How to fix Kioxia EXCERIA PLUS G4 1TB interface instability?
Distant buildings looked like a mess of pixels, slowly popping into focus—a total nightmare during stealth segments. After digging into the logs, I realized the Kioxia EXCERIA PLUS G4 1TB's auto-power saving was glitching, dropping the link state from 5.0 to 3.0 during high-frequency random reads. I wasted time slapping on a beefier M.2 heatsink, which did absolutely nothing for the latency, proving this was a protocol issue, not a thermal one. I went into the BIOS, forced the PCIe speed to Gen 5, and disabled all Link State Power Management options. In Device Manager, the bus bandwidth finally locked in above 12GB/s without those annoying dips. Weirdly, the first time I locked the protocol, my boot time increased by 2 seconds until I disabled Fast Boot. Drive temps are sitting at 50-58℃, feeling warm but stable. After ten consecutive map load stress tests, the texture pop-in is gone, and bandwidth is rock steady at 11.5-12.2GB/s. Fix confirmed.
