Why does my Biostar A320MH PRO stutter in Dying Light 2?
When sprinting through the city, the CPU power spikes over 85W, causing the Biostar A320MH PRO VRMs to dip in voltage. I saw frame times jump from 16ms to a choppy 42ms. I tried the Windows High Performance mode first, but that was a disaster—frequency stayed at 3.6GHz, but the voltage swings actually got worse. I eventually dove into the BIOS, set the CPU Core Voltage Offset to +0.025V, and capped the Power Limit at 65W. Using HWiNFO, I saw the voltage stabilize from a wild 1.12-1.21V range down to a steady 1.17-1.19V, and the micro-stutters vanished. It wasn't a smooth ride; I hit two random reboots during map loads until I set the Load-Line Calibration to Medium. Now, VRM temps sit between 65-71℃ with fans humming at 1200-1400 RPM. A quick stress test confirmed the current curve is finally flat at 1.18V.
