Igor's Lab reports that AMD's new Ryzen 7000 burnout firmware fix, AGESA ComboAM5 patch 1.0.7.0, addresses further bugs surrounding Ryzen 7000's temperature control system. The new combo patch now sets a forced SoC voltage limit of 1.3v and packs in new SMU bug fixes to ensure the processors do not go beyond their temperature specifications.
AMD doesn't give us specific details on the issue, but apparently, there were optimization issues (in previous AGESA microcode updates) surrounding the temperature control system inside Ryzen 7000's SMU, causing the chip to operate incorrectly when hitting TJmax (i.e., its temperature ceiling). We don't know the extent of the potential damage this has caused, but there's a high likelihood this SMU bug was causing the Ryzen 7000 burnouts in conjunction with unsafe SoC voltages.
