Using voltage glitching to unleash the A100 in my mining card

Using voltage glitching to unleash the A100 in my mining card

Brief overview

Researchers have discovered a voltage fault injection vulnerability on the NVIDIA GA100 chip that allows operators to burn any fuses, converting the CMP 170HX 8GB graphics card into a device functionally equivalent to an A100-80G, unlocking which results in performance 1.2 times faster than the retail A100. The disabled features of this graphics card's CMP (such as NVLink, PCIe Gen4, NVJPG, NVDEC, MIG) can also be unlocked through this method.
