Mining card modified to unlock A100 performance

By PulseAugur Editorial · [1 sources] ·

A hardware enthusiast has successfully modified a CMP 170HX mining card to function as an A100-80G, unlocking its full 80GB of HBM memory and additional compute units. This involved a complex process of voltage fault injection to bypass fused-off memory and enable more Streaming Multiprocessors. The modified card reportedly achieves approximately 1.18 times the performance of a retail A100 for inference tasks, though the procedure is risky and time-consuming. AI
