Why does my high-end KingBank DDR5 cause stuttering in Splinter Cell Remake?

It's ironic that such high-frequency memory causes stuttering during stealth; the 6000MHz speed put too much pressure on the CPU memory controller. I tried increasing virtual memory, but this actually increased system response latency and made frame drops worse, which felt futile. I used the GamePP Resource Scheduler to set the game to Realtime priority and restricted background software memory usage. RTSS showed frame generation time converged to 12-16ms, and HWiNFO confirmed memory temperatures at 48-54℃ while BIOS locked it at 5800MHz.
