Double The VRAM Of An RTX 3070

A hardware enthusiast doubled the VRAM on an RTX 3070 from 8GB to 16GB by salvaging Samsung GDDR6 memory modules from a defective AMD RX6900XT, re-balling the chips using an AliExpress stencil and a 3D-printed holder, and tuning power and memory speed settings. Benchmarks showed minimal gains in synthetic workloads since most are compute-bound rather than memory-bound, though a few game titles showed noticeable improvement by reducing reliance on slower system memory. The conclusion is that the effort-to-performance ratio is poor for most users given how few games currently benefit.
