How to stop thermal throttling on Maxsun B850ITX WIFI ICE?
During intense cavalry charges, my frame rate would suddenly tank from 90 FPS down to 35 FPS, making the controls feel completely unresponsive. Checking HWInfo, I saw the VRM temperatures on the Maxsun B850ITX spiking to 102-108℃ within three minutes, which triggered a brutal thermal throttle that slashed my CPU clock from 5.2 GHz to 2.8 GHz. I first tried cranking up the case fans, but that only dropped the temp by 5℃ and made my room sound like a server farm—it was a total nightmare. I eventually dove into the BIOS, navigated to Advanced → Voltage, and set the CPU Core Voltage Offset to -0.050V, while switching the VRM fan curve to a more aggressive stepped mode. With HWInfo monitoring, the VRM temps finally settled between 88-92℃ and the clocks stabilized at 4.8-5.1 GHz. I actually tried -0.100V at first, but the system crashed twice before I backed it off to -0.050V. Now, the CPU core stays between 76-82℃, power draw is down by about 15 Watts, and frame times are rock steady at 5.1-6.4ms. It's a bit of a struggle to balance, but it works.
