Why is my Soyo B550M losing voltage in RDR2?
After pushing the 4K Ultra Texture mods, the sheer level of detail in Saint Denis streets pushed my single-core load above 98% instantly. The VRM on the Soyo SY-Yanlong B550M just couldn't keep up, and I watched Vcore tank from 1.32V down to 1.18V in HWMonitor, which sent my frames plummeting from 60 to 32 FPS. I first tried lowering the ambient occlusion settings to ease the load, but the game looked like garbage and the stutters were still happening randomly—a total waste of time. I finally dove into the BIOS, switched the Load-Line Calibration (LLC) from Auto to Medium, and locked the VRM fan speed at 1800 RPM. Checking HWMonitor again, the VRM temps dropped from a scorching 92-98℃ to a more manageable 78-84℃, and the voltage swing tightened to within ±0.03V. It wasn't a smooth ride; the system hung twice during boot after the first LLC tweak, and I had to bump the SoC voltage to 1.1V to actually get it stable. Now, CPU temps sit at 68-75℃ and frame times are tight between 12-16ms. Ran a stress test to confirm the power delivery is finally in a steady state, and the gameplay feels buttery smooth.
