I'm seeing memory latency spikes causing stutters during fast movement in Returnal on a Galax B760M, do I need to calibrate?

During high-frequency dodging, I noticed my memory latency was swinging between 75-88ns. It wasn't crashing, but those timing fluctuations were causing these subtle micro-stutters. I tried enabling Game Mode in Windows and killing every background app, but the FPS just hovered around 55-62 without any real improvement. I eventually went into the BIOS, switched the memory controller to Manual, and locked the tCL to 16 for my 3200MHz kit. In the monitoring panel, latency snapped to a steady 72-76ns, and frame time variance dropped from 12.4-18.2ms to 8.5-10.1ms. I actually tried bumping the RAM voltage to stabilize the frequency first, but that just caused local overheating; after two reboots and rolling back the voltage, I realized timing sync was the actual fix. The RAM slots on this board don't have great cooling, but it's performing as expected now. AIDA64 stress tests passed, with RAM temps sitting between 42-48℃.
