thanks try win 10 did not know if i had to Chang something in the mb bios have not used amd for a long time
It's better to use Windows 10 because of the support and updates
It's not necessary to change anything on Motherboard bios, you can use default settings
AMD 5600XT have bios mod if you want
40Mhs without Biosmod, only tweaking memory overclock and reducing core voltage
43Mhs with Bios mod, but you'll probably lose warranty
