Kate's writeup is wild. The 8GB CMP 170HX apparently ships with ~80GB of HBM onboard, just fused off. Software unlocks got people to 64GB. She used voltage fault injection to get past the fuse lock, then enabled all the working SMs (120-126 vs the 108 NVIDIA ships on A100). Her numbers: 85.9 TFLOP/s FP16 vs 72.5 on a retail A100, with the full 80GB usable for inference. NVLink and PCIe Gen4 come back too. Not a weekend mod though: board wiring, a custom STM32 glitcher, 1 to 48 hrs of glitching per card, and one of her ten cards only had 64GB intact. Would you actually risk bricking one of these for 80GB of HBM, or is this firmly "cool, not for me"? https://blog.kate.land/posts/using-voltage-glitching-to-unlock-the-a100/   submitted by   /u/jomic01 [link]   [comments]
