It works fine for me without it - 17.7.1 driver and the same setup of cards.
Can you or anyone help me troubleshoot my SGminer error, "clDevicesNum returned error, no GPUs usable"?
OS: Windows 10
Drivers: 17.6.1 Crimson (Patched)
GPUs: (5) 480s / (1) 580
Bat File: setx GPU_MAX_ALLOC_PERCENT 70
sgminer.exe --gpu-platform 0 -k skunkhash -o stratum+tcp://sigt.suprnova.cc:7106 -u Username.Worker -p x -I 9
Pause
I've tried it with "--gpu-platform 0" platform "...1" too, either at the end the beginning etc.
