AMD AGESA Patch A BIOS Firmware Starts Rolling Out for X570 & B550 Motherboards Begins Rolling Out

AMD Ryzen 8000

Several AMD board partners have started to roll out the AGESA Patch A BIOS firmware for X570 ad B550 motherboards. This bios update provides an improvement in Ryzen 5000 CPU compatibility while also including fixes for USB issues that several users were facing.

Before this patch, AMD was to release its AGESA BIOS Firmware to address the USB connectivity issues faced by several users. But now, it is releasing the AGESA Patch A BIOS Firmware which also addresses the same issue while also improving compatibility with Ryzen 5000 series.

The AGESA Patch A BIOS Firmware is currently available for release by two motherboard makers, MSI and ASRock. Before, the AGESA BETA BIOS Firmware was expected to launch in early April to release a fix for the intermittent USB issues that plagued the AMD Ryzen 5000 (X570 / B550) platform.

AMD posted the following statement regarding the issue.

We would like to thank the community here on r/AMD for its assistance with logs and reports as we investigated the intermittent USB connectivity you highlighted. With your help, we believe we have isolated the root cause and developed a solution that addresses a range of reported symptoms, including (but not limited to): USB port dropout, USB 2.0 audio crackling (e.g., DAC/AMP combos), and USB/PCIe Gen 4 exclusion.

The issues seemed confined to Ryzen 3000 and 5000 series CPUs in 500- and 400-series motherboards (i.e., X570, X470, B550, and B450) and consisted of random dropouts for USB-connected devices. The complaints were across different types of USB devices like keyboard connection drops, issues with VR headsets, external storage devices, and others.

Currently, MSI is offering the AGESA Patch A BIOS update on 7 of its motherboards. Out of the 7, four are based on the AMD B550 chipset and the remaining three are based on the AMD X570 chipset. In addition to the AGESA Patch A BIOS, ASRock has also released AGESA BIOS firmware for its A520 motherboard lineup.
