My CPU clock drops and causes hitches when switching planets in Starfield on a Maxsun B850M, how do I stop this?

I hit some brutal instant frame drops whenever I entered a new city. My monitoring software showed the core voltage jumping wildly between 1.1V and 1.3V, which sent the clock speeds bouncing from 3.5GHz to 4.2GHz. I initially tried lowering the resolution to ease the load, but that just made the game look like mud while the stuttering persisted—a totally useless move. I decided to go deeper into the motherboard settings and set the VRM Load-Line Calibration offset to -20mV and switched the CPU power plan to Ultimate Performance. In the sensor panel, the voltage ripple shrunk from 0.15V to just 0.04V, and frame times stabilized from 18.2-25.4ms to a clean 11.5-13.2ms. I'll admit, my first attempt at aggressive overclocking just led to a loop of BSODs; it took four hard reboots and a careful recalibration of the voltage steps to find this sweet spot. The VRM temps still hover around 78-82℃ during peaks, but the fluidity is back. Comparing the frequency curves in OCCT, the CPU no longer triggers thermal throttling, and RAM stays between 58-63℃.
