Hello, this is my first post here. I will describe everything that happened before the problem occurred.
So, my GPU is a Powercolor PCS+ R9 290 (4GB). I yesterday updated MSI Afterburner to the latest version. My core/memory clocks were these:
I then updated to the latest GPU drivers. (17.4.3). I restarted my PC and I opened up a game (Specifically S.T.A.L.K.E.R. Call of Pripyat) and a few minutes later it froze and I got a bluescreen.
When I restarted I noticed that my profiles in MSI Afterburner had changed. Core clock was set to 1040Mhz and Memory to 1350Mhz. (These are the default clocks that come with the Powercolor PCS+ version. I set them to the default R9 290 reference clocks myself back in 2014 when I got the GPU though). I tried resetting them in any way possible but they kept changing back to the same number. I checked HWInfo64 to see if the numbers were just a bug but even there, it was the same.
So I tried using the Radeon Wattman to change the speeds. I set the states to 947 for the Core clock and 1250 for the Memory. I hit apply, core clock resets to 1040 but memory stays to 1250.
I have also noticed that my memory clock drops from 1250 to 150 randomly. It's not stable.
I have no idea what's wrong. There is no way this could be damage caused by high temperatures as I always make sure it never goes above 80c even in the hottest summer days.
Anyone could please provide some help?
Uninstall MSI Afterburner as that looks to be battling for control with Wattman over your clock speeds. Once you've removed it, download DDU to clear out your current drivers and then perform a clean install.
