How to fix memory bandwidth issues on MSI A520M-A PRO?
Walking through those stunning landscapes was ruined by these random, jarring stutters that just killed the mood. My AIDA64 tests showed memory bandwidth at a pathetic 22-25 GB/s, which happened because I'd accidentally slotted my RAM in single-channel mode, creating a massive I/O bottleneck for the CPU. I tried adding more virtual memory first, but that did absolutely nothing for a hardware bandwidth bottleneck, and the stutters stayed exactly the same—a total waste of time. I shut everything down and moved the sticks to the second and fourth slots, then verified dual-channel was active in the BIOS. The bandwidth immediately jumped to 44-48 GB/s, and the scene transitions became incredibly fluid. I did have a moment of panic when the system didn't recognize one of the sticks after the move, but a quick clean of the gold pins with an eraser fixed it right up. Now, memory temps are sitting at 40-45℃ and the board is running great. Benchmarks confirm the data transfer rates are finally where they should be, with temps holding at 40-45℃.
