Some time ago, reports of Ryzen 7000 family processor failures began to appear online, and most of them related to Ryzen 7000X3D chips with an additional 3D V-Cache buffer.
As it turned out later, the cause of such cases was a significant increase in the supply voltage of the SoC during the operation of the platform. Moreover, these could be both situations with experiments during independent CPU overclocking, when the user is aware of their actions and their risks, and cases of normal use of EXPO profiles for high-speed memory modules, after which the SoC voltage automatically increased to 1.4 V and even more.
Excessive voltage could disable or damage internal thermal sensors and overheat protection. So the processor continued to work even with a significant increase in temperature. As a result, this could lead to burnout and damage not only to the CPU itself, but also to the AM5 connector of the motherboard.
Most of these cases concerned Ryzen 7000X3D chips, which are more sensitive to increasing SoC voltage, but there are risks for regular Ryzen 7000 models as well.
AMD responded promptly to reports of problems with the platform. The search for the root cause and ways to solve the problem did not take long. Message from the manufacturer:
We have root caused the issue and have already distributed a new AGESA that puts measures in place on certain power rails on AM5 motherboards to prevent the CPU from operating beyond its specification limits, including a cap on SOC voltage at 1.3 V. None of these changes affect the ability of our Ryzen 7000 Series processors to overclock memory using EXPO or XMP kits or boost performance using PBO technology.
We expect all of our ODM partners to release new BIOS for their AM5 boards over the next few days. We recommend all users to check their motherboard manufacturers website and update their BIOS to ensure their system has the most up to date software for their processor.
Anyone whose CPU may have been impacted by this issue should contact AMD customer support. Our customer service team is aware of the situation and prioritizing these cases.,
It’s best to secure your platforms by following AMD’s recommendations. This is especially true for owners of the new Ryzen 7000X3D chips that use high-speed memory with EXPO/XMP profiles.
