Should I lower RAM speed for MSI Z890 EDGE in Civ 7?
In the late game with massive maps, turn calculations slowed from 5 seconds to 15 seconds. It's a total mood killer for a strategy game. The default XMP profile on the MSI Z890 EDGE was hitting rare parity errors when handling huge amounts of unit logic, forcing the memory controller to constantly retry. I tried clearing temp caches, but it only saved me 1 second—I knew I needed a real fix. I went into BIOS and dropped the RAM frequency from 7200MHz down to 6000MHz, tuning timings to 30-34-34-80. Resource Monitor showed throughput stabilized at 52 - 56GB/s instead of erratic spikes, and turns started snapping back to normal. I didn't notice it immediately, but after three turns, the speedup was obvious. RAM temps are 45 - 51℃ at 1.35V. Four passes of MemTest86 showed zero errors. Hardware verified.
