How to stop power delivery dips on ASUS TUF B760M-PLUS D4?
It was brutal—my frames would suddenly tank from 144 down to 42 in the middle of a fight, which is basically a death sentence in a tactical shooter. Looking at the logs, the VRM on my ASUS TUF Gaming B760M-PLUS D4 was hitting a 0.05V vdroop during peak loads, making the CPU core clock jump erratically between 4.8GHz and 3.2GHz. I tried enabling 'Ultimate Performance' mode in Windows, but that software tweak did absolutely nothing for the hardware-level voltage instability. I had to dive into the BIOS and change the Load-Line Calibration to L2 mode, then bumped the Vcore offset by 0.04V. During an AIDA64 stress test, the CPU stayed stable between 72-78℃, and voltage fluctuations tightened to within +/- 0.01V. I actually overshot the voltage once and triggered a thermal shutdown, which was a wake-up call to recalibrate my fan curves. Now the VRM area stays around 55-62℃ and that annoying coil whine has mostly vanished. System logs confirm the voltage curve is finally flat, with board temps holding at 55-62℃.
