My Kingston HyperX Savage is causing huge FPS drops during multiplayer fights in Granblue, how to fix?

There is nothing worse than that suffocating feeling when the screen just freezes the moment you trigger a massive ultimate attack. My single stick of Kingston HyperX Savage 8GB DDR4 2400 was getting absolutely crushed, with bandwidth utilization hitting 92-98%, causing frame times to swing wildly between 16ms and 45ms. I tried bumping the virtual memory to 16GB in Windows, but that was a waste of time; it didn't stop the stutters, it just made them feel more random. I went back into the BIOS, forced the frequency from 2133MHz up to 2400MHz, and nudged the voltage from 1.2V to 1.35V. Using RTSS, I saw the frame times finally settle into a clean 14-18ms range. I actually hit a Blue Screen of Death (BSOD) right after the frequency bump, but it stabilized once I loosened the timings from 16-16-16 to 17-18-18. Memory temps hovered between 42-48℃. The stuttering is gone, and the combat feels responsive again.
