How to fix memory parity errors in God of War Ragnarok?
Getting a black screen followed by a memory management error right in the middle of a boss fight is the absolute worst. The Crucial DDR5 4800MHz 16GB was struggling with complex physics data, with voltage fluctuating between 1.08V - 1.12V, causing the memory controller to truncate data under peak loads. I first tried downclocking the CPU to ease the IMC pressure; the crashes slowed down, but my FPS dropped from 85 to 62, which felt like a massive downgrade. I then went into the BIOS Advanced Voltage panel and forced the DRAM voltage to a steady 1.15V - 1.18V. After three full cycles of MemTest86, the errors (which were appearing twice an hour) completely vanished, and latency dropped from 88-94ns to a stable 82-86ns. I actually pushed it to 1.20V once and the system failed to boot, so I dialed it back to 1.15V. RAM temps sat at 45℃ - 51℃ with fans at 1100 - 1300 RPM. Everything is snappy now.
