Voltage injection unlocks mining card A100 functionality.
The story so far
Researchers have discovered a voltage fault injection vulnerability on the NVIDIA GA100 chip that allows operators to burn any fuses, converting the CMP 170HX 8GB graphics card into a device functionally equivalent to an A100-80G, unlocking which results in performance 1.2 times faster than the retail A100. The disabled features of the graphics card's CMP (such as NVLink, PCIe Gen4, NVJPG, NVDEC, MIG) can also be unlocked through this method.
