A hacker says a cheap mining card hides 80GB of memory

A hardware tinkerer claims Nvidia's CMP 170HX, a crypto-mining card sold with 8GB, actually carries 80GB that is locked off by fuses. She says she unlocked it by voltage glitching and that the card then outran an A100 in her tests. None of this has been independently verified. If true, it would mean a discounted mining card is a data-centre accelerator held back only by a hardware lock. The claim shows how much capability chipmakers can deliberately disable in silicon.
