MSI released their v1.3 BIOS for this motherboard to succeed the original v1.1 release.
...
Using 2 x 8GB DDR4-3200 Corsair memory, first I tried to put the DIMMs in their "AMP" mode to push it to the rated 3200MHz frequency. Unfortunately, like the earlier BIOS release, the system was not bootable. The BIOS POST code displayed on board was just F9 when attempting the AMP mode or manually pushing the memory frequency to DDR4-3200, regardless of additional voltage being fed to them. But, compared to before, I could now push the DIMMs up to DDR4-2933MHz where as before the system wasn't booting above DDR4-2133 for this particular board and memory combination.
