More Community Driven Due to hard-lock, PowerTool For AMD GPUs Will Not Support RDNA 3 GPUs; Users Must Pay For Power Limits & Features


Igor Wallosek of Igor’s Lab is one of the programmers and hardware enthusiasts that created the MorePowerTool, also known as MPT. Setting OC restrictions, Frequency / Power curves, and fan speeds are just a few of the functions that this tool adds to AMD’s Wattman OC suite. During the RDNA 1 and RDNA 2 generations, this utility came in quite handy because it allowed customers to get more performance and clocks out of their products. However, during the most recent generation, AMD also aggressively locked down their GPUs.

The Navi 21 XTXH silicon release marginally increased the frequency limit of the AMD Radeon RX 6900 XT to 3 GHz, and the 6950 XT release further increased it to 5 GHz. However, these cards came with a large premium, so you had to spend extra money if you wanted the greatest overclocking chip. AMD has essentially locked everything now with RDNA 3, according to hellm from Hardwareluxx’s community:

Perhaps someone read my most recent entry on the MPT thread at Igor, but we—that is, mostly gupsterg and his contacts—have finally reached some conclusions. Veii, of course, has already decided on his contribution, and we all concur.

Almost everything is secured twice and three times. Firmware and drivers would need to be rewritten, which we are unable to do. even not with Linux. Therefore, there won’t be an MPT for RDNA3.
This time, AMD really messed it up.

By the way, PSP is also used to manage firmware flashing, so we can no longer simply exploit AMD software to allow you to flash it. seems to only function with a third-party programmer.

This implies that you must pay for your power restrictions and features today and that you cannot activate or change them afterwards.

Everything for the RDNA 3 line of GPUs, as the user states, is double- and triple-secured, and the only workaround is to rebuild the firmware, which they are unable to accomplish (not even in Linux). Although that doesn’t sound like a wise move on AMD’s part, this is sadly where things are going. It appears that GPU manufacturers will charge more for top-binned silicon, and consumers will still have to pay extra if they want to use particular overclocking or tuning functions.

There have been several issues with the introduction of AMD’s brand-new RDNA 3 graphics architecture and the corresponding Radeon RX 7900 XTX/XT graphics card. There have been numerous problems with the drivers’ readiness and the supported features, and the reference models have shipped with defective coolers to a number of consumers. We hope that team red can get things under control so that the community can continue to take advantage of the features and tuning choices they previously enjoyed.
