My Galax B760M D4 feels sluggish in the fog of Silent Hill 2, is my RAM running too slow?

I finally found the culprit! My RAM was stuck at the base 2133MHz frequency, which is basically a crime for this hardware. This bottleneck caused a 12-18ms instruction delay when the CPU handled occlusion culling, making the camera feel like it was moving through molasses. I tried the 'Ultimate Performance' power plan in Windows, but it only added 3 FPS—completely useless. I rebooted into the BIOS and loaded the XMP profile to hit 3200MHz. CPU-Z showed the jump immediately, and my minimums leaped from 42 FPS to 68 FPS. It was an instant adrenaline rush seeing it run so smoothly. I did have a scare where the PC wouldn't POST after enabling XMP, but a quick reseat of the sticks and cleaning the gold pins with an eraser fixed it. RAM is now 40-46℃ at 1.35V. In-game monitors show frame generation is perfectly flat at 5.1-6.4ms.
