How to fix power delivery spikes on Galax B760M D4 Wi-Fi?
Walking through crowded streets was a nightmare; my CPU power was jumping wildly between 85W and 140W, causing a 110-135mV drop on the 12V rail. This tanked my FPS from 70 down to 32 instantly. I tried enabling Ultimate Performance mode in Windows, but that software tweak did absolutely nothing for the hardware-level instability—it just bloated my idle power draw. Total waste of time. I had to dive into the BIOS, navigated to Advanced Power Management, and switched the Load-Line Calibration from Auto to Level 2, while setting the CPU Core Voltage Offset to -0.04V. Checking HWInfo, the voltage ripple tightened up from 120-150mV to a rock steady 35-60mV. I actually hit two boot failures during the first attempt, but adding a tiny 0.01V bump to the memory voltage fixed it. VRM temps sat between 48-55℃, feeling just warm to the touch. After a three-hour stress test, frame times finally leveled out at 5.1-6.4ms. Still, the BIOS menu on this board is a bit clunky to navigate.
