I'm seeing VFX stuttering in Starfield during heavy rendering. Is this a Kingston memory bandwidth bottleneck?

I mapped out the data flow for maxed-out settings: RAM read $ ightarrow$ cache transit $ ightarrow$ VRAM write. In the space station with all effects cranked, the Kingston dual-channel bandwidth hit a wall, causing throughput dips that made particle effects visibly hitch. I ran a stress test module to quantify the bandwidth utilization and watched the frequency stability tighten from 2468-2598MHz to 2513-2573MHz. My first benchmark was off by about ±7.3% from the expected value. I had to micro-adjust the memory timings and optimize the voltage curve before the baseline curve actually flattened out, bringing the frame-gen variance from 6.9-11.0ms down to 4.5-5.8ms. The memory controller power is still pulling 12.0-14.4W, and I can occasionally hear some coil whine in a dead-silent room. The cross-referenced rendering benchmark confirms the bottleneck is gone and the report is solid, though it took a few calibration passes to kill the initial heat spikes.
