Via a forum post, MSI confirmed its motherboards have issues with overclocking the Infinity Fabric of AMD's Ryzen 5000 series processors. With the official BIOS version, which was released on November 4th, it's not possible to clock Infinity Fabric beyond 1600MHz on some processors. BIOS beta version 7C35 or 7C36 lessens the problem.

Affected motherboards include the X570 Ace, Unify and Creation series. Citing posts from the Asian ChipHell forum, MSI claims motherboards from Gigabyte and ASUS are also affected.
The problem means that in combination with the official bios (with the release date of November 4, 2020) for the Vermeer CPUs (Ryzen 5000 on AM4), the infinity fabric cannot go faster than 1,600 MHz. It occurs with some processors, but the manufacturer does not specify which chips are problematic and which are not. With the beta bios with 7C35 or 7C36 in the name, the problem is less, with this update chips are able to go up to 1,900 MHz. Faster speeds would also be possible, although this depends on chip quality. Also, updating the bios is not necessary if you can reach a fclk speed of 1900 MHz without this beta bios.
