The solution he found was apparently to modify a low-level NVIDIA power policy that isn't normally exposed to end-users. He says, "One of the important findings was that the power-management chain contains internal policy values that are not exposed through the normal consumer power-limit controls. This is the path that eventually led to a working experimental implementation." However, due to the method employed, the tool does require the user to disable Windows driver signature verification, which is yet another 'gotcha' of the mod.
As amusing as it is to see that the developer left his AI assistant's instructions for constructing his GitHub repository (which he didn't follow), it's a reminder both of the reliability concerns around "vibe"-coded software in production as well as of the incredible potential of AI software development. Since we spotted the story on this utility, the developer has already bumped the version from 1.5.0 to 1.8.0 with a new release on GitHub, suggesting that the pace of improvements is extremely rapid.
A few users on Reddit, where the author posted the above screenshot, lambasted the developer for taking ownership of what they claim is "100% AI generated work" and also for not structuring his code repository correctly (since all of the source is packed in a ZIP file, not properly viewable on GitHub). However, the majority of other users seem enthusiastic about his work, and several have already posted proof that it seems to work, with huge gains in 3DMark and other benchmarks.

M0rtis This is quite cool because if you look at some of the Power->Performance graphs for the RTX 5000 series GPUs they show that the GPUs are limited by their power envelope Many laptop modders have made serious gains by increasing their laptops power limits by shunt modding them. This might be a safer option to soldering resistors onto your PCB Reply
Roland Of Gilead M0rtis said: GPUs they show that the GPUs are limited by their power envelope Well, therin lies the problem. In an already insufficient thermal space like a laptop, and which often have limited cooling, this will not turn out nice. No amount of cooling pads, or thermal paste will be able to offload the heat. The fans in a low to midrange gaming laptop will be very loud. Maybe on the most expensive laptops, with extreme cooling, this could be of benefit, but even then those systems will run very hot. Reply

USAFRet 30 minute battery time, and melted case. Excellent! Reply
