How to stop memory parity errors on Soyo SY-Yanlong B550M?
There is nothing worse than a perfectly timed jump being interrupted by a black screen and a full system reboot; it completely kills the immersion. Checking the logs, I found that the Soyo SY-Yanlong B550M was having a meltdown with 3200MHz RAM, where the tRFC timing was jumping between 580-640ns, triggering the error correction mechanism constantly. I tried the lazy route first by dropping the frequency to 2666MHz, which stopped the crashes but tanked my loading speeds by about 12%, which felt like a pathetic compromise. Instead, I kept it at 3200MHz but manually loosened tRAS from 38 to 42 and bumped the voltage from 1.35V to 1.38V. Under AIDA64 stress tests, the read latency stabilized at 72-76ns, and the crashes stopped entirely. I did hit a wall during my second timing tweak where the system just froze at the boot screen twice, and I had to bump tRC by 4 cycles to get back into Windows. Memory temps hovered between 40-46℃. I ran 6 full passes of MemTest86 and got zero errors, so it's finally reliable.
