Enthusiast doubles RTX 3070 VRAM to 16GB using salvaged chips

A tech enthusiast has successfully modified an Nvidia RTX 3070 graphics card to include 16GB of VRAM, doubling the memory capacity of the original 8GB model. This was achieved by salvaging memory chips from a damaged AMD Radeon RX 6900 XT and integrating them onto the RTX 3070's PCB. The modded card reportedly doubles frame rates in VRAM-intensive games like Marvel's Spider-Man 2 at 4K resolution and includes a hardware switch to toggle between 8GB and 16GB modes. AI
