Fixing storage scheduling on Galax B760M White Phantom?
It was honestly ridiculous; in these gorgeous jungle scenes, my character was walking around with transparent clothes. The PCIe link on the Galax B760M D4 Wi-Fi White Phantom was occasionally dropping from Gen4 to Gen3 under load, causing 4K random read speeds to tank from 55MB/s to 11MB/s. I tried disabling Fast Boot in Windows, but that just made my boot times longer without fixing a single texture, which was a complete waste of time. I went into the BIOS and forced the PCIe speed to Gen4 instead of 'Auto' and updated to Intel Chipset Driver v11.0. Using a monitoring tool, I saw read latency drop from 115ms to 42-52ms, and the texture gaps finally vanished. I had some slow boot issues after locking Gen4, but disabling CSM compatibility mode fixed it instantly. SSD temps are now 45℃ - 52℃ and the southbridge is at 58℃ - 63℃. I exported the read logs to verify, and the fans are humming along at 1400-1600RPM.
