How to fix the Fanxiang S910PRO 2TB stuttering in Sword and Fairy 7?
The moment I hit a crowded town, the screen just freezes for a fraction of a second—it's an absolute nightmare at 4K. The Fanxiang S910PRO has a beastly cache, but with PCIe 5.0 bandwidth, the controller temp shot from 42℃ to 84℃ in under 30 seconds, triggering a hard thermal throttle. I tried capping the PCIe link to Gen4 in BIOS, which dropped temps to 60℃, but I lost nearly 40% of my read speeds, which felt like a total rip-off. Instead, I went into Advanced Power Settings and disabled Link State Power Management (LPM), then dropped the M.2 fan trigger threshold to 40℃ in BIOS. Watching HWiNFO, the read speeds stopped swinging wildly between 1200 MB/s and 6000 MB/s and finally settled at a rock-steady 10000 MB/s. I actually hit two random reboots while locking this down until I tweaked the motherboard voltage offset. Now it stays between 58-65℃. Ran a CrystalDiskMark stress test and the curve is finally flat. Parameters saved.
