The latest BIOS versions of AGESA 1.2.0.5 affect the performance and stability of AMD Ryzen-based systems

There is a growing number of complaints online about BIOS firmware for motherboards designed for modern AMD Ryzen and Athlon processors. Their analysis suggests that the problem lies in the AGESA protocol version 1.2.0.5 code that AMD released about two months ago.

Remember that AGESA is a bootstrap protocol that motherboard manufacturers use to build BIOS firmware for their motherboard models. on the forums Reddit appeared quite a lot of comments, in which users of current AMD processors complain about a drop in system performance in Geekbench 5 and Cinebench R20 tests after installing new BIOS versions based on AGESA 1.2.0.5. Some also report an increase in CPU peak temperature after installing new firmware and also report new WHEA 19 errors in the OS event log, especially after CPU overclocking.

portal computer base Remarksthat installing AGESA 1.2.0.5 will result in a reduction in the maximum clock frequency of processors to 100 MHz for single-core workloads and to 150 MHz for multi-core workloads. In some cases, many BIOS functions associated with Precision Boost Overdrive technology are no longer available. There is also a reduction in the frequency of the FCLK bus and a drop in performance on the second quad-core CCX processor complex. In some cases, it is also noted that RAM cannot work in DDR4-3600 or higher mode, although the platform itself supports such memory via XMP profiles.

how writes techblog deskmodder, some of these problems already appeared in AGESA 1.2.0.4, except for bugs related to the operation of the processors themselves. Somehow all these bugs were migrated to the new AGESA 1.2.0.5 log and added to the list of new bugs .

Some manufacturers ignored the release of AGESA 1.2.0.5 and did not release new BIOS firmware based on it. Accordingly computer base, ASUS has completely stopped releasing new versions based on AGESA 1.2.0.5 and is waiting for the release of the AGESA 1.2.0.6b update. However, most motherboard manufacturers including Biostar, Gigabyte, and MSI still release updates based on AGESA 1.2.0.5. These firmwares are available on their official websites.

Owners of systems based on current Ryzen and Athlon processors using a BIOS based on AGESA 1.2.0.3c are recommended to refrain from updating to AGESA 1.2.0.4 and 1.2.0.5 and to wait until AMD AGESA 1.2 .0.6b released in which they wanted to believe that all of the above issues would be fixed.
