Igor Wallossek, chief editor of the German version of Tom's Hardware, spoke about the overclocking method for AMD Radeon RX 5700 and RX 5700 XT graphics cards. With it, the 7nm Navi 10 video core can be overclocked to 2.2-2.3 GHz. It is true that those who want to repeat the results of Igor should acquire a powerful cooling system, for example, use an EKWB block of water.
The AMD Radeon graphics driver uses the PowerPlay table, which is loaded into the Windows registry from the VGA BIOS chip, to control the power and speed of the video card's clock. By modifying the SoftPowerPlay table (SPPT), it is possible to change the standard parameters of the accelerator, in particular, to increase the limit of power, voltage or the maximum frequency of GPU.
For those who want to repeat the experiment, Igor prepared several modified registration files. Before using them, it is recommended to reinstall the driver after cleaning the system through the uninstall program of the screen driver (downloaded from the Guru3D server).
Due to previous changes to Shadow of The Tomb Raider, the Radeon RX 5700 XT reaches the heels of the Nvidia GeForce RTX 2080 and overlooks the excess of GeForce RTX 2070 Super. The power consumption of the old AMD Navi with it has grown to about 250 watts, occasionally up to 300-320 watts.
It can be expected that this method of overclocking be adopted by the owners of the Radeon RX 5700 and RX 5700 XT accelerators of alternative design, equipped with powerful cooling systems. On the shelves of these video cards, as we have already said, they will arrive before mid-August.
