How to bypass the power wall on Maxsun MS-Challenger B850M-K?
This motherboard felt like it was putting handcuffs on my CPU. While running through the open world, my clocks would tank from 4.8GHz down to 2.2GHz, turning the game into a slideshow. The default PL1 power limit on the Maxsun MS-Challenger B850M-K is way too conservative. I tried taking the side panel off my case, which dropped temps by 5℃, but the clock speed stayed locked—physical cooling does nothing against a hard power limit. I finally went into the BIOS and set both PL1 and PL2 to 4095W (essentially unlimited) and locked my fans to 1800 RPM. Using RTSS, I saw my minimums jump from 35 FPS back up to 62 FPS. The catch is that the VRM temps spiked to 92℃ immediately after unlocking, so I had to zip-tie a tiny 40mm fan directly onto the heatsinks to keep it from throttling. CPU temps stayed between 78-84℃. I exported the frequency curves, and the fans are now humming steadily at 1400-1600 RPM.
