Fixing power instability for Huntkey T600 in Civilization VII
My PC would just black screen and reboot during late-game massive war calculations; it felt like playing a lottery with my hardware. I tracked it down and found that the 12V rail on the Huntkey Blizzard T600 Colorful was dropping by 0.3V during 10-15ms CPU frequency spikes, triggering the motherboard's OCP. I tried capping the frame rate at 60 FPS, which reduced the crashes but made the calculations feel sluggish—a half-baked solution that just annoyed me more. I eventually went into Windows Advanced Power Settings $\rightarrow$ Processor Power Management and set the minimum state to 5% and maximum to 99% to kill those instant boost spikes, while disabling C-States in the BIOS. Using a voltage monitor, the 12V rail fluctuation narrowed from 11.7-12.3V down to 11.9-12.1V. My idle power draw jumped by about 18W, but the system is now rock steady. The PSU fan stays around 1200-1400 RPM, and RAM temps are holding at 58-63℃. The event viewer is finally clean of power errors, which is a huge weight off my shoulders.
