Voltage Glitching Unlocks CMP Mining Card Into 80GB A100

A researcher found a voltage fault-injection vulnerability on the GA100 die that allows arbitrary fuse blowing, converting a CMP 170HX 8GB mining card into an effective A100-80G. The unlocked cards expose all functional SMs (~120-126 vs. the yield-safe 108 in retail A100) and run about 1.2x faster than a retail A100, with NVLink, PCIe Gen4, NVJPG, NVDEC and MIG also unlockable.
