How to fix random FPS drops in Far Cry 6 with Asgard Bragi II DDR5?

While sneaking through the jungles of Yara, the frame rate would suddenly plummet from 90 to 30 FPS, accompanied by screen tearing. I first tried 'Extreme Performance' in the driver panel; while peak FPS rose, the frequency of drops actually increased, making me very cautious. I used the GamePP BIOS Load-Line Voltage Adjustment Wizard to increase voltage from 1.35V to 1.40V. 3DMark showed frame times stabilized at 12-16ms, while latency hit 115-135ns per AIDA64 and temps at 50-58℃ per HWInfo.
