Hello its my first post,
As u know we cant use i5 9400f on my motherboard even tho the socket is the same.
I know its pretty easy to flash a msi bios with a usb stick and m-flash feature in the bios.
Can someone make me that mod for me or link it, I am back from a long day of work and I dont find any of theses msi with 9400f method on google.
Thx yall for the help
