Stopping CPU frequency dips on Soyo SY-King Dragon H510M
The power management on this Soyo SY-King Dragon H510M is a complete disaster. The CPU frequency looks like an EKG, jumping wildly between 2.1GHz and 4.2GHz. These dips cause a noticeable hitch every few seconds while driving through the city, and it makes me want to smash my keyboard. I first tried 'Ultimate Performance' mode in Windows, but the CPU temp spiked to 98℃, triggering a thermal throttle that made things even worse—just a total rookie mistake. I went into the BIOS, completely disabled C-States and Intel SpeedStep, and locked the minimum CPU state to 90%. RTSS showed frame time variance drop from 12-45ms to a stable 14-18ms. The frequency curve is finally a straight line. The only downside is that idle power draw went up by 20W and the fans got louder, but I tweaked the fan curve to make it bearable. CPU temps are 68-75℃ and VRMs are 60-66℃. Backed up the BIOS profile so I don't have to do this again.
