AMD has confirmed that overclocking Threadripper causes a hidden fuse to blow, and this action does not void the warranty.

According to Tom's Hardware, it has been discovered that AMD Ryzen Threadripper 7000 series processors, known as Storm Peak, experience a blown fuse on the chip when overclocking is enabled. Unlike household circuit breakers, these fuses are specifically designed to blow only when a specific command is sent to the processor, and not due to system crashes or power spikes. The BIOS code in the Ryzen Threadripper 7000 reacts to the user-initiated change in the BIOS settings to enable overclocking, and a warning is displayed before the fuse is blown. This mechanism allows AMD to detect any indications of overclocking on the processor.

Contrary to what the messaging may imply, enabling overclocking does not automatically void all warranties. An AMD representative clarified that blowing the fuse by enabling overclocking does not void the warranty. However, AMD's standard Terms of Sale state that any damage resulting from overclocking or overvolting the processor is not covered by the warranty. Other unrelated issues may still qualify for warranty repair or replacement. Therefore, simply overclocking or overvolting the Ryzen Threadripper 7000 series CPU does not forfeit the owner's right to seek AMD's assistance. However, damages caused by overclocking, such as constant overheating that significantly reduces the CPU's lifespan, can void the warranty.
