Just built a new system. The main nvme slot is working fine (t705 4tb is hitting advertised speeds on Crystal DiskMark).

The issue is the T500 2tb nvme ssd running on the PCIe Gen4 port.

The advertised seq read and write is 7400 MB/s and 7000 MB/s respectively. I am only getting 6500 MB/s and 6400 MB/s read and write speed on the SEQ1m/Q8T1 test on Crystal Disk Mark 5x 1GiB test.

Other hardware (unsure if it matters)
2x48gb team group ddr5 ram
9950x amd cpu
gpu 3080ti
os: windows 11 (up to date).
bios on motherboard is up to date.

Could I have a faulty nvme drive (just installed new today), or could the issue be the motherboard (or something else I'm missing).
