RX 5700 XT Navi Crosses 2.2 GHz Thanks to Custom SoftPowerPlay Table Registry-Mod
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. You can also watch a video presentation by Wallossek in German language here. You make any changes to your machine at your own risk, be sure to have proper custom cooling for your graphics card.

So yeah, you could override it's power limits and core voltage(s), but nobody knows for how long that is capable or after how many running hours. Nvidia locks in it's chip for a good reason as well, because they proberly seen and tested that those chips on a higher power limit could show degradation on long term. Ofcourse, if i had a card and it would last at most 3 years, i'd go for it knowing i'll upgrade it anyway in the very near future. I've ramped up a AIO watercooler DIY on my RX590, knowing i'll upgrade it anyway once the 5700XT is more widely available hurting it's warranty. There's not much of a OC'ing headroom anyway on chips these days.
AMD is pretty much know for sqeezing out all it can.
Many people are just enthusiastic and lack knowledge; this voltage degradation thing is becoming a more important one as nodes get smaller. I've seen lots of people, enthusiast and knowledgeable or not, advocate that its 'just fine' to pump CPU volts all the way to max rated specs... for 24/7. The argument being that 'temps are low anyway so its fine'. Its really not. Voltage is voltage and it will degrade stuff faster; traces on the board too for example. So yeah, its good to take note of the ifs and buts when you OC. A lot of people just watch a Youtube, copy over some settings and think that's it.
Unlike their English-language site, I still count THW DE as a serious and trustworthy site. It's just too bad I can't read German :P
Thanks
