As a response to the Ryzen 7000X3D CPU burn-in, AMD has released AGESA 1.0.0.7 firmware to rescue these CPUs. currently, brands such as ASUS have released BETA BIOS updates for AM5 motherboards to prevent AMD Ryzen 7000 CPUs from burning up due to voltage issues.
According to KEPC, AMD AGESA 1.0.0.7 BIOS firmware goes beyond voltage limitations and has mandated that all Ryzen 7000 CPU users upgrade after the release of the AGESA 1.0.0.7 BIOS available update to avoid burn-in issues.
According to the motherboard manufacturer, the new firmware does not just limit the SOC voltage to 1.3V but also modifies the PROCHOT Control and PROCHOT Deassertion Ramp Time, two mechanisms related to thermal limiting, and Ryzen 7000X3D users must update to AGESA 1.0.0.7 BIOS as soon as possible.
According to the introduction, PROCHOT Control is a safety feature related to CBS and SMU COMMON, which is designed to avoid processor overheating. When the temperature of the processor reaches a critical value, the CPU or other system components will send a PROCHOT signal. The processor power is then reduced to lower the temperature and prevent possible loss.PROCHOT Deassertion Ramp Time is the definition of the time it takes for the processor to return to normal power after the PROCHOT overheat signal occurs. The time interval required for the processor to gradually increase its power and return to normal operation as the temperature returns below a critical value.
As it stands, AGESA 1.0.0.7 is more conservative with respect to PROCHOT, the voltage and temperature thresholds associated with PROCHOT and SOC / IMC will be much lower, and the time interval for consumption recovery will be longer. This means that CPU burn-in events are not only due to voltage, but may also include factors such as imperfect thermal management, but it will take some time to verify that the problem is actually solved.
AMD has already provided a BETA version to the motherboard maker for internal testing, and the official version is expected to be released on May 6.
The original AMD spokesperson’s comments are as follows:
We have identified the root cause of the problem and have released a new AGESA to enhance certain power controls on AM5 motherboards to prevent CPUs from running outside their specification limits, including capping the SOC voltage at 1.3V. None of these changes affect the ability of our Ryzen 7000 series processors to overclock memory using EXPO or XMP kits or improve performance using PBO technology to improve performance.
We expect all ODM partners to release new BIOS versions for their AM5 motherboards in the coming days. We recommend that all users check their motherboard manufacturer's website and update their BIOS to ensure that their system has the latest firmware.
Any CPU users who may be affected by this issue should contact AMD customer service support. Our customer service team is aware of the situation and is prioritizing these cases.
