Fixing AMD Ryzen 7 9700X memory latency in Titanfall 3?
Sliding across walls at high speed should be smooth, but my screen was twitching twice a second—it felt like I was playing a slideshow. The FCLK on my Ryzen 7 9700X was bouncing between 2000-2133MHz in auto mode, causing memory latency to swing from 68-82ns. I tried just enabling the EXPO profile, but the system wouldn't even POST, which is just typical hardware frustration. I ended up manually locking the FCLK at 2100MHz and bumping the DRAM voltage from 1.35V to 1.4V to crush those timings. AIDA64 showed latency finally settling at 62-65ns, and the micro-stutters vanished. I tried pushing it to 2200MHz once, but the game crashed after five minutes, so I backed it off. CPU temps are around 65-72℃ and RAM is at 50-55℃. I exported the latency distribution logs, and the bus calibration is finally dialed in.
