GoKawiilResearcher uses voltage glitching to turn CMP 170HX mining GPU into an A100
A hardware researcher says they exploited a voltage fault-injection vulnerability in Nvidia's GA100 die to blow arbitrary fuses, enabling disabled features on a CMP 170HX mining card. The modified card reportedly exposes 80GB of memory, NVLink and PCIe Gen4, and activates more streaming multiprocessors than Nvidia enables on retail A100 cards, yielding roughly 1.18-1.2x higher FP16 throughput in benchmarks shown by the researcher.
