How to fix storage link instability on ASRock B450M-HDV?
It's honestly wild that an entry-level board like this can just nuke the drivers in Nioh 2. The storage link on the ASRock B450M-HDV R4.0 was jumping between Gen3 and Gen2 during high-frequency data exchanges, causing a sync error that triggered a full driver reset. I tried lowering every single graphics setting to the absolute minimum, but it still crashed, proving this wasn't a GPU issue but a low-level link conflict. I went into the BIOS, forced the M.2 slot to Gen3, and disabled 'PCI Express Link State Power Management' in the Windows power plan. After two hours of gameplay, the black screens—which used to happen every 30 minutes—completely stopped. I lost about 300 MB/s in sequential read speeds, but for a system that doesn't crash, I'll take that hit any day. Motherboard temps are stable at 40-45℃ and Event Viewer shows zero driver timeout errors. Fans are steady at 1200-1300 RPM.
