Using voltage glitching to unleash the A100 in my mining card(blog.kate.land)

A researcher has discovered a voltage fault injection vulnerability in the GA100 die, allowing them to unlock restricted features on a CMP 170HX mining card, effectively converting it into an A100-80G card. By exploiting this vulnerability, the researcher was able to blow arbitrary fuses, enabling features such as a fully unlocked framebuffer, compute capabilities, PCIe Gen4, and NVLink, with the unlocked card performing approximately 1.2x faster than a retail A100. This method also allows for the unlocking of other previously disabled features like NVJPG, NVDEC, and MIG, demonstrating a significant breakthrough in bypassing NVIDIA's product segmentation and security controls.
