Zephyrus S17 SSDs running at Gen3 instead of Gen4

[bzhang]

System: Laptop
Battery or AC: AC
Model: ROS Zephyrus S17 GX703HS (2021)
Frequency of occurrence: When an NVME SSD is installed outside a specific slot
Reset OS: Yes
Screenshot or video:

========================
Detailed description:
When running multiple NVME drives (or running just 1 or 2, but not in the correct slot), the drives only run at Gen3 speeds, as shown in the screenshot. Benchmarks also show the drives running slower than expected, both in RAID 0 and independently. Why is this?

Confirmed by the technical department, we use the same laptop as yours to connect three PCIE Gen4 SSDs. In RAID 0, using CrystalDiskMark to measure the read and write speed of SSD as follows: Read 7000 MB/s ; Write 6600MB/s. Can you install CrystalDiskMark to check if your read and write speed is slowing down? Sorry for any inconvenience it may be caused.
