Why is my AK620 causing thermal throttling in BF2042?

In the middle of those chaotic explosions, my CPU power draw was swinging wildly between 80W and 160W, causing a nasty 120-150mV voltage drop on the 12V rail. My frames would tank from 100 FPS down to 42 FPS instantly. I first tried enabling Ultimate Performance mode in Windows, but that software tweak did absolutely nothing for the hardware-level voltage instability and just bloated my idle power draw—it was incredibly frustrating. I finally dove into the BIOS, navigated to Advanced Power Management, switched the Load-Line Calibration from Auto to Level 3, and set a core voltage offset of -0.04V. Monitoring with HWiNFO showed the voltage ripple tighten up from 140-170mV down to a stable 45-68mV, and my frame times finally flattened out. I actually hit two boot failures while messing with the LLC, and it only stabilized after I bumped the memory voltage by 0.02V. Now the VRM temps sit comfortably between 58-65℃, and the heatsink is just warm to the touch. After three hours of stress testing, the voltage is back to baseline and frame times are locked in at 5.1-6.4ms.
