TL;DR
A tech enthusiast has modded an RTX 3070 to 16GB VRAM by harvesting parts from defective graphics cards. The project demonstrates a successful hardware workaround that enhances gaming performance without requiring special drivers. Details remain emerging on long-term stability and broader applicability.
A PC enthusiast has successfully created a fully functional RTX 3070 with 16GB of VRAM by harvesting memory chips from defective graphics cards, demonstrating a significant hardware workaround that could interest high-end PC builders and modders.
The project was carried out by a user known as AssassinWarlord, who removed and reballing BGA memory chips from a damaged RTX 3070 and an AMD Radeon RX 6900 XT. The modified card was able to run with 16GB of VRAM, a configuration not originally supported by the RTX 3070. The mod involved replacing the memory chips with Samsung 8x 2GB ICs and making a resistor change to enable the 16GB mode. No additional software or driver modifications were needed for the card to operate in modern Windows environments and games. However, a stability issue was identified: the system would black screen after stress testing, attributed to BIOS memory timings. Applying a RegEdit tweak to disable dynamic P-states resolved this, though it increased idle power consumption to approximately 70W. In practical tests, the 16GB mod significantly improved performance in modern gaming, notably doubling frame rates in Marvel’s Spider-Man 2 at 4K settings, from around 20 fps to over 40 fps.
Why It Matters
This development is notable because it showcases a hardware-level workaround to increase VRAM capacity on a high-performance GPU, potentially extending the usability of damaged or defective cards. It also demonstrates that with advanced modding skills, enthusiasts can push hardware beyond standard specifications. The performance gains in VR-intensive games could influence future modding projects and hardware repair approaches, though stability and long-term reliability remain concerns.

Background
Graphics cards with damaged VRAM or GPU components are typically discarded or sold at a loss. Prior attempts to modify VRAM capacity have involved software hacks or BIOS edits, often with limited success or stability issues. This project builds on previous modding efforts but stands out due to the use of physically harvesting and reballing memory chips from damaged hardware. The modder’s process involved high-level soldering, reballing, and hardware adjustments, reflecting advanced technical skill. The achievement follows a trend among PC enthusiasts to extend hardware lifespan and performance through creative hardware modifications.
“The whole process was actually not that difficult, once you understand the hardware involved.”

Key Questions
Can this mod be used for everyday gaming?
While initial results are promising, stability issues and increased power consumption mean it may not be suitable for daily use without further refinement.
Does this modification void the GPU warranty?
Yes, physically modifying the hardware typically voids the warranty, and such modifications are recommended only for experienced users.
Is this process applicable to other GPUs?
Potentially, but it requires advanced soldering skills and detailed knowledge of the specific hardware. Success varies depending on the damage and hardware compatibility.
Will this increase VRAM capacity permanently?
Yes, the hardware modification physically increases VRAM capacity, but stability and power issues need to be addressed for long-term use.
