How to stop power delivery spikes on Soyo SY-A320D4+?
During heavy pushes, my CPU power draw spiked over 80W, causing the VRMs on this Soyo SY-A320D4+ to dip in voltage. This sent my frame times jumping from 18ms to a choppy 45ms. I tried enabling 'Ultimate Performance' in Windows, but that was a mistake—frequencies stayed at 3.6GHz, but the voltage swings actually got worse. I had to dive into the BIOS, set a positive CPU Core Voltage Offset of 0.02V, and hard-cap the Power Limit (PL1/PL2) at 65W. Using HWiNFO, I saw the voltage stabilize from a wild 1.10-1.22V range down to a tight 1.15-1.18V. The micro-stutters vanished. It wasn't a clean ride, though; I hit two random reboots during map loads until I switched the Load-Line Calibration (LLC) to Medium. VRM temps settled between 68-74℃ with fans humming at 1300-1500 RPM. After running a stress test, the current curve finally flattened out, and my frame times locked in at a rock-steady 5.1-6.4ms. My hands aren't shaking from lag anymore.
