPH-SGMinerhttps://bitcointalk.org/index.php?topic=475795.0Personally I like to move it the root level of the C drive
Then I create a BAT file and place it on my Desktop, then edit the example CONF file.
I have used Sapphire
Trixx to underclock memclocks of the 7970 and R9 290. The 5770 freaks if I attempt anything.
None of my cards are undervolted.
BAT filesetx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cd C:/GRS/
sgminer.exe -c GRS.conf
CONF fileThe cards are in this order: 7970, 290, 5770
Respectively they get: 5.2Mh, 9.1Mh, 3.15Mh
