Igor Wallossek of Igor'sLAB Germany postulated a method by which an AMD Radeon RX 5700 XT "Navi" graphics card can be made to run at clock-speeds of over 2.20 GHz (engine clock), thanks to custom SoftPowerPlay Tables (SPPTs) deployed by modifications to the Windows Registry. The AMD Radeon driver is designed such that it reads PowerPlay tables from the video-BIOS of an RX 5700-series graphics card the first time it's detected, and writes it onto the Windows Registry for quick-reference. This is called a SoftPowerPlay Table or SPPT. It's the modification of SPPTs that allows you to manipulate the power limits of RX 5700-series graphics cards, and achieve higher engine clocks than the 2150 MHz engine-clock limit of the RX 5700 XT, which is set at just 1850 MHz for the RX 5700.Wallossek's mod involves preparing your Windows Registry with a driver cleaner such as DDU, downloading and applying Registry files for various new power-limit targets you want. The table below details the various power-limit and clock headroom on offer from each kind of registry file. There's also a registry file that cleans up your Windows Registry of any SPPTs, if you decide to roll-back your mod. You can inspect a registry file by opening it in a plaintext viewer such as Notepad. Find links to the SPPT mods, and the Registry Cleanup in the source link below.
