When both CPUs appear in the same BIOS file, it's acceptable. MSI sometimes behaves oddly with these files and, according to what I recall, displays when BIOS support was added for a specific chip during the check. Any updates beyond that file should still be compatible. BIOS version 7C84v19 should handle both chips adequately.
