AMD to roll out AGESA firmware update in early May to fix Ryzen 7000 series burn-in

Recently, news of sudden failures in Ryzen 7000X3D series processors has garnered the attention of numerous gamers, with the issue stemming from voltage levels escalating to unsafe degrees. AMD has previously issued two statements, acknowledging the problem, conducting investigations, and ensuring that processors operate within the correct voltage range. They have emphasized the importance of affected users contacting AMD support staff.

According to HKEPC, the new BIOS, built on AGESA microcode, not only imposes voltage limitations but also mandates users to perform firmware updates, in order to prevent further incidents of Ryzen 7000 series processors burning out. As per motherboard manufacturers, the updated BIOS not only caps SoC voltage at 1.3V but also modifies two thermal safety mechanisms related to heat limitations: PROCHOT Control and PROCHOT Deassertion Ramp Time.

PROCHOT Control is a safety feature associated with CBS and SMU COMMON. When the processor’s temperature reaches a critical level, the relevant components send a PROCHOT signal to reduce power and temperature, thereby preventing overheating and consequent damage. PROCHOT Deassertion Ramp Time defines the duration required for the processor to restore normal power after a PROCHOT overheating signal. As the temperature descends below the critical threshold, the time interval gradually increases to resume normal operation.

Evidently, the updated BIOS is more conservative regarding PROCHOT, with voltage and temperature thresholds related to PROCHOT and SOC/IMC being significantly reduced. The time interval for recovery consumption will also be extended, suggesting that factors such as inadequate thermal management may be involved in this incident. The emergency BIOS released by manufacturers simply limits SoC voltage without fully addressing the issue.

Furthermore, AMD has emphasized that the new BIOS will not impact users employing Ryzen 7000 series processors with EXPO or XMP memory, or those utilizing PBO technology to enhance performance. The official release of the updated BIOS is tentatively scheduled for May 6th.
