Engineer turns $2,500 Nvidia GPU into a $20,000 A100 equivalent

A techie named Kate used a custom-designed circuit board and voltage glitching techniques to bypass the security measures on an Nvidia CMP-170HX cryptomining graphics card. By manipulating the onboard fuse controller, she was able to access hardware features that are typically disabled at the factory. This modification allows the much cheaper mining card to perform at levels comparable to Nvidia's $20,000 A100 GPU with 80GB of VRAM. The exploit highlights security vulnerabilities in how hardware manufacturers fuse off components to sell lower-end models.
