ASRock confirms fix for some CPU boot failures
The statement lacks details, though.
ASRock has published a new statement announcing a “comprehensive” BIOS update for its AMD AM5 motherboards, positioned as a stability and compatibility update that also targets no-boot scenarios.
The company says it integrated AGESA 1.3.0.0a provided by AMD and released Beta BIOS version 4.07.AS01 . ASRock lists three headline items: ComboAM5 PI 1.3.0.0a, optimized memory compatibility, and a fix for a boot failure that occurs on “certain CPUs.”
We first spotted 4.07.AS01 appearing on ASRock’s beta BIOS listing over weekend and reported it immediately. This new press statement largely repeats the same limited description that already appeared in the changelog. It does not add a CPU list, reproduction conditions, or any platform segmentation beyond “AM5.”

The statement also does not say whether the fix is aimed specifically at Ryzen 9000 series processors. That is a gap because ASRock’s earlier February 5 update explicitly referenced “AMD Ryzen 9000 series” behavior and ongoing investigation with AMD.
ASRock’s wording suggests 4.07.AS01 is intended for at least some no-boot cases, including systems that stop booting after a period of normal operation. A BIOS update can address firmware-level compatibility and training problems, but it likely cannot recover a processor that is already nonfunctional. Some users did mention that they tried running ‘dead’ CPUs on other systems, but that did not fix them.
If your system did not randomly boot on ASRock motherboard and you had no idea why, perhaps this firmware update will fix the issue for you. ASRock motherboards allow users to flash new firmware regardless of whether the CPU is present, this only works through the BIOS Flashback feature, while the “Instant Flashback” requires UEFI access.
