Why does Hollow Knight: Silksong drop frames during combat with Corsair Vengeance 6400MHz memory?

The complex particle effects during fast movement were causing some nasty screen tearing, especially during boss fights where memory usage was hovering between 85% - 91%. I tried dropping the resolution first, but that just made the game look like mud and didn't fix the drops. I realized the bottleneck was actually instant bandwidth fluctuations. I went back into the BIOS, forced the frequency to a hard 6400MHz, and manually pushed the voltage to 1.42V. Checking with ZenTimings, the latency stabilized around 60ns. Interestingly, my RGB lights started flickering when I first bumped the voltage, which was a weird glitch until I updated the motherboard's lighting firmware. With temps sitting at 50°C - 55°C, the frame time interval tightened from 16ms to 12ms. This kind of feel-based tuning made the high-load combat way less stressful, and the controls finally feel snappy. Locking the voltage is way better than letting the motherboard auto-schedule; it's just a cleaner visual experience.
