Hey guys, I am knocking my head to the wall and been search around for a day!
I get this:
\sgminer.exe -n
[01:20:34] CL Platform vendor: Intel(R) Corporation
[01:20:34] CL Platform name: Intel(R) OpenCL
[01:20:34] CL Platform version: OpenCL 2.0
[01:20:34] Error -1: Getting Device IDs (num)
[01:20:34] clDevicesNum returned error, no GPUs usable
[01:20:34] 0 GPU devices max detected
This happening using both sgminer-5.5.5-gm-nicehash & sgminer-5.6.1-gm-nicehash. All other miners (Claymores, Excavator, etc) are working fine on this rig.
Driver: Latest AMD Blockchain driver
GPU: RX580 8GB
OS: Win 10
For some reason, the sgminer initializes only the integrated Intel graphics. Try to boot from your RX580 (as an image output device) and start the sgminer again.
Im start sgminer on RX480:
