A memory modification for the NVIDIA GeForce RTX 3070, which doubles its VRAM capacity, has demonstrated performance enhancements, particularly in the latest games.
Although this mod is more intricate than its predecessors due to the need for additional PCB soldering, the tested game exhibits a significant performance boost in terms of 1%, 0.1% lows, and average frame rates. Upgrading the NVIDIA GeForce RTX 3070 to 16 GB VRAM seems promising since NVIDIA had intended to release a similar card (RTX 3070 Ti 16 GB) but eventually canceled it. Although AMD marketing has recently criticized NVIDIA and emphasized VRAM, NVIDIA's launch of the GeForce RTX 4070 with 12 GB VRAM suggests that this trend won't change anytime soon. These modifications demonstrate the growing demand for more VRAM in certain games.
Memory modifications on graphics cards are increasingly common. Technicians and modders have been performing memory replacements on faulty video cards for years, and by swapping the memory and grounding specific resistors on the PCB, it's possible to deceive the card into supporting twice the memory capacity. The only drawback of this mod is the need to adjust GPU settings in the NVIDIA Control Panel, as modded GPUs might display errors like flickering or black screens unless set to high-performance 3D mode.
Once the graphics card supports this memory type, there should be no significant issues. Since there are no alterations to the GPU, it retains the same PCI ID, allowing all drivers to function and update seamlessly. This upgrade demands specialized hardware and extensive knowledge, especially for custom GPUs, such as the MSI card used in this instance. Upon testing the modified card with the Resident Evil 4 remake at very high settings, the 8GB VRAM constraint was eliminated, enabling memory allocation to exceed 8GB and significantly improving the framerate, particularly for 1% and 0.1% lows.
