How to fix I/O blocking on Fanxiang S910Max 2TB PCIe 5.0?
Whenever I fast-travel across the open world, the screen just freezes for about 150ms, which is an absolute nightmare during high-stakes combat. I noticed the Fanxiang S910Max 2TB's PCIe 5.0 link had response latency swinging between 12-24ns when handling fragmented assets. At first, I tried toggling 'Ultimate Performance' mode in Windows, but it did nothing for the stutters and just pushed my idle temps up to 52-56℃, which left me feeling completely clueless. I eventually dove into the BIOS, switched the NVMe Power Management from 'Auto' to 'Disabled', and forced the PCIe link speed to Gen5. Using HWiNFO, I saw random read latency shrink from 18-22ms down to a rock steady 6-9ms. The loading is night and day now. I did hit a snag where the system had a slight boot delay after disabling power management, but updating the latest chipset drivers killed that issue. Full load temps now sit around 68-74℃, and the heatsink is warm to the touch. Benchmarks show a flat transfer curve, so the config is finally locked in.
