My game keeps crashing during world map loads with G.Skill DDR5 6400, how do I fix this loading lag?

There is nothing more frustrating than a random crash to desktop right when you're building a massive base; it felt like gambling every time I clicked 'save'. Checking the logs, the default XMP profile on my G.Skill Trident Z5 6400 was hitting random latency spikes of 15-22 ns during heavy vertex data loads, causing the CPU to just give up. I tried flashing the latest BIOS, but that actually made the crashes happen more often—complete nonsense. I went back into the BIOS and manually loosened the primary timings from 32-39-39-76 to 34-40-40-80 and bumped the voltage from 1.35V to 1.40V. Running MemTest86 for six cycles took me from 48 errors down to zero. I actually messed up and set it to 1.5V once, which triggered an instant overheat restart and nearly gave me a heart attack. Temps stabilized between 52℃ - 58℃. After four hours of exploring the map, the compatibility issues are finally gone.
