Fixing RAM instability on MSI A520M-A PRO for Relink
Seeing those random micro-stutters during multiplayer raids was a total nightmare, especially when you're trying to time a perfect dodge. The MSI A520M-A PRO has a pretty basic memory trace layout, and with 3200 MHz XMP enabled, the memory controller was hitting 85-110ns of latency during heavy data swaps. I first tried downclocking to 2933 MHz, but I lost about 12 FPS, which felt like a huge step backward. Instead, I manually loosened the primary timings from 16-18-18-38 to 18-20-20-40 and bumped the DRAM voltage from 1.35V to 1.38V. In AIDA64, the latency jitter dropped from 12-35ns to a tight 8-15ns, and the stutters vanished. I actually blue-screened three times trying to tighten the timings too much before I realized I had to bump tRAS to 42 to get it to post. RAM temps are now 42-48℃ and the motherboard is at 50-55℃. After a full MemTest86 sweep, everything is stable, and the input response finally feels instinctive again.
