Go to YouTube and search redpandamining and 5600xt. There is a link in the video to download the MSI BIOS for 5600XT and you need to use RBE to change the subID to match your card then flash.
I use:
1100 MHZ core speed
700MHz core mV (BIOS modded) use 800 if yours is stock
Memory: 910 for Samsung memory, 930 for micron memory
