How to fix memory checksum errors on ASRock Z370M Pro4?

There is nothing more frustrating than a total black screen and a hard reboot right when you're exploring the snowy peaks. The default XMP profile on the ASRock Z370M Pro4 just couldn't handle the massive datasets in this game, with memory latency jumping erratically from 85ns to 110ns, triggering fatal checksum errors. My first instinct was to downclock the RAM to 2400MHz; while the crashes stopped, my 1% lows tanked from 60 FPS to 42 FPS, which felt like a miserable compromise. I went back into the Advanced Memory settings and loosened the primary timings from 16-18-18-36 to 18-20-20-38, while bumping the DRAM voltage from 1.35V to 1.38V. This stabilized the latency at 72-78ns, and I managed 5 hours of gameplay without a single hiccup. I actually tried to push the timings too tight initially and got three BSODs in a row until I relaxed tRAS to 40. Now the sticks stay between 42℃ - 48℃. MemTest86 confirmed zero errors after 4 passes, and the system feels snappy again.
