U.2 to M.2

I use a Gigabyte U.2 to M.2 adapter with an Intel 750 on my Z170 Extreme7+ board, and it works fine. This adapter was provided free with the U.2 750, so must be universal. I also doubt that these adapters are are board specific, unless Asus did something to theirs.

When you say the 750's are not recognized, do you mean in the UEFI, Storage Configuration screen?

If so, then yes you won't see NVMe drives appear in a configuration screen for SATA drives, or the few PCIe SSDs that use an AHCI controller, like the AHCI SM951.

Did you check in the UEFI, Tools, System Browser, for your 750's? My Intel 750 and Samsung 950 Pro are shown in System Browser, the 750 using the Gigabyte U.2 to M.2 adapter.




My board's UEFI in the Advanced screen, has an NVMe Configuration screen. All this screen really does is list the NVMe devices, nothing else can be done.

Are you aware of the resource sharing of the M.2 slots and the SATA ports on all Z170 boards?

Are you saying you don't see the 750's in Windows?

I assume you are using RAID mode in the UEFI now? Do you see the RST PCIe Remapping options in the Storage Configuration screen? If so, are they Enabled? These options are required to be Enabled before you can create a RAID array of PCIe NVMe SSDs. You must save and exit the UEFI, and go back into the UEFI for those options to be applied.

Have you done anything with the CSM option in the Boot screen? That is another essential option that must be configured in order to use even a single NVMe SSD as an OS drive.

Important FYIs for you about PCIe NVMe SSDs in RAID arrays:

If you clear the UEFI/BIOS, the RAID array will FAIL on the next start of the PC, even if you immediately go into the UEFI.

If you update to a different UEFI/BIOS version, which also clears the UEFI, the RAID array will FAIL just as it does as described above.

The only work around for this: Remove/disconnect the SSDs in the RAID array before you start the PC after a UEFI clear or update. Reconfigure ALL the required options as described above. Save and Exit the UEFI, go back in the UEFI to check all is well, then shutoff the PC by holding down the power button. Then reconnect the SSDs again, and start the PC.

This is caused apparently by limitations of the Intel IRST driver. While it is annoying, Intel has at least provided us with the ability to create RAID arrays from PCIe NVMe SSDs, while supporting two different storage protocols (NVMe and SATA) on one platform at the same time. Yes that is a big deal. The PCIe RAID arrays are more fragile than SATA RAID arrays at this point.

Doesnt even see the drive in windows.

Yes, I have the power connectors connected. Is this the same parsec from the patriot forum days? This is bill gates.
