ASRock has begun rolling out a new BIOS update for its AM5 motherboards, following recent concerns from users about Ryzen 9000-series CPU issues and broader stability problems. The company previously said it was investigating reports of CPU failures in cooperation with AMD, and this latest BIOS release is positioned as a key step toward improving platform reliability.
The update is being delivered as Beta BIOS version 4.07.AS01 for select 600-series and 800-series AM5 motherboards. It bundles AMD’s latest AGESA ComboAM5 PI 1.3.0.0a firmware, which is intended to strengthen overall system stability and platform compatibility.
Why this BIOS update matters for AM5 owners
In recent weeks, reports from the community have pointed to a rising number of Ryzen 9000 failures across different motherboard brands, but ASRock AM5 boards have drawn extra attention—particularly some 800-series models such as the X870 PRO RS. At the same time, complaints have also involved certain 600-series boards, suggesting the issue may not be limited to a single chipset generation.
ASRock says it has been reviewing the situation closely, monitoring feedback across online communities, and working directly with AMD through multiple rounds of collaboration. With AGESA 1.3.0.0a now available, ASRock has integrated it into this new BIOS to help address the kinds of problems users have been flagging.
What’s included in ASRock Beta BIOS 4.07.AS01
According to ASRock’s own change notes, the Beta BIOS focuses on three main improvements:
1. Updated AGESA to ComboAM5 PI 1.3.0.0a
2. Optimized memory compatibility
3. Resolved a boot failure that can occur on certain CPUs
The “boot failure” fix is expected to be especially important for users dealing with no-boot situations, including cases where a PC may refuse to boot after it has been running normally for a period of time. ASRock specifically recommends updating to this BIOS if you’ve encountered that behavior, as it’s designed to restore normal boot functionality.
Which CPUs are affected?
ASRock doesn’t list exact CPU models in the notes, but the wider discussion around these issues has heavily centered on Ryzen 9000-series processors. Community reporting has often highlighted the Ryzen 7 9800X3D, though other non-X3D Ryzen 9000 chips have also appeared in failure reports.
Will this BIOS fully prevent CPU failures?
It’s too early to say whether a Beta BIOS update will eliminate the problem entirely. However, updates that improve AGESA behavior, boot reliability, and memory stability can meaningfully reduce system-level instability and may help lower the risk of future issues for affected users.
If you’re using an ASRock AM5 motherboard—especially a 600-series or 800-series model—and you’ve experienced boot problems or instability, updating to the latest Beta BIOS version 4.07.AS01 may be a practical step while ASRock continues working toward a final, fully validated release.
