AGESA 1.0.7.0 Fixes Temperature Control Issues Causing Ryzen 7000 Burns
Igor’s Lab reports AMD’s new Ryzen 7000 burnout firmware repair, AGESA ComboAM5 patch 1.0.7.0, addresses different bugs associated to the Ryzen 7000’s temperature management system. The brand new combo patch now units a compulsory SoC voltage restrict of 1.3v and contains new SMU bug fixes to make sure processors do not transcend the temperature specs.
AMD does not give us particulars on the matter, however apparently there have been optimization points (in earlier AGESA microcode updates) surrounding the temperature management system contained in the Ryzen 7000’s SMU, inflicting the chip to misbehave when it hits TJmax (i.e. its temperature). ceiling). We do not know the extent of potential injury this causes, but it surely’s extremely probably that this SMU bug will trigger Ryzen 7000 burnout along with unsafe SoC voltages.
Downside with Ryzen 7000s particularly CBS SMU_COMMON ‘PROCHOT Management’ and PROCHOT Launch Ramp Time. The primary is a thermal security mechanism that protects the CPU from overheating when the CPU reaches its focused thermal restrict. The SMU will emit a PROCHOT sign that can cut back CPU energy and frequency to remain beneath the thermal threshold and forestall potential injury.
The latter is the reverse of the earlier mechanism that permits the CPU to extend energy and frequency once more when the thermal restrict is just not reached (and the PROCHOT sign is just not lively). This method is time-based, so the CPU can progressively improve energy and clock speeds when there’s a temperature hole. It is a core operate of the SMU in order that CPU clock speeds do not bounce in every single place because of temperature fluctuations, leading to inconsistent efficiency.
In accordance with AMD patch notes in Igor’s report, with earlier AGESA code updates, each mechanisms had no impact on Ryzen 7000 CPUs. We do not know precisely what this implies, however apparently the SMU was permitting the CPU to at the very least barely exceed TJmax and someway inflicting efficiency points with the CPU beneath TJmax.
Once more, we do not know the way intensive this matter has develop into. Nonetheless, it is a sufficiently big problem for us that we strongly suggest that each one Ryzen 7000 customers improve their motherboard BIOS/UEFI to a model with AMD’s AGESA ComboAM5 patch 1.0.7.0 as quickly as potential. The firmware replace additionally supplies many different bug fixes, together with improved boot occasions, deep sleep fixes, curve optimizer fixes, and quite a few DDR5 reminiscence bug fixes.
