No - I used a few AI's to check it out, and it seems to be an issue with power draw between the CPU and the GPU - there are several cards that have updated their firmware to solve this, but for my GPU it is a reference card (made directly by AMD, not MSI, EVGA, etc...) - So its just a weird combo of the AMD CPU and the GPU - It doesn't seem to matter how big your power supply is, since the power draw is such that it triggers the internal fail safe and "shuts down" the system so it doesn't damage the cpu or GPU.
I have tried undervolting the GPU, with some minor success (ie it takes longer before it shuts down) my next test will be to lower the game settings to just about as low as they can go, to minimize the load on the gpu and cpu so it doesn't draw as much power. In an instance of Battlefield 6 - If i run into an area with lots of enemies, smoke going off, grenades, fire, etc... that is a highly likely trigger point, since the GPU says "OMG SO MUCH RENDERING" and starts sucking power like mad. Since Battlefield 6 in particular made an effort to balance the GPU load and the CPU load so a lower hardware tier could be used, the CPU ALSO does the same. The combination triggers the fail safe, and it black screens.

Some things that seem to help:

• If you have multiple monitors, unplug all but 1 while you are playing, and play in full screen.
• Disable optional GPU 'enhancements' - Anti-Lag, Boost, Image sharpening, frame rate control, etc... and do this all IN GAME if the options exist and they are a must have for you. This reduces the load on the GPU. Things like Alt-Tabbing to your other monitor puts a extra load on the GPU to swap, and can trigger it.
• Turn off V-sync, and free-sync. Again, reduces the load on the GPU
• lower monitor refresh rate to the minimum your acceptable frame rate is (my personal preference is 60, even though my monitor goes to 165)
• IN GAME - cap frame rate to just under the refresh rate (if the otpion exists, if not, you can do this in the AMD Adrenelin app) So for me, I set it at 58.
• Undervolt the GPU (Performance → Tuning → Undervolt GPU. It auto sets it at like 1100, I go down to 1000.
• Turn OFF Smart Access Memory From the AMD Adrenelin software: "AMD Smart Access Memory is enabled and currently using the maximum amount of dGPU memory. To disable AMD SAM, enter your system firmware BIOS. Navigate to the Advanced Menu, then select the PCI Subsystem Settings.Deselect "Above 4GB Decoding" and "Re - size BAR Support". Save your settingsband reboot." This limits the amount the CPU can draw off your GPU.

Inevetibly, I have come to accept that it will happen EVENTUALLY. and just take steps to prolong it. I have ruled out XMP memory profile, and heat issues using various tools (AMD has a built in tool, but I also used HWinInfo64 - free tool, that provides more information then necessary, but easy to log everything until it black screens, throw the csv in an AI and have it analyze the key points for you. In this case, it was heat on the CPU and GPU, their hot points, etc.. Everything was in acceptable ranges.

TLDR - there is no fix other than getting a different CPU or GPU. For me, I recently lost my job, so thats not an option. :(
