AMD is scheduled to release its new AGESA 220.127.116.11 update to Ryzen board partners in mid-November. This comes via a Gigabyte staff member who further revealed that the microcode could be called AGESA 18.104.22.168 instead of 22.214.171.124. The release may result in further bugs as the company extends CPU and APU support on the AM4 platform.
Since the launch of their Ryzen processors, AMD has been improving the platform’s memory support and performance through the release of microcode updates known as AMD Generic Encapsulated Software Architecture (AGESA). Supplied as an essential component of the motherboard BIOSes, AGESA is responsible for initializing x86-64 processors during boot time.
The previously-released AGESA update vastly improved memory compatibility of processors along with offering a fix for the FMA3 hard-crash bug in Zen. The new AGESA 126.96.36.199 is expected to start rolling out in November, however, it could be one to watch for a while prior to installing.
In response to an Overclock.net forums question about the Crosshair VI series motherboard, Asus employee and professional overclocker Elmor warned: “AMD has also changed the entire BIOS base structure [in AGESA 188.8.131.52] so we have to do a lot of work to port everything to the new version, which may result in further bugs.”
According to Elmor, the sudden shift in the way AMD’s BIOS operates is designed to make it easier to add support for upcoming socket AM4 chips, such as the Raven Ridge APUs, and the second generation Ryzen Pinnacle Ridge CPUs.
What’s more, the changes introduced with the AGESA 184.108.40.206 could not only cause new bugs but also result in a delay before the firmware updates are made available to the end user. That was expected after all board makers will have to work harder to implement the changes and iron out as many kinks as possible prior to release.
