Have a 5 card rig (win10, rx470 4gb) that's been running fine for months. Suddenly dropped out, and now Claymore exits because 'no amd cards in list'. Cards are present and correct in Win10 device manager, no errors.
Tried older drivers, tried newer drivers. Removed win10 updates. Tried new OpenCL package. Any ideas anyone? Is there a way to force the OpenCL list to update? Much appreciated in advance!
I actually had the same problem. If you have not solved this, what worked for me was downloading DDU (Display Driver Uninstaller) and uninstalling the gpu drivers with that software, then re-installing the drivers. Worth testing atleast if you have not already.
