Another Ryzen 7 7800X3D reportedly burns out despite AMD's voltage fix

Another Ryzen 7 7800X3D processor reportedly suffered catastrophic failure, despite AMD's recent voltage adjustment. A user named Magoth04 shared their experience on a Redditor forum, stating that their three-month-old CPU was destroyed while installed on a fully updated MSI PRO X870-P WIFI motherboard. The system unexpectedly shut down during gaming, then entered a boot loop before becoming completely inoperable.

Upon opening the case, both the CPU and motherboard exhibited visible burn marks, with the chip also showing slight swelling. AMD's EXPO setting was enabled, allowing the memory to run at its maximum speed, but the CPU was not overclocked and no manual voltage or current adjustments were made. The system was cooled by a 360mm AIO, and temperatures were deemed normal prior to the failure.

The Redditor mentioned that they had initiated an RMA process with AMD, but it remains uncertain if the warranty will be honored due to the chip being delidded before the request. This incident echoes previous reports of Ryzen 7 7800X3D processors burning out and damaging AM5 motherboards, a problem AMD initially addressed with a firmware update in 2023.

However, new swelling, boot-looping, and burnout reports have resurfaced in late 2024 and 2025, this time affecting the Ryzen 7 9800X3D. AMD attributes the earlier failures to motherboard manufacturers allegedly disregarding its recommended voltage and current limits. Some motherboard makers have acknowledged that aggressive PBO settings may contribute to the issue.

The exact cause of the latest failure remains uncertain, but the fixes implemented by AMD and the precautions taken by motherboard manufacturers may not be sufficient to prevent permanent damage in certain systems.
