I'm using Corsair vengeance 16gb ram 3000. I tried it in single channel dual channel and with one stick of memory. I also turned xmp off and played with every bios option imaginable. I have exact same problem as the guy up top. |

" rel="nofollow - That does not sound good about the M2_1 and M2_3, there is no reason besides a problem with the board, apparently, that would cause that situation. If you check the System Browser feature in the Tools screen, you did not see the M.2 SSD(s) in the M2_1 and M2_3 slots? I have an ASRock Z170 Extreme7+ board that has three M.2 slots like your Z270 Taichi board does. I've had different M.2 SSDs in all the slots, including an OCZ RD400, and all the M.2 slots worked fine at the same time. I do not understand this from one of your post's above, "I even populated the second m.2 via an PC express adapter and it still wouldn't work in either of the m.2 slots". Did you mean you used an M.2 SSD in an M.2 to PCIe adapter card, in a PCIe slot, and the SSD was not recognized? When M.2 to PCIe slot adapter cards are used, the only place you'll see those drives is in the System Browser screen. It sounds like you've checked about everything you can to get the M.2 SSDs recognized. You should not need the latest or any particular UEFI/BIOS version for the M.2 SSDs to be recognized in a Z270 system. If you know both of your M.2 SSDs work in the M2_2 slot, but don't seem to work in the other M.2 slots, it sounds like your board is bad and should be replaced, sorry to say. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

" rel="nofollow - 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?

" rel="nofollow - 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. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

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? |

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?

" rel="nofollow - 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. |

" rel="nofollow - Your questions got me thinking and I pulled an EVO 960 out of the laptop that birthed the devil THNSN5256GPU7. Guess what, you're right, the EVO 960 works in all 3 slots. Now I can close all my RMAs and put away my pitchfork. I ran the OCZ Clout tool in Linux to see if there were any possible firmware updates, but I didn't see any. Looks like this drive will live in slot M2_2 and continue the coincidence of working.
Well, your response is little over the top. You have to understand my perspective: I'd seen the Toshiba drive work on TWO computers without issue and had seen nothing work in the ASRock motherboard. Initial google searches show a few threads and reviews with identical error reports and no resolution. Furthermore, the communications with ASRock included the model of the SSD and it didn't raise concern with them. I had little reason to suspect the THNSN5256GPU7. Suspecting the motherboard was the most rational initial response. It was, as stated above, wrong. Would be curious to learn more about this OEM locking you speak of. Does it have a formal name I can research?

That wasn't over the top, just MY perspective, from where I sit w/o having your hardware in front of me. I had my own repair shop with employees. I can't say I've seen it all yet I have seen an awful lot. hehe I know your perspective you found yourself in. It's a lonely, dark, place. Been there, done that. I'm just glad you didn't ship it off to RMA Land but instead found your answers here first. That would have been a major disappointment. All is fine there, that's what counts. Enjoy! hehe And please, consider ASRock on your next purchase  |

I won't be able to give this a try for a while, everything is buttoned back up, Toshiba drive in M2_2 and 960 Evo back in the laptop. I'll keep this in mind next time I tear in to them and follow-up. When I did test them, I didn't try any of the NVMe drives simultaneously (too lazy to find the spare M2 screws that are stashed away). I did try each NVMe drive in each M2 slot, one at a time with no SATA devices connected.

Have you reported this to OCZ/Toshiba? If other NVMe SSDs (960 EVO for example) work fine in all M.2 slots, but the RD400 doesn't then IMO that is more of an OCZ issue than an ASRock issue.

No, an NVMe SSD will disable two SATA ports on an Intel 100 or 200 series chipset board. Four DMI3 lanes from the chipset are used for PCIe x4 NMVe SSDs. A SATA M.2 SSD will only disable one SATA port (SATA3_3) when used in the M2_3 slot. But that is only for the M2_3 slot. Check the Storage section of the specifications: http://www.asrock.com/mb/Intel/Z270%20Taichi/index.asp#Specification" rel="nofollow - http://www.asrock.com/mb/Intel/Z270%20Taichi/index.asp#Specification If someone depends upon a PC for work or their livelihood and only has one PC, that is a big gamble. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

OCZ has been trying to figure out this issue with me but they dont have a z270 taichi motherboard for testing. THis is what he asked but I do not know the answer. "M.2 slots can be NVMe or AHCI. If they are using the AHCI protocol for SATA and not NVMe for PCI-e then no the RD400 will not work in that slot. It might fit in the slot, but it won?™t work. Is Asrock telling you that all 3 of the slots are NVMe over PCI-e?" |

Sounds like this will be a collection of people pointing fingers. We could look at this technically and try to hypothesize what's wrong since it seems clear that neither party is likely going to do it. It seems incredibly unlikely to me that my Toshibia OEM NVMe drive would be tied to a particular M2 port. Why would anyone do this? What's the upside to the manufacturers, they already devalue OEM drives by dumping the warranty, why make them more difficult for OEMs to implement? So, something is wrong with my OEM drive, the OEM drive could be labeled as a freak with special firmware. But shaun3883 has a retail Toshiba NVMe drive with the exact same problems. Perhaps with the same controller. There's another report by a different use on NewEgg with the same problems. Given that the NVMe drives are plugging in to the M2 slot with M edge key, we can narrow down the functions. Unless someone can produce some documentation regarding M.2 connector context being provided to the NVMe controller about what port it's plugged in to, I assume it doesn't exist because it doesn't make sense. That said we are left with a few things that could be causing issues: 1. PCIe lanes not working. It could be possible that the PCIe lanes aren't routed or something screwy. Perhaps the 960 EVO works in a x2 configuration behind the seems in the other ports and the Toshiba TC58NCP070GSB controller doesn't fallback and creates the failures we see. This would seem odd, but I didn't do any deep digging when I tested my 960 EVO in the other slots other then booting to the UEFI screen to see that it was present. Has anyone done performance tests comparing the same drive in 3 different slots? This could be telling. 2. The Z270 Taichi manual lists *no* Toshiba drives. Why is this? Is this a known issue by ASRock? Has anyone on used a Toshbia drive with the same controller on the problematic M.2 ports?  Perhaps it really is a problem with the Toshiba controller. If this was true, we should see this on other motherboards as well.

I installed the Samsung into my Asrock z270 taichi in the m-1 slot and it works fine. So apparently the oczrd400 can only work in the m-2 slot of this specific motherboard. It is a Toshiba problem. |

Do you have the Samsung Magician software installed? If you do it will tell you what the interface to the 960 EVO is. You should see PCIe 3.0 x4. I've seen 960 EVO users with other boards that only have a PCIe 3.0 x2 M.2 interface, and the Magician software correctly shows the interface is a PCIe 3.0 x2 connection. So you can easily verify the actual interface to your 960 EVO without running benchmarks. Why is a Toshiba OEM NVMe SSD not included in the Storage QVL? Simple, it's not a product sold at retail that is expected to be used in any mother board. I see its relative in the list above, the OCZ RVD400. You know that Toshiba owns OCZ now, right? Both the Toshiba and OCZ NVMe SSDs are the same hardware, that might have different firmware. The Storage QVL is not 100% inclusive of all NVMe SSDs that exist. The Samsung 960 Pro and EVO drives are not in the QVL of the paper manual, since I don't think they were available when the Z270 boards were initially released. Or ASRock simply did not have samples of those SSDs when the paper manual was printed. Actually, if you check the Storage QVL on the Z270 Taichi's web page, it now includes the 960 EVO. http://www.asrock.com/mb/Intel/Z270%20Taichi/index.asp#Storage" rel="nofollow - http://www.asrock.com/mb/Intel/Z270%20Taichi/index.asp#Storage Do we need a Storage QVL list for SATA SSDs or HDDs? No, since SATA is a standard protocol and any SATA drive should work in any board that provides SATA support. The same is true for NVMe SSDs. If any manufacture made a drive of any type that needed special support from a board, that would be a big mistake. Next, the M.2 slots on a Z270 board (or Z170, and the other 100 and 200 series Intel chipsets that provide this kind of M.2 support) do NOT use the CPU's PCIe lanes for the M.2 slots. The M.2 slots are connected to the DMI3 lanes in the Z270 chipset, as they are with the other chipset mentioned above. DMI3 is equivalent to PCIe 3.0, and is just Intel's terminology for these lanes within the chipsets. That is why using one of the M.2 slots causes two of the SATA III ports to no longer be available, and vice versa, they share the same resource, the DMI3 lanes. Do you have SATA drives connected to any of the SATA ports that are shared with the various M.2 slots? If you are using an M.2 to PCIe adapter card in one of these boards, then you will be using the PCIe 3.0 lanes from the CPU. I have an OCZ RD400 that I use in an ASRock Z270 Gaming K6 board, and have used it in both an M.2 slot and in its M.2 to PCIe adapter card, and it works fine. I've only used it in the M2_2 slot, since this board only has two M.2 slots. I am not aware of any known issue with that Toshiba OEM NVMe SSD, but since it is an OEM drive, how many people remove it from the PC it was sold with, and use it in another? My point is just the number of people that do that is very small. I'm sure it uses the same controller chip as the OCZ RD400. If your Toshiba NVMe, which is an OEM model and not sold at retail, has different firmware that for some reason causes an issue, who knows? Unfortunately, that Toshiba OEM NVMe SSD is not readily available since it is not a retail product. Why would it be included in any board's storage QVL list, if it is not sold at retail? Or be in the hands of many users of these mother boards? We don't know what is causing the Toshiba NVMe SSD to not be recognized in some of the M.2 slots. It's not always easy or possible to diagnose an issue without having the PC involved in front of us to experiment with. All we have to go on is what you are telling us. Was the Toshiba NVMe SSD the OS drive in the laptop? Or just a data drive? It may have special partitions on it that are common on drives included with PCs. Did you move it over as is, or completely reformat it before or after moving it to the Z270 Taichi? ------------- http://valid.x86.fr/48rujh" rel="nofollow">

If you are UEFI booting, the entry in the boot order for the OS drive will be Windows Boot Manager. You should also see the drive name in the entry, for example, "Windows Boot Manager: Samsung 960 Pro". Are you saying that in the Boot screen, you don't have an entry in the boot order that is Windows Boot Manager? Or if you do and select it, the PC will not boot? Otherwise, what do you mean by "native boot"? Did you have the CSM option configured in any way besides the default settings before you updated to 2.10? If you did, when you updated to 2.10, all the UEFI options were set to their defaults, and CSM was set to Enabled. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Hello, i know it is an old forum post but i have the same issue with an Asrock Fatal1ty Z270 i7 and a Corsair MP500 M.2 NVME SSD. It get only recognized in Slot M2_2. In M2_1 and M2_3 Slot the SSD get not recognized. It looks like, M2_2 is somehow different to M2_1 and M2_3. I think we have to life with that problem. What I find bad in this forum: Nobody from Asrock try to help. In forums from Asus and Gigabyte the employees are always active and try to find solutions. Best regards |
