Why is my Crucial DDR5 4800MHz stuttering in Ratchet & Clank?
During those rift jumps, the system has to unpack and remap a massive amount of asset data instantly, which caused my memory load to swing wildly between 8.2 GB and 14.5 GB, tanking my FPS from 90 down to a choppy 35. I initially tried switching my Windows power plan to Ultimate Performance, but that software tweak did absolutely nothing for the hardware-level timing latency—it just bumped up my idle power draw, which was incredibly frustrating. I eventually dove into the BIOS, navigated to Advanced Memory Settings, and nudged the memory voltage from the default 1.1V up to 1.15V, while manually setting the tRFC parameter to 560 cycles instead of Auto. Monitoring with HWiNFO showed the memory latency tighten up from a loose 85-110ns to a crisp 68-75ns, making the jumps feel buttery smooth. I actually hit two memory parity errors on my first tRFC attempt, and it only stabilized after I pushed the voltage another 0.01V. Memory temps sat around 42-48℃ with the VRM feeling warm. After three hours of stress testing, the frame times finally leveled out at 5.1-6.4ms, though the BIOS menu is still a pain to navigate.
