Running into the same issue. Big disappointment with this NVME drive :-(

I have tried the latest MSI chipset driver for my MoBo first same result. I tried the AMD x570 chipset driver but the latest version (amd_software_2.03.12.0657) is stuck during setup. I used the previous version (amd_software_2.01.15.2138), but still not luck.
It seems right after login into win10 I can get 2200MB/s write and after a while it goes back to 500MB/s.
Super annonying.
