How to optimize storage bandwidth for ASUS Z890-A Snow in Minecraft?
The difference is insane—after the tweak, chunk loading that used to take 15 seconds now takes about 4! I found that my NVMe drive on the ASUS Z890-A Snow was running in PCIe 3.0 mode, capping my read speeds at 3500 MB/s, which caused massive hitches in RT mode. I tried updating the system drivers first, but that only saved me about 0.5 seconds, which was basically useless. I then flashed the latest motherboard firmware and went into the BIOS to force the PCIe slot from 'Auto' to 'Gen4'. CrystalDiskMark showed sequential reads jumping to 7200-7500 MB/s, and the game finally felt fluid. I did notice the SSD temp hit 75℃ initially, but adding an M.2 heatsink brought it down to 48-55℃. The VRM temps are sitting at 52-58℃. The system info panel confirms the protocol upgrade, and the core clock is stable at 2610 MHz.
