Freezes / noa ccess to NVMe SSD 970 Pro 1 TB



I have freezes / access issues with my SSD 970 Pro 1 TB. Before I got my 970 Pro I've never had such issues when using my SM961 only.





  • NVMe 9700 Pro 1 TB, last drivers installed, Firmware 1B2QEXP7, samsung magician all ok
  • NVMe SM961 128 Go

Other hardware:

  • Asus Strix Z270-I, last BIOS, two NVMe slots (A and B)
  • i7 6700k
  • 1080 Ti KFA2 EX OC
  • Corsair Vengence LPX DDR4 3000 MHz CL15
  • Corsair SF600

Power management settings should be ok

  • sleep: Never.
  • screen shutdown - Never.
  • AHCI link power management HIPM DIPM - Never
  • AHCI link power management adaptive - 0 ms
  • Shut down HDD after - Never

Windows fully updated, all drivers updated

No syslogs at the time of crash or before (checked many times)

Benchmark read 3468 Mo/s write 2698 Mo/s


What I have tried so far:


- Win10 / Linux dual boot on the SM961 (slot A), games stored on the 970 Pro (slot B)

- Win10 / Linux dual boot on the SM961 (slot A), 970 Pro as storage + games on it (slot B)

- Win10 / Linux dual boot on the 970 Pro, games on it

- I tried switching the slots

- I tried reseating the SSD, same issues


All lead to freezes at least at some point when gaming. Don't remember the configuration where I didn't have access to the ssd data anymore though


Please help, I don't know what to do anymore Smiley Sad.
