Why does my Samsung 9100 PRO stutter during fast travel?
When loading the massive England map, the screen would just freeze for a split second, which is honestly bizarre for this level of hardware. My Samsung 9100 PRO 4TB was running in PCIe 5.0 mode, but HWiNFO showed the link speed flipping between x4 and x2, causing the actual bandwidth to swing wildly from 6GB/s to 12GB/s. I first tried updating the motherboard BIOS to the latest version, which fixed some minor compatibility quirks, but the bandwidth jumping persisted—that's when I realized signal interference was the real culprit. I dove into the BIOS, forced the PCIe slot speed from Auto to Gen5, and disabled CPU PCIe Link Power Management. In AIDA64 storage benchmarks, sequential reads stabilized at 12.5-13.1GB/s, and those stutters completely vanished. One downside: locking Gen5 bumped the idle temp by about 5℃, so I had to slap on an active cooling fan to bring it back down to 45-50℃. Now, full-load temps sit at 62-68℃ with rock-steady performance. I verified the link stability via system bandwidth analysis, and frame times are now a consistent 5.1-6.4ms.
