Seems like we have similar builds and the same GPU. I know on one of the driver updates, (25.10.2 Release Notes), it specifically talks about bf6 crashes and support for this game on these GPUs, and when I get the error message it specifically calls out that driver number. AMD suggests using the cleanup utility (AMD Cleanup Utility ) to erase any previous drivers before updating to the new one. I will need to give this a try and see if it helps.
As far as EXPO goes, I did consider it but everyone says that it should be stable at 6000 MT/s, and also why would it give me a DirectX error with my GPU in it as well ? I an not sure how memory would affect the GPU itself.
I will have to give it some time and play the game and see if using the utility and then redownloading the newest adrenaline version solves the crashing.
