I'm getting memory overflow and stuttering in dense vegetation areas in Crysis with my Kingston 16GB RAM. Fix?

Sprinting through the jungle, I felt these micro-hitches every few seconds. In a firefight, that kind of lack of responsiveness is absolutely lethal. Resource Monitor showed my Kingston RAM usage hovering at 92-96%, with bandwidth utilization swinging by 15-20%. I tried lowering the vegetation density in the settings, which boosted the average FPS but didn't actually stop the hitches—a typical compromise that solved nothing. I went into the BIOS and manually tightened the primary timings from 19-19-19-43 down to 16-18-18-38, and bumped the virtual memory to 24GB. In CrystalDiskMark, the read speed jumped from 32GB/s to 38-41GB/s, and the hitches vanished. I actually pushed the voltage to 1.4V at first and the RAM got way too hot, so I backed it off to 1.35V. Now, RAM temps are 45-52℃ and the CPU is at 65-72℃. The game finally feels responsive again.
