A recent experiment demonstrated that modifying the memory of Nvidia GeForce RTX 4070 Ti Super graphics cards can significantly enhance their performance. Brazilian YouTubers, including hardware tinkerer Paulo Gomes and the overclocking team at TecLab, undertook this project by replacing the stock 21 Gbps VRAM with faster 26 Gbps chips and overclocking the GPU using the original cooling systems. During their tests, both groups utilized the Unigine Superposition 8K benchmark, a tool known for its rigorous hardware stability testing and advanced graphics features like screen-space ray-traced global illumination and dynamic lighting. The results were compelling, as both modified cards outperformed the higher-tier Nvidia RTX 4080, with TecLab scoring 9,133 and Paulo Gomes achieving 8,870.

This modification process was not straightforward; it involved desoldering the original VRAM chips and soldering on new, faster ones. Additionally, adjustments were necessary to support these faster memory chips without causing firmware or software issues. The successful implementation of these mods was supported by the expertise and resources of their sponsors—Manli and Galax, respectively, which provided the necessary technical backing.

The YouTubers conducted their tests using the stock triple-fan coolers that came with their respective graphics cards, ensuring that neither team had a cooling advantage. This setup highlights the potential for significant performance boosts through hardware modifications, even when using standard cooling solutions.
