   Hi, 

I'm getting an BSOD - WHEA_UNCORRECTABLE_ERROR when using an NVME ssd 

My HW is: 
Z490M-ITX/ac (latest bios available )
Intel 10600 (non K)
2x 8GB HyperX Kingston 2400
Samsung 970 Evo Plus 500GB (latest firmware available )
Sabrent Rocket 4.0 500GB (latest firmware available )
PSU TT Smart M550w
No dGPU

Steps to narrow down the problem:
Ram1 -> slot1 or slot2 - fail
Ram2 -> slot1 or slot2 - fail
Samsung 970 m.2 slot1 or slot2 - fail 
Sabrent Rocket m.2 slot1 or slot2  - fail 
HDD 1TB SATA - everything works fine (so slow :) )
Bios Defaults - fail 
Setting PCI to GEN 3 instead of Auto - fail 
Unplug everything even keyboard - fail 

Checked thermals and they are around 30-40
The error only shows when using m.2 NVME 
Memtest from live USB - NO errors

Can anyone help to debug this further?
