ASUS has released a new beta BIOS which includes an AGESA Microcode update improving memory compatibility on their Crosshair VI Hero. According to ASUS, the updated microcode should enhance memory compatibility in combination with high clocking memory, adding support for 3466MHz, 3600MHz, 3733MHz, 3866MHz and 4000MHz memory multipliers without the need of BCLK overclocking.


AMD's Generic Encapsulated Software Architecture (AGESA), is a protocol that’s used in combination with AMD64 motherboards to initialise the system. This code is initializing the CPU cores, memory interface and HyperTransport controllers. Compared to what’s possible with Intel processors, AMD’s AM4 platform still requires a lot of additional tweaking to catch up in the memory department.

Looking for the BIOS it can’t yet be found in ASUS’ download section. We had to dig the forums to find the beta version. A non-beta version is expected in the near future. Thanks to this update, several users have already reported better memory compatibility, which is allowing Ryzen users to use a larger range of memory kits with their AMP profiles. It’s most likely that the better compatibility is the result of a combination of ASUS’ BIOS team working on optimizations as well as the AGESA Microcode update, but there is no information on this available.

We’re pretty sure ASUS isn’t the only one that has been working on releasing a BIOS update, taking advantage of the latest AGESA Microcode update. It’s a matter of days or weeks until other motherboard vendors will follow and release their news BIOS updates.
