Voltage fault injection unlocks CMP 170HX mining card
What happened
Researchers found a voltage fault injection flaw in GA100 and used it to unlock the CMP 170HX 8GB mining card into a GPU functionally equivalent to an A100-80G, Hacker News reported on November 11. The reported post-unlock performance data puts FP16 FMA throughput at about 1.2 times a retail A100. Usable memory after unlocking depends on chip defects, so not every card can use the full 80GB; some are limited to 64GB.
