How to optimize power delivery for ASUS ROG STRIX Z890-A Snow?
This Snow edition board turns into a space heater under heavy load. The VRM temps spiked to 92℃ - 98℃, causing my CPU clock to tank from 5.2 GHz down to 3.1 GHz—an absolutely ridiculous performance drop. I tried cranking the fans in the BIOS, but it just sounded like a jet engine while the temps didn't budge. I stopped wasting time and went into the BIOS to set a CPU Core Voltage Offset of -0.05 V. I watched the core power draw drop from 280 W to 245 W in real-time. It wasn't a smooth ride; the system rebooted twice before I tweaked the Load-Line Calibration (LLC) to get it stable. Finally, the VRM temps dropped to 78℃ - 83℃ and the CPU stayed between 72℃ - 78℃, keeping performance swings within ±2%. It was a tedious process, but it stopped the embarrassing power-drop throttling. I no longer feel like I'm burning my hand when touching the top of the case. Exported logs show fans now stable at 1400 RPM - 1600 RPM.
