I have two mining rigs with AMD RX 5700 XT and RX 5700 cards, as well, and both of those rigs are "dead" within a day of each other, within a few days of updating the drivers to newest Adrenaline a few weeks ago. They had been mining for over a year straight.
More worry-some, I have some rigs with RX 6600 cards, that after a recent driver update, they crashed, now the GPUs don't show up in Windows, even after a cold- boot.
So yeah, I've lost a NUMBER of RDNA1/RDNA2 cards, after a fairly recent driver update, seemingly. I have suspected a recent driver update, but was waiting for confirmation.
Edit: MSI Afterburner may have been installed on those rigs as well, and probably not as up-to-date as the drivers.
Could (maybe) be some sort of "bad" interaction between recent drivers and AB, that's pure speculation.
I've had fan-speed-stuck-at-zero (with GPU temps cresting 84C) problems with various Adrenaline drivers and the Nicehash client software running in Windows (seems like long-standing bug? Had that problem back in the day with R7 250X cards too), keeping AB running seems to sort of fix it.
Edit: IT APPEARS THAT I AM WRONG IN MY MISTAKEN ASSUMPTION.
The driver version that I updated to, on my RX 5700 XT x4 rig, was 22.11.1, not 22.11.2.
Also, that rig appears to now be working, so whatever was causing it to not power-on at all, seems to be working now. (PSU issue?)
The 2x RX 6600 rig with Intel mobo/CPU, will power-on, but neither of the RX 6600 is detected in Windows from a cold boot, which is concerning. I am going to order a new PSU for that one, as well as my single RX 5700 rig.
Edit: However, there was a thread on /r/NiceHash about RX 6600 cards dying fairly recently. Let me see if I can find it.
