Extreme Radeon RX 7900 XTX overclocking to 3.2 GHz

Der8auer finally puts one of the most capable custom Radeon RX 7900 XTX GPUs through a series of tests to achieve the highest performance.

PowerColor Liquid Devil is a custom graphics card equipped with three 8-pin power connectors, a high-end 17-phase VRM board design and a full cover water block designed by EK. In proper hands and some crafty tools, this combination could unleash the full potential of the Navi 31 GPU. Precisely this was Der8auer’s goal in his latest video.

Extreme overclocking typically involves customizations to the board but not necessarily exotic cooling, such as liquid nitrogen. In this case, such cooling wasn’t required because the card is already shipping with a liquid-cooling block. However, Der8auer used EVC2SE module from ElmorLabs. This is a special DIY kit that can control the voltage rails and easily trick the GPU into non-standard operation.

The PowerColor RX 7900 XT GPU already pulls 420W with “Unleashed” BIOS selected and manual overclocking applied through MSI Afterburner software. The GPU clock can go as high as 2.95 GHz to 3.0 GHz. The power measurement tool shows the card surpassing 400W already which only considers power connectors.

With EVC2SE changes applied, the voltage can be increased from 1.030V up to 1.050V, which has an immediate effect on the frequency and power as well. The card’s GPU can now boost up to 3.05 GHz and 500 watts of power.

In the end, Der8auer managed to tune the GPU to run at 3.25 GHz during the 3DMark TimeSpy test (3.38 GHz in light render workload). The board power has skyrocketed to 650W, and so has the temperature, reaching as high as 100°C.

More importantly, the RX 7900 XTX GPU has gained 28% performance in TimeSpy, compared to the stock AMD MBA (Made by AMD GPU), which is sadly still not enough to beat NVIDIA’s RTX 4090. That said, this video may explain why AMD opted not to launch a halo product with increased power, just to compete with flagship NVIDIA GPU.
