How to solve Crucial DDR5 4800MHz stability in Horizon?
During intense fights with Thunderbirds, I noticed these tiny, split-second pauses. They aren't constant, but they absolutely kill the game feel. The auto-frequency scaling on the Crucial DDR5 4800 was causing the clock to jitter between 4733MHz and 4800MHz, leading to 5-10ms anomalies in frame generation. I tried updating the motherboard drivers first, but that did absolutely nothing. I eventually went into the BIOS and forced the memory frequency to a hard 4800MHz and manually tuned the tRCD from 40 down to 38. Looking at the RivaTuner frame time graph, the jagged spikes were smoothed out, and the frame intervals stabilized at 13-15ms. I had a couple of cold-boot delays after locking the frequency, but bumping the voltage slightly to 1.12V fixed that. RAM temps are sitting at 40-46℃, and the system is dead silent. Ran a 3DMark stress test for an hour with zero crashes, so it's officially verified.
