YouTuber Paulo Gomes recently published a video showing how he modified a customer's RTX 3070, which used to be one of Nvidia's best graphics cards, with 16GB of GDDR6 memory. The modification resulted in serious performance improvements in the highly memory-intensive Resident Evil 4, where the 16GB mod was performing 9x better than the 8GB version in the 1% lows. (Resulting in significantly smoother gaming performance.)
Unlike previous memory mods we've seen on cards like the RTX 2070, Gomes' RTX 3070 mod required some additional PCB work to get the 16GB memory configuration working properly. The modder had to ground some of the resistors on the PCB to trick the graphics card into supporting the higher-capacity memory ICs that are required to double the VRAM capacity on the RTX 3070.
