How to fix low RAM frequency bottlenecks in F1 25 on Kingston DDR4?
At 300km/h, I was getting these tiny micro-jumps in the image, which is a death sentence in a competitive sim. The Kingston DDR4 2666 had a massive latency of 92ns, leaving the CPU idling while waiting for physics collision data. I tried increasing the page file size in Windows, but that did absolutely nothing for raw latency. I eventually went into the BIOS and bumped the frequency from 2666MHz to 2933MHz, while tightening the primary timings from 19-19-19 to 18-18-18. AIDA64 confirmed the latency dropped to 82-86ns, and the frame variance shrank from a 10-frame swing to just 2-4 frames. I tried pushing for 3200MHz, but the game crashed instantly until I bumped the voltage from 1.2V to 1.3V. RAM temps are fine at 42-48℃. The in-game frame-time analyzer confirms the jitters are gone, and the frequency version is now verified.
