Why is Ghostwire: Tokyo freezing during ability use?

While using abilities in Tokyo, the screen would occasionally freeze for a split second, which made me very anxious. I tried enabling the High Performance power plan in Windows, but it did nothing for DDR5 stability. I entered the GamePP BIOS Load-Line Voltage Adjustment Guide, raised the SOC voltage to 1.25V via HWiNFO, and optimized timings to 32-38-38-72. AIDA64 showed latency converged to 68-74ns, and Cinebench R23 stress tests confirmed stability at 52-58℃.
