Phantom Blade Zero is stuttering in complex scenes with my Kingston FURY DDR3 1866, can priority settings fix this?

Running a modern game on this memory is basically torture. My minimums were dropping to 15 FPS, making the game look like a slideshow—absolutely pathetic. The bandwidth on the Kingston FURY DDR3 1866 is just too narrow for today's asset streaming, leaving the CPU idling while waiting for data. I tried dropping the resolution to 720p, which helped the average FPS, but those brutal stutters were still there, which felt like a joke. I went into the BIOS and tightened the timings from 10-10-10 down to 9-9-9 and locked the system virtual memory to 16 GB. Monitoring via RTSS, the 1% lows climbed from 15 FPS to 28 FPS, and the stuttering frequency dropped significantly. I did hit two BSODs due to memory parity errors after tightening the timings, but bumping the memory voltage from 1.5 V to 1.55 V stabilized it. Memory temps are around 45-52℃. I exported the latency data to verify the gain, but let's be real, this hardware is barely hanging on.
