Can PCIe link speed fix texture loss on Colorful B450M-T M.2?
This was ridiculous—in such a beautiful game, I had characters walking around with transparent clothes. It felt like I was playing a game from ten years ago. I found that the PCIe link on my Colorful BATTLE-AX B450M-T M.2 was occasionally dropping from Gen3 to Gen2 under load, causing 4K random read speeds to plummet from 50MB/s to 12MB/s. I tried disabling Fast Startup in Windows, but that just made my boot times longer and did nothing for the textures, which felt like a total waste of time. I finally went into the BIOS, forced the PCIe speed to Gen3 instead of 'Auto', and updated to AMD Chipset Driver v5.12. Using a monitoring tool, I saw read latency drop from 120ms down to 45-55ms, and the texture gaps vanished. I had some slow boot issues after locking Gen3, but disabling CSM mode cleared that right up. Now the SSD stays between 45-52℃ and the southbridge is around 58-63℃. I exported the logs to confirm, and fans are steady at 1400-1600RPM.
