Fixing power delivery dips on Galax B360M-M.2 for RE Village?
The frames would suddenly tank from 60 FPS down to 15 FPS, and that jarring stutter is a nightmare when you're trying to sneak around. Looking at the logs, the VRMs on the Galax B360M-M.2 were hitting a 0.1V drop whenever the CPU boosted to 4.2 GHz, forcing the core clock to plummet. I first tried dropping the graphics to Medium, but the stuttering stayed, making me realize this was a low-level power delivery failure. I went into the BIOS Advanced Voltage settings, set the Load-Line Calibration (LLC) to Level 2, and tweaked the VCCIO to 1.1V. Monitoring with RTSS, my 1% lows climbed from 15 FPS to 42 FPS, and the frame time graph finally flattened out. I actually hit a memory parity error after the first tweak, so I had to downclock the RAM from 2666 MHz to 2400 MHz to stop the crashes. VRM temps are now 68℃ - 75℃ with fans screaming at 2100 RPM. 3DMark confirms it's stable now, though the fan noise is a bit much.
