I just bought my first Gen 4 NVME SSD NVME drive to use on my new workstation that I have built 3 weeks ago.
This video is a guide how to install it.
The main problem was simply getting the small screw into place with the massive heatsink.
I have not found any guide on this, but I used tweezers to get the screw in place, then I used the screw driver, and it worked very well.
Conflict with NVME Raid driver
I later had a problem with the NVME driver which I discuss in this blog.
