How to fix memory instability on MSI A520M-A PRO for ZZZ?
Every time I loaded into a new area, the game would just freeze and crash to desktop without any warning. It was incredibly frustrating. On my MSI A520M-A PRO, the default memory profile was struggling with high-frequency data swaps, and the tRFC was bouncing between 600-650ns, causing the memory controller to spam error corrections. I tried updating the BIOS to the latest version first, but that actually made the crashes more frequent, which was a huge blow to my patience. I eventually gave up on XMP/auto-overclocking and manually dropped the RAM speed from 3200MHz to 2933MHz, while loosening the primary timings from 16-18-18-38 to 18-20-20-40. In stress tests, read latency climbed from 72ns to 78ns, but the crashes completely stopped. I actually messed up the voltage at first and let the sticks hit 60℃, but once I dialed it back to 1.35V, everything stabilized. RAM temps now sit at 42-48℃ and the CPU is around 60-65℃. After four hours of gaming, the input response feels way more consistent.
