My Biostar H310MHD3 keeps dropping voltage during massive Dota 2 team fights, causing huge FPS dips. Why is this happening?

In the heat of a chaotic team fight, I noticed my CPU core voltage plummeting from 1.20V down to 1.12V, which sent my frame rate crashing from 80 FPS to a stuttery 35 FPS. It was a total nightmare. The VRM on the Biostar H310MHD3 just can't keep up with transient power spikes, causing the clock speeds to bounce wildly between 3.2 GHz and 2.8 GHz. I first tried enabling 'Ultimate Performance' in Windows, but that was a mistake—my CPU temps spiked to 90℃, triggering aggressive thermal throttling. After that disaster, I dove into the BIOS, navigated to Advanced Voltage Settings, and manually set the CPU Core Voltage Offset to +0.05V while cranking the chassis fans to 85%. Using AIDA64 for stress testing, I managed to keep the voltage ripple within +/- 0.02V, and my frame times finally tightened up from a messy 15-40ms to a steady 12-18ms. I did encounter some annoying coil whine after the first voltage bump, but that vanished once I switched the load-line control to medium mode. VRM temps stayed around 72-78℃, and the core hovered between 65-72℃. Everything is now saved in my BIOS profile.
