ASRock confirms its BIOS settings are killing Ryzen CPUs, is fully committed to fixing any damaged motherboards

Biostar updates AM5 motherboard BIOS.

ASRock confirmed that it is responsible Ryzen 9000 failures plaguing ASRock motherboard owners. In a discussion between Gamers Nexus and ASRock's VP of motherboards, Chris Lee, the company confirmed its latest BIOS revision, 3.25, alters certain PBO settings to stop Ryzen 9000 chips from failing.

A few days ago, YouTuber Tech Yes City revealed that ASRock had allegedly solved its Ryzen 9000 problem. The issue surrounded three power and voltage-related functions, Electric Design Current (EDC) and Thermal Design Current (TDC) in Precision Boost Overdrive (PBO), and shadow voltages which were set too high in older ASRock firmware. ASRock has since provided BIOS version 3.25 to its armada of AM5 motherboards with re-tuned EDC, TDC, and shadow voltage settings to rectify the issue.
