Overview

• ASRock acknowledged that its BIOS PBO settings, specifically Electric Design Current and Thermal Design Current, caused over 108 Ryzen 9000 CPU failures on its AM5 motherboards
• BIOS 3.25 retunes EDC, TDC and shadow voltage parameters to prevent processors from drawing excessive amperage
• Users are urged to verify that BIOS 3.25 is installed on both new and existing ASRock AM5 boards rather than assuming it arrived factory-loaded
• ASRock reports no observed damage to any motherboards and is offering free shipping for RMAs along with assistance in returning affected CPUs to retailers
• Despite the firmware update and even with PBO disabled, multiple reports indicate that Ryzen 7 9800X3D chips are still failing on ASRock boards
