A NVIDIA CMP 170HX voltage mod reportedly pushed a CMP-170HX from a cryptomining GPU into an A100 with 80GB of VRAM. The change matters because the card’s advertised 8GB state and the claimed 80GB state sit worlds apart on paper.
Tom's Hardware on Nvidia CMP
Tom's Hardware published the report on the hack. The headline says the method uses voltage glitching and carefully blows onboard fuses to unlock the full VRAM and shader modules.
That is the part readers should treat carefully. A fuse-based modification is not a software toggle, so the reported result implies hardware-level tampering rather than a simple configuration change.
A100 and 80GB of VRAM
The source says the modified card becomes a full-fat A100 with 80GB of VRAM. That comparison gives the story its practical edge, because it ties the mining card to a much higher-capacity configuration using the same hardware family named in the report.
The source also puts the card’s starting point at 8GB. That gap is the entire story here, since the reported mod is not a small gain but a jump from a limited mining part to a far larger memory footprint.
What Nvidia CMP changes
For readers tracking GPU hardware, the real issue is not the label swap. It is whether a CMP-170HX can be pushed into exposing resources that were likely disabled for product segmentation or binning.
The source text does not provide the full procedure. It also does not show an independent verification path for the transformation, so the headline’s claim about the A100 outcome still needs a method that can be reproduced and checked outside the write-up.
The unanswered question is simple: how exactly was the voltage glitching hack carried out, and was the 80GB result independently verified?
