Modders use jumper wires and a custom BIOS to save a damaged RTX 4090 from the trash — resurrected Nvidia gaming GPU loses 4GB of VRAM to overcome terminal PCB sagging

Brazilian YouTuber Paulo Gomes, known for resurrecting damaged Nvidia GPUs, successfully revived an RTX 4090 with a damaged PCB by disabling a memory channel, reducing VRAM from 24GB to 20GB. Using jumper wires and a custom BIOS, they overcame PCB damage and a malfunctioning PWM circuit to restore the GPU's functionality, albeit with reduced performance. Despite losing 4GB of VRAM, the GPU was operational and benchmarked at around 10,300 points in 3DMark. Gomes also showcased a modified RTX 4090 with 48GB of VRAM, cautioning against pushing the GPU beyond its legitimate specs.
