Overclocker turned an Nvidia video card with 8 GB into a monster with 80 GB of memory - for this she needed a scarf for 600 rubles.
Kate Land discovered that the CMP 170HX mining card actually has about 80GB of HBM memory, but Nvidia has limited software access to most of it. Using a home-made device for short-term voltage surges, she was able to bypass the protection and unlock almost the full potential of the chip.
As a result, the card showed 18% higher performance than the A100 server. According to Kate's observations, 80 GB could be opened in nine out of ten copies tested.
