How to stop Asgard Thor DDR5 6400 from stuttering in F1 25?
Hitting a corner at 300km/h and getting a micro-stutter is the worst. RTSS showed my frame times swinging wildly between 12ms and 35ms, which is just unacceptable for a racing sim. The default timings on the Asgard Thor DDR5 6400 were clearly bottlenecking the high-frequency physics calculations. I tried dropping the resolution from 4K to 2K, but that was a joke—the FPS went up, but the jitter actually got worse. I ended up going deep into the BIOS, crushing tRFC down to 380 and pushing tREFI up to 65535 to cut down on refresh cycles. Suddenly, the frame times converged into a tight 13-16ms window, and that buttery smooth feeling finally came back. I did have a couple of scary BSODs when I first tried to tighten the timings, but bumping the voltage from 1.35V to 1.42V stabilized everything. Memory temps sat between 55-61℃ with fans screaming at 1800 RPM. The frame time analyzer confirms the jitter is gone, and the steering response feels snappy now.
