2X Radeon Pro Duo, one no longer detected

I have two Radeon pro duos hooked up and up until today the setup was working great, low temps and high hashes.

All of a sudden one of the two cards is no longer detected... water pump, rad fan and card LEDs all work but no trace is device manager or the driver control panel.

Have not had any time to troubleshoot, but did I burn out the card?

I would run DDU in safe mode, reinstall the drivers you know were working, and see what happens

Had a similar issue, card was sagging (mine installed direct on motherboard) unplugged it/re-plugged it solved the issue.

Thanks, did this and it now works again!

What's your hashrate with those cards and your settings please?
