ASRock Updates AM5 Firmware Again Amid Ryzen Boot Failure Reports

ASRock has released another BIOS update following last week’s firmware patch aimed at Ryzen 5 9600X failures and Ryzen 9000 No-POST reports. The new release continues efforts to stabilize affected AM5 systems.

According to VideoCardz, BIOS version 4.10 introduces AGESA ComboAM5 PI 1.3.0.0a, improved memory compatibility, and fixes for certain no-boot problems that can appear even after a system has been working normally.

BIOS 4.10 Brings AGESA ComboAM5 PI 1.3.0.0a

The updated firmware integrates AMD’s latest AGESA ComboAM5 PI 1.3.0.0a microcode. ASRock also highlights enhanced memory compatibility and overall platform stability improvements.

The company specifically references boot failures that may occur after a previously stable period. That pattern closely resembles a recently reported Ryzen 5 7500F failure on an ASRock board, where the system stopped posting despite earlier normal operation.

Affected Motherboards Include B650 and B850 Models

Supported boards include B650M-HDV/M.2, B850 Rock WiFi 7, B850M Challenger, B850M Challenger WiFi, and B850M Rock WiFi. Exact BIOS versions differ depending on the motherboard revision.

ASRock has not identified any specific Ryzen CPU model as the root cause and has not linked the issue to a particular Ryzen generation. The company positions the update as a firmware-level fix rather than a confirmation of hardware defects.

If your system still boots normally, ASRock recommends updating through the UEFI Instant Flash utility. Users must download the correct BIOS file for their exact motherboard model and revision before proceeding.

For systems that fail to POST, only motherboards with BIOS Flashback support can typically be updated without a functioning CPU. In that case, users can apply the update using PSU power and the dedicated Flashback USB port and button.

ASRock notes that while the BIOS fix may resolve boot instability or POST errors, it is unlikely to restore CPUs that fail to POST across multiple different motherboards.

Users should carefully confirm their motherboard model and hardware revision before flashing. Using an incorrect BIOS file can result in compatibility issues or a failed update.

With this second firmware release in quick succession, ASRock continues working to address Ryzen-related boot concerns across its AM5 lineup.
