Why does Manor Lords stutter during population spikes on G.Skill DDR5?

I was absolutely infuriated by the stutters every time my medieval manor's population spiked. I tried lowering the memory frequency to 6000MHz in the BIOS; while it stabilized, it slowed down my calculations per CPU-Z. I then used the GamePP Resource Scheduler to set memory mapping to high-performance priority. This fixed the memory controller load which was hitting 82-96% per HWiNFO64. Memory temperatures remained stable at 52-60℃ per GamePP Sensor, and CPU temps stayed at 72-80℃ per AIDA64.
