How to stop CPU throttling on Biostar B550MH in Warhammer 3?
Leading a massive army charge and seeing your FPS tank from 60 to 25 is an absolute mood killer. I checked the monitors and the VRMs on the Biostar B550MH were hitting 92-97℃, which forced the CPU to downclock from 4.2GHz to a pathetic 2.1GHz. I tried turning on 'Ultimate Performance' mode in Windows, but that just pushed the CPU over 100℃ and made the throttling even worse—basically throwing gasoline on a fire. I ended up gluing small aluminum heatsinks onto the VRM blocks and set the fan curve to hit 100% speed once it hits 70℃. In CPU-Z stress tests, the clocks finally stabilized between 3.8-4.1GHz. I actually bumped a capacitor while installing the heatsinks, so the PC wouldn't boot the first time, but a quick cable check fixed it. VRM temps are now 68-75℃. The fans sound like a jet engine, but the performance is actually consistent. Verified the frequency curve and it's finally flat. Fans are humming at 1400-1600RPM.
