I don't think I read that anyone did this when trying the M.2 SSDs in the various M.2 slots, but did you clear the UEFI/BIOS after installing the M.2 SSD in the other M.2 slots?

To answer some questions in the first post in this thread, NVMe is a storage protocol of its own, and does not use the SATA controller built into mother boards. So setting the SATA mode to AHCI or RAID will have no affect on the detection of an NVMe SSD.

But since most Intel 200 series chipsets supports NVMe SSDs in RAID, that mode must be selected before a RAID array of NVMe SSDs can be created. The PCIe Remapping option for each M.2 slot being used with an NVMe SSD that will be part of a RAID array must be enabled.

As long as the M.2 slots are used for NVMe SSDs, the PCIe 3.0 lanes from the CPU will not be used. So a video card has no affect on the M.2 slots on an Intel Z170 or Z270 board.

Hi all, 

I'm here to say this issue is occurring with my Z270 Taichi as well, purchased from NewEgg on 1/31/2017.

I have a Toshiba THNSN5256GPU7 M2 NVMe fresh out of working Dell Precision 5510 laptop. The drive works fine in the laptop and on Z270 Taichi ONLY in the M2_2 slot.  But it's not detected by the BIOS in M2_1 or M2_3 (the ideal slot because of lane mappings).

I've tried UEFI 1.34 and UEFI 2.0.

I've tested with all my SATA drives unplugged and only this M2 NVMe drive installed.

There is another report on NewEgg of an identical issue, perhaps the OP here?  I updated my review on NewEgg to reflect my feature limited Z270 Taichi.

What's the deal here, is this a UEFI issue or hardware issue?

Update: tried to troubleshoot this with ASRock, but they were of no help. They issued an RMA, but the terrible RMA process requires me to disassemble my rig and leave it in pieces for 2 weeks while I ship them my broken motherboard and they ship me a supposedly working one.

Unfortunately, I parted out my old rig months ago when I built this (having not tested M2 slots yet) and now have no option for a alternative working computer which I use for 8-10 hours/day during the work week.  Never purchase ASRock products for machines you use every day and depend on.

I did reset the UEFI settings by loading the defaults and rebooting on UEFI 2.0 with no SATA devices plugged in.  Nothing.  Tried it twice.  Additionally, when upgrading from 1.34 to 2.0 it reset the UEFI settings as well.

An SSD holding you back is what you state the above holding you back???????????


Are you aware that there were some THNSN5256GPU7's that are tied to specific hardware? Probably not.


Why on earth did you wait "months' considering this is a computer you rely on 8-10hrs a day.

Why on earth is it you can't use for the time being a rotational HDD?

Go to the below page, scroll to H.OCZ (Toshiba) NVMe Drivers, download the "pure' version for your x86 or x64 Windows OS

I have no idea what you're saying here.

I am aware that the Toshiba drive is an OEM drive, tied to specific hardware though is not true.  It works fine on slot M2_2.

Because I didn't have an M2 NVMe drive available.  I assume ASRock built quality products and that the M2 slots would work when I bought M2 drives.  However, this was a bad assumption.

The harddrives aren't the problem.  The problem is that my entire computer will be non-functional for 2-3 weeks while my motherboard is shipped around the country.  Unless I buy a competitor's motherboard, in which case I would have a ceremonial sacrifice of the Z270 Taichi.  Doing daily work on my laptop isn't an option either.

Ideally ASRock would put a hold on my credit card for the value of the replacement mobo for 2-3 weeks while I receive the replacement and return my manufacturer defective motherboard I'd have no problems.  However, this doesn't seem to be an option.

I don't run windows, I use Linux and the the M2_2 slot works fine on Linux with my initial testing.

How would Windows drivers affect what UEFI sees?  Are the other slots not bootable and only accessible from the operating system?

Agreed on the "place a hold' on CC's for faster turn around. That would be nice but I think ASRock would need a banking location/partner in every country so that banks wouldn't do the usual and flat refuse a charge from an outside country.

"works fine on slot M2_2" is rather oxymoronic, considering, wouldn't you say? I do.

That the drive you have may be a tied drive, tied to specific hardware though is maybe true and it just happens to work in 2_2


I'd contact Toshiba/OCZ and inquire if indeed it is tied, BEFORE blaming the MB so damn fast.

Be prepared to quite possibly have the exact same issue with your RMA'd board with this drive.

While you impatiently wait, contact Toshiba/OCZ .

Sorry. Forgot.

F6 those drivers I linked and choose Toshiba(/OCZ?) XG3 Series.


Best I can think of, otherwise it is a tied drive.
