AMD's current AGESA 1.0.0.7 BIOS firmware seems to be riddled with issues and comes with various memory compatibility bugs.
Following the recent reports of AMD Ryzen 7000 CPUs and AM5 motherboards burning up, AMD and its partners issued a quick but temporary fix for the platform that lowered the SoC voltage to 1.3V. The red team also confirmed that a more refined BIOS will be shipping in early May that will introduce additional thermal limits to eliminate any possible voltage burnouts on the new chips.
While the majority of AMD's partners issued an update through AGESA 1.0.0.6 BIOS firmware, ASUS decided to go with a BETA release of AGESA 1.0.0.7 BIOS firmware. However, the actual AMD AGESA 1.0.0.7 BIOS firmware release may have to wait since the current version has various flaws & issues including buggy memory overclocking and compatibility.
AMD has confirmed with board partners about the existence of these issues and is now working on a newer 1.0.9.0 firmware (internal naming) which is expected to mitigate these issues but there's no guarantee that all of it will be fixed. It is advised that all board vendors who were planning to roll out BIOS based on the existing 1.0.7.0 firmware roll back to an older version for now.
This means that you have to stick with the latest AGESA 1.0.0.6 updates that include voltage limits but no thermal limits which are included in the internal 1.0.7.0 revision.
According to leaker, chi11eddog, the current AGESA 1.0.0.7 BIOS firmware can only offer support for DDR5-4400 speeds compared to DDR5-6000 speeds on the AGESA 1.0.0.6 BIOS. This means that EXPO has been limited and the only way to enjoy faster memory speeds is to use the older AGESA firmware.
