PowerColor Radeon RX 7900 XTX Overclocked to 3.25 GHz on LCS
When PowerColor launched the Liquid Satan Radeon RX 7900 XTX with a factory-installed water block, it mentioned the graphics card assured “final” overclocking, however did not elaborate. This week, well-known overclocker Roman “der8auer” Hartung lastly took this card for a check drive. It appears to have the ability to overclock very effectively: the GPU could be pushed to three.25 GHz – 3.39 GHz accordingly. YouTube video (through VideoCardz). The cardboard drew 650W on this case.
Clocked as much as 2,680 GHz with Unleashed BIOS mode enabled, PowerColor’s Liquid Satan Radeon RX 7900 XTX comes with a considerably increased GPU frequency out of the field than AMD’s reference design, making it among the best graphics playing cards on the market. it does.
On this mode, the graphics card attracts round 420W of energy and the graphics processor could be pushed to 2.95 GHz – 3.0 GHz. Whereas 3.0 GHz is a powerful clock for a GPU, it is nonetheless potential to go increased by growing the voltage of the chip.
Roman “der8auer” Hartung, as it’s not possible to extend the voltage of AMD’s RDNA 3-based GPUs and optimize their voltage curves utilizing software program like Extra Energy Instrument. ElmorLabs EVC2SE gadget that gives guide voltage management.
The default voltage of the AMD Navi 31 GPU on the Liquid Satan Radeon RX 7900 XTX graphics card is 1.030V. When the GPU voltage is elevated to 1.050V, it will possibly enhance itself to three.05 GHz, however the energy consumption will increase to 500W.
Der8auer elevated the voltages even additional (to 1.142V, for instance) pushing the GPU to three.25 GHz within the 3DMark TimeSpy Excessive check and three.39 GHz for gentle 3D rendering workloads. With enormously elevated GPU voltage and very excessive frequencies, the cardboard’s energy consumption from the slots elevated to 650W, which means the cardboard absorbs about 700W from the slot and auxiliary PCIe energy connectors.
Such a large overclock supplied about 28% additional efficiency over AMD’s reference Radeon RX 7900 XTX, whereas doing so with 83% increased energy; this clearly reveals that the GPU isn’t designed to deal with such frequencies. Nonetheless, from a pure overclocking perspective, 3.25 GHz to three.38 GHz is a powerful feat, because the acceleration for AMD’s Navi 31 GPU is 2.50 GHz.
