Solving power delivery issues on the Jginyue B760M GAMING D4
This board is a total power hog when pushing high refresh rates. After an hour of gaming, my minimums would tank from 144 FPS down to 80 FPS—absolutely pathetic. The VRM module on the Jginyue B760M GAMING D4 builds up heat way too fast, triggering a throttle that makes the CPU clock swing between 4.8GHz and 4.2GHz. I tried undervolting in the BIOS, but that was a disaster; temps dropped, but my 1% lows hit 60 FPS. I eventually slapped on some small aftermarket heatsinks and optimized the case airflow to push the VRM fan speed to 80%, while disabling all CPU power-saving modes in Windows. HWInfo showed the VRM temps drop from a scary 88-102℃ to a stable 75-81℃. I actually had a scare where a heatsink almost shorted something due to the tight space, but some Kapton tape fixed it. CPU now sits at 72-78℃, and the frequency curve is finally flat. The input response feels instant again.
