How to fix memory timing jitter on Crucial DDR4 3200MHz 16GB?

While fighting Teostra, the screen would just freeze for about 0.5 seconds during those massive explosion effects, which is a nightmare on a 16GB setup. I noticed the default voltage for my Crucial DDR4 3200MHz was bouncing wildly between 1.2V and 1.35V, causing the memory controller to hit latency spikes of 85-110ns when handling particle data. I tried switching to the High Performance power plan in Windows, but that was useless; the CPU stayed clocked up, but the RAM latency kept jumping. I eventually dove into the BIOS, manually locked the DRAM voltage at 1.36V, and changed the tRFC from Auto to 350 cycles. Checking RTSS, the jagged frame time graph finally flattened out into a smooth 12-16ms range. I actually tried pushing the timings to 14-14-14 at first, but the system just blue-screened during the map load. I had to loosen them to 16-18-18 to get it stable. RAM temps sat around 42-48℃, and AIDA64 confirmed a steady read speed of 44GB/s with frame generation times locked at 5.1-6.4ms.
