A tech enthusiast known as AssassinWarlord has upgraded a GeForce RTX 3070 graphics card to 16 GB of memory. To achieve this, he transplanted Samsung memory chips from a faulty AMD Radeon RX 6900 XT onto the Nvidia RTX 3070 PCB. This was reported by Ixbt.com .
Beyond soldering, the process required replacing a resistor on the board and installing a VRAM Config (8/16 GB) strap to ensure the system correctly identifies the 16 GB VRAM capacity. As a result, the card was fully recognized by standard GeForce software without needing custom drivers.
However, the modified card encountered issues: a black screen occurred when the GPU exited high load. This problem was linked to BIOS memory timings and was temporarily resolved by editing the DisableDynamicPstate parameter in the Windows registry.
The downside of this solution is that the card's idle power consumption increased to 70 W. Nevertheless, gaming performance saw a significant boost: in Marvel’s Spider-Man 2 at 4K Very High settings, the frame rate jumped from 20 fps to over 40 fps.
