Why does my ROG STRIX X870-A drop frames in FF XV?
Whenever I unleash massive magic attacks, my frame rate tanks from 110 FPS down to 55 FPS, and the judder is just jarring. After digging into the telemetry, I found that with PBO enabled, the core voltage on the ASUS ROG STRIX X870-A was dipping violently between 1.12V and 1.18V under transient loads, forcing the CPU to downclock. I wasted some time switching the Windows power plan to Ultimate Performance, but the stutters persisted, which was honestly frustrating. I eventually dove into the BIOS, manually set the Load-Line Calibration to L3 mode, and added a +0.02V voltage offset. Monitoring with HWiNFO showed the core voltage finally stabilizing between 1.25V and 1.28V. I did hit a snag where the system hung at the splash screen during the first boot, but adding a tiny 0.01V bump to the DRAM voltage fixed it. VRM temps stayed chill at 52-58℃. After a full stress test, the stuttering is gone, though the BIOS menu is still a bit clunky to navigate.
