Modder Doubles RTX 3070 VRAM to 16GB, Finds Gains in Only a Few Games

Summary
[AssassinWarlord] upgraded an RTX 3070 from 8GB to 16GB of GDDR6 by transplanting eight Samsung memory chips, then benchmarked the card to measure real-world impact.
The mod required reballing salvaged RX 6900 XT memory, custom tooling and firmware-style tuning after power-state and power-draw changes initially failed to unlock stable higher-memory operation.
Benchmarks showed little change in most synthetic workloads because they were compute-bound, making GPU overclocking more effective than the VRAM increase alone.
A handful of games ran better by avoiding slow system-memory spillover, but the tester concluded the time, effort and complexity were not justified for most users.
