Looks like your system is corrupted.  All the words are gibberish. . . .


But seriously, most likely not a MB issue.  In my experience MB issues usually prevent windows from even seeing the card.  Most likely it is a driver issue.  I have several 6 and 7 card RX rigs with various asrock MBs including the proBTC.  I have found, with the RX series at least, the best drivers are the default ones that windows installs.  To fix your problem, run DDU or AMDs uninstaller.  Restart windows and let it install drivers.  I believe DDU turns off windows auto-detect driver setting, but you can run it again and click a button to enable.

Windows doesn't always detect all of your cards correctly, but they should still be listed somewhere in the device manager.  If they are incorrectly detected, just right click on them in device manager and select update driver.  It should correctly identify and install drivers.

If you have tried installing drivers from AMD several times, sometimes things just get too screwed up to fix (or at least will take too long to figure out).  Since it only takes me 10 mins to install win10 on an SSD, you may just want to reinstall.  Again, just let windows find its own drivers.  It does take a few mins to detect them all.  If all are not detected after 10 mins at idle, find them in device manager and click on the update drivers.

Unfortunately, I cannot get Claymore's to get temps and fan speeds, but they still all mine.

Happy mining.
