Why does Cities Skylines II crash with memory mapping errors when loading huge city MODs on a Soyo SY-Yanlong B550M?

I spent hours building this city only for a MOD to crash the whole thing—honestly, I just wanted to scream. The Soyo SY-Yanlong B550M struggled with 64GB of RAM under full load; the SoC voltage was fluctuating between 1.0V - 1.1V, causing memory mapping table checksum errors and instant system crashes. I tried lowering the MOD resolution, but the city looked like a cardboard box and it still crashed—a total waste of time. I went into the BIOS and locked the SoC voltage at 1.15V, bumped DRAM voltage from 1.35V to 1.4V, and fixed the virtual memory page size to 4096MB. After 4 passes of MemTest86, errors dropped from 2 per hour to zero, and the crashes stopped. I did almost fry the board because the VRM hit 90℃ during the voltage tuning, but adding a small spot fan saved the day. RAM temps stayed around 45℃ - 52℃. I exported the optimized voltage profile using the board's backup tool, and the input response feels way more snappy now.
