Modders Create Custom RTX 4090 Super with Significant Performance Gains

A team of tech enthusiasts has built an enhanced RTX 4090 using parts from other high-end Nvidia GPUs, achieving up to 16% real-world performance improvement.

The custom-built RTX 4090 Super uses the AD102 GPU from the RTX 4090 paired with faster memory from the RTX 3090 Ti HOF OC Lab Edition.
The modified card features dual 16-pin connectors and a PCB capable of handling higher voltages, contributing to its enhanced performance.
Benchmark tests show the custom card is up to 40% faster than the stock RTX 4090 with driver LoD tweaks, but actual gains are closer to 16%.
Nvidia is not expected to release an official RTX 4090 Super, focusing instead on its upcoming RTX 50-series Blackwell GPUs.
This DIY project highlights the potential for significant performance improvements through custom modifications and advanced cooling solutions.
