Foot horn doubling: Modified Radeon RX 5600 XT with 12 GB VRAM

In order to use the RX 5600 XT with a 12 GB configuration, a BIOS mod must be performed. In doing so, the modder used a hex editor to manipulate the values in the BIOS so that the faster 2GB ICs are recognized. Afterwards, the modified BIOS is flashed onto the card. While BIOS modding is still possible with some (older) AMD GPUs, this no longer applies to modern Nvidia GPUs.

The new modules in the 5600 XT have shown a massive performance increase in some tests. For example, in the Unigine Superposition test, which used a resolution of 10K to fully utilize the 12 GB memory configuration, the modified card scored 412 points compared to the 191 points scored by the original configuration. Although most games probably won’t benefit from this performance increase, the extra VRAM could be helpful for games that require more than 6 GB of video memory – as long as the GPU itself isn’t the bottleneck, which is becoming increasingly unlikely.

The changes have a much larger effect on AMD GPUs, as Gomes’ modification can be applied to the BIOS of these cards. Theoretically, this could mean that all AMD Radeon graphics cards could be upgraded with more video memory, as there are no known restrictions on BIOS modifications for AMD so far. In contrast, modern Nvidia GPUs do not allow BIOS modifications. However, it should be noted that special tools and skills are required for such modifications. However, if you need a graphics card with 12 GB or 24 GB of memory, it makes much more sense to invest in one of the current best graphics cards instead of trying to upgrade a three-year-old RX 5600 XT.
