Fixing PCIe link resets on MSI MPG Z890 EDGE TI WIFI
The screen would just go pitch black for about two seconds during fast travel, which is a total nightmare when you're trying to jump into a raid. I tracked the issue down to the MSI MPG Z890 EDGE TI WIFI's aggressive PCIe power saving, which was erroneously dropping the link from Gen 4 to Gen 1.1 during scene transitions. I wasted money on a high-end certified cable thinking it was a hardware fault, but the black screens kept happening, which was incredibly frustrating. I eventually went into the BIOS, forced the PCIe slot speed to Gen 4 instead of Auto, and disabled every single Link State Power Management option. Checking the Device Manager, the bus bandwidth stayed pegged above 16GB/s without those annoying momentary dips. Interestingly, my boot time actually slowed down by 3 seconds after locking the protocol, but that was fixed once I disabled Windows Fast Startup. My chipset temps are hovering between 48°C - 54°C with RAM stable at 6400MHz. After ten consecutive fast travel stress tests, the black screens are gone, and RAM temps are chilling at 52°C - 56°C.
