Should I change PCIe link mode for Fanxiang S790 in Days Gone?
Absolute torture. Having 4TB of space is great, but during heavy asset streaming, my frame rate was swinging wildly between 60 and 35 FPS. The controller on the Fanxiang S790 4TB was overheating while pre-loading 4K textures, causing the clock speed to dive from 2.1GHz to 800MHz, which left the game engine just waiting on the drive. I tried enabling 'High Performance' in the drivers, but that just made it hotter and triggered the throttling even faster—total facepalm moment. I went into the BIOS and locked the PCIe link mode to Gen 4 and slapped on a 3mm thermal pad to beef up the cooling. Monitoring with GPU-Z, the read/write speeds finally stabilized in the 5.2-5.8GB/s range, and the frame drops vanished. I actually messed up the thermal pad installation at first and accidentally pressed against a motherboard capacitor, which caused a boot failure, but I repositioned it and we're good. Temps are now 58-64℃. I've backed up these BIOS settings so I don't have to do this again.
