Using voltage glitching to unleash the A100 in my mining card
A researcher discovered a voltage fault injection vulnerability in NVIDIA's GA100 GPU die that allows them to unlock disabled features on CMP 170HX mining cards, effectively converting them into A100-80G GPUs with enhanced performance. The unlocked cards achieve approximately 1.2x faster performance than retail A100s by enabling all functional streaming multiprocessors (~120-126 units) compared to NVIDIA's yield-safe 108 SMs, and also restore previously disabled features like NVLink, PCIe Gen4, and other capabilities.
