How to fix sluggish response in Expeditions Rome on DDR5?
My commands were lagging by about 150ms, and that 'mushy' feeling is a complete disaster when you're trying to micromanage a battlefield. Looking at the logs, the default 40-40-40-76 timings on the Corsair Vengeance 96GB kit were way too loose, causing the CPU to queue up data for all those units. I tried enabling Windows Game Mode and tweaking the power plan, but while the FPS went up, that input lag stayed exactly the same. It was a total mismatch. I went into the BIOS and forced the primary timings down to 36-36-36-68 while pushing the voltage to 1.38V. MemTest86 showed latency dropping from 105ns to a crisp 78-82ns. I did try pushing for 32-32-32-60, but the system just hard-locked at the boot screen. It took three restarts to realize 96GB just can't handle those aggressive numbers. Temps hovered around 55-61℃ with fans at 1200 RPM. After a four-hour stress test, the system is finally stable and the lag is gone.
