Why does my system stall when switching maps in Armed to the Gears?

Navigating the floating city was painful because loading screens hung for over 4 seconds. I tried swapping memory slots, but it caused a brief system hang, which was even worse. I used the GamePP BIOS Load Line Voltage Adjustment Wizard to raise voltage from 1.35V to 1.40V and locked timings at 30-36-36-96. MemTest86 ran 6 loops with zero errors, and GamePP sensors confirmed stable 6000MHz frequency at 48-55°C, eliminating the lag.
