Stutters mid-fight, sharp dips when you turn the camera, a jerky picture in an open world — all of that can be caused not by the GPU or CPU, but by incorrectly configured system memory. RAM overclocking lets you get a real FPS gain without buying new parts, essentially for free, if you spend an hour or two on setup. One warning: overclocking requires careful voltages and mandatory stability testing. When you follow the rules, the procedure is fully safe for the hardware.
