I'm getting micro-stutters during high-speed combat in Scarlet Nexus with my Kingston 16GB DDR4 2666. How do I fix this lag?

During fast-paced dash attacks, the screen had this subtle 'twitching' sensation that was incredibly distracting, especially at 4K. AIDA64 revealed that while the Kingston 2666 RAM was stable, the low clock speed was causing the CPU to choke on particle effects, leading to scheduling delays of 18-25ms. I tried disabling every possible background service, but the frame variance stayed the same—software tweaks are a joke when you're hitting a hardware wall. I went into the BIOS and tightened the timings from 19-19-19-39 down to 16-18-18-36 and pushed the voltage to 1.35V. Real-time monitoring showed latency stabilizing between 82-88ns, and the combat fluidity improved drastically. I did have a couple of crashes when running heavy apps right after the change, so I had to loosen tRAS from 39 to 42 to get it rock solid. RAM temps are now 40-46℃ and fans are at 1200-1400 RPM. Frame times are now a consistent 5.1-6.4ms. It's a night and day difference.
