NVME M.2 on Z170 Extreme 4 not working?

I did a full UEFI reset and tried it again, but still no luck. I also tried plugging the 1070 into PCIE port 4, but that didn't help either.

I appreciate all the effort and your honest words about a possible fix. Nonetheless, still a really annoying situation seeing as it's been keeping me busy for months now.

Not sure where I go from here, I'll probably have to go for another board (again) and/or check another GPU.


Would contacting the Asrock support make any sense in your opinion?

The 960 evo shows in the UEFI under storage (with the 1070 plugged in), but not in the system browser. I boot up Windows 10 and there is no Evo there. I reboot the PC, the Evo is gone from UEFI as well... I give up

Has the 960 EVO has been initialized and formatted in Windows 10 on another PC, or the Z270 PC? If it has not been initialized and formatted yet, it will not appear in Windows until is has been formatted.

If you open Windows Disk Management, are you prompted to initialize the 960 EVO? That should happen if it has not been formatted yet. From there is must be formatted, creating a new volume.

If you open Disk Management, you don't see the 960 EVO at all?

Or if you run a Windows Command Prompt (Admin), and run the diskpart command, and enter list disk, if the 960 EVO is formatted it should appear with a capacity of 465GB.

It if it listed, note the Disk #, and enter select disk n  where n is the numbers shown in the list for the 960 EVO.

If that works then enter detail disk, which will show the drive's name and other information.

I'm stuck about what the problem is. We have not had other reports of either of the boards you are using, having a problem with NVMe SSDs.
