Ryzen 5 7600X Owners Should Watch Out For BIOS Updates Based On This AGESA Firmware
Normally, on Ryzen platforms, we recommend applying new BIOS updates as soon as they're available. AMD puts continuous work into the AGESA firmware for its CPUs, and this sometimes results in major stability improvements or performance gains thanks to improved memory performance or feature support. Folks on a Ryzen 5 7600X may want to hold off, though, as the latest 1.0.0.4 AGESA supposedly has a bug that leaves certain Ryzen 5 7600X processors unable to boot.
This information originates with hardware enthusiast and sometimes-leaker chi11eddog (@g01d3nm4ng0 on Twitter), who reports that MSI and ASRock have pulled BIOS updates featuring AGESA 1.0.0.4. While chi11eddog seems uncertain as to the veracity of the report, they nevertheless remark that the reason is because Ryzen 5 7600X processors that are made from harvested processors with two CCDs become unbootable with the new firmware.
