Using voltage glitching to unleash the A100 in my mining card

A security researcher has discovered a voltage glitching vulnerability in the GA100 die, allowing them to unlock features and increase performance on NVIDIA CMP 170HX 8GB cards by blowing arbitrary fuses. This has resulted in a ~1.2x performance boost compared to a retail A100 card. The researcher has made their findings publicly available and disclosed them to NVIDIA ahead of publication. The vulnerability is a result of NVIDIA's design choice to use fuses for product segmentation and security features, which can be relaxed by blowing more fuses.
