The user reported that the processor failed within an hour of being moved to an ASUS ROG Crosshair X670E Hero motherboard. The CPU had previously operated stably for about a year and a half on an ASRock X670E Taichi Carrara board.
The user, Reddit user SpecialistConcept423, stated that no manual overclocking or voltage adjustments were performed. Only a motherboard memory preset for SK Hynix 6200 MHz RAM own was enabled.
After saving settings and rebooting, the motherboard displayed a '00' Q-Code and failed to POST. Upon inspection, the same user found two brown marks on the CPU contacts, indicating severe damage.
The situation became more complex when the user tried an older Ryzen 5 8500G that had previously worked on the same board. This second processor also began reporting a '4D' code, suggesting the issue may be related to the motherboard itself.
The ASUS motherboard in question was not a new device; it had previously undergone USB-related repairs and a BIOS rewrite. The user has contacted AMD Brazil for an RMA request.
This is not the first instance of CPU failure on this motherboard model. A Ryzen 7 7800X3D was recently reported to have 'bulged and burned' on the same ROG Crosshair X670E Hero, and ASRock had previously admitted that aggressive PBO current limits in its BIOS were responsible for burning out a batch of Ryzen 9000 processors.
