Interesting, got two 280x on Win7x64 w/14.9 drivers. Getting about 147k on each card but nothing ever found on card #2, only HW errors?
Swap back over to known good sgminer cfg for DRK and bam, GPU 1 working solid. Latest gpu support was for cgminer 3.7.2 and this ver is 3.7.5. Anyone have any ideas?
Im getting the same thing with 290s(non x) all the accepteds show up on card 0, card 1,2 and 3 only get HW errors. Win 7 64 with 14.6 amd drivers.
