After purchasing an RTX 4090, one modder successfully doubled its VRAM capacity to 48 GB. Using a custom PCB and second-hand GDDR6X, along with a leaked Nvidia BIOS, they were able to achieve what seemed impossible. Notably, while many attempts to increase VRAM in graphics cards often fail, this particular case proves to be quite successful.
Key Takeaways:
- The modder, Vik-on, demonstrated the process of modifying the RTX 4090.
- Critical components included the custom PCB and a compatible memory solution.
- This achievement highlights the ongoing trend of graphics card modifications in the gaming community.
