How to fix unstable frame rates in Ghostwire: Tokyo on Kingston 4GB RAM?

Facing ghost crowds in Tokyo, my frame rate fluctuated like an ECG, which was a total disaster for fluidity. I tried increasing virtual memory to 16GB via System Info, but the system just blue-screened after ten minutes, which felt like a cruel joke. I then used the GamePP BIOS Load-Line Voltage Adjustment Wizard to set LL to L2 mode and VDD to 1.35V. AIDA64 confirmed memory latency converged to 72-78ns, and HWiNFO showed memory temperatures remained at 48-55℃, making it smooth.
