Solving PCIe link stability on Onda A520-VH-W?
It's honestly wild that this board can crash drivers in an older game, but here we are. The PCIe link on the Onda A520-VH-W was constantly flipping between Gen3 and Gen2 in Auto mode, causing sync errors during sudden load spikes that triggered a full driver reset. I tried rolling back to a three-year-old driver, but that was a total waste of time—it didn't stop the black screens and actually cost me 10 FPS. I finally went into the BIOS and forced the PCIe slot to Gen3, while simultaneously killing the PCIe Link State Power Management in Windows. After two hours of play, the black screens that used to hit every half hour completely vanished. I did notice the SSD read speed dipped by about 100MB/s after locking Gen3, but I couldn't care less compared to the crashing. Board temps are a steady 40-45℃ with fans at 1200RPM. Event Viewer now shows zero driver timeout errors, and fans are humming along at 1400-1600RPM.
