How to stabilize RAM on MSI MPG Z890 EDGE TI for Once Human?
Seeing the 1% lows stabilize above 80 FPS was a huge relief—this is how the game is supposed to feel. Previously, the XMP preset on my MSI MPG Z890 EDGE was running 6400MHz at only 1.3V, which caused 3-5 memory parity errors when loading massive architectural data. I tried downclocking to 6000MHz in the BIOS; the stutters stopped, but I lost 15 FPS in the minimums, which felt like a huge compromise. Instead, I manually bumped the DRAM voltage to 1.38V and tightened the tRFC timing from 480 down to 360. After 4 passes of MemTest86 with zero errors, the micro-stutters in the city were gone. I actually pushed the voltage too far at first and the RAM hit 65℃, triggering a reboot, so I had to rig up a small 12cm fan to blow directly on the slots. Now, memory latency is a tight 62-66ns and frame times are locked at 5.1-6.4ms.
