There seems to be some confusion regarding this drive. The SM951 is an AHCI drive NOT an NVMe drive.

  1. Samsung Xp 941 512gb Ahci M.2 Pcie Ssd Adapter For Mac Pro

It's a M.2 PCIe drive that runs in sata mode. It's connected via an M.2 PCIe x4 adapter card. This is not an NVMe drive, nor is it a raid drive and I am not attempting to configure it as a RAID.

It's read/write specs are 900/600, not those of an NVMe drive. There are 2 PCIe slots on the motherboard.

PCIe 1 ix x1. PCIe 2 is X16. PCIe3 & 4 are x1, and the last one PCIe 4 is x8. The adapter card is x4 (Obviously - no M.2 drive currently runs at more than x4). I can't pug the adapter in x16 if I want the graphics card in x16. That leaves only one choice. Which is fine.

Since it's not an NVMe drive, and since it's only running at x4. But for the sake of testing, I swapped the graphics and AHCI M.2 drive around and the results are identical. BIOS and Windows do not see the drive, recovery discs like Macrium and EaseUS and others all see the drive. It is an NVME drive, and I dont know where you got those stats from You need to do a little more research I think as you are mixing quite a lot up there. You seem to be quite misguided about certain things.

AHCI has nothing to do with NVME. All NVME drives will run in AHCI mode and most will run in RAID (the alternative to AHCI). I am not at all confused as its all very simple in all honesty. Your board has these expansion slots. 1 x PCI Express x16 slot, running at x16 (PCIEX16).

For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot. 1 x PCI Express x16 slot, running at x8 (PCIEX8). The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot will operate at up to x8 mode. 3 x PCI Express x1 slots (All PCI Express slots conform to PCI Express 2.0 standard.) 2 x PCI slots As you can see, only two are capable of running the drive. The adapter you are using on a legacy chipset will almost certainly rule out the possibility of using it as a boot drive as the drivers will be loaded only after the OS boots via PCIE.

I am not wholly clear on what you are trying to achieve. Hopefully someone can help you with your problem as you seem very frustrated by it. It is an NVME drive, This is NOT an NVMe drive!!!! I bought it before the NVMe version was even released!!!! Essential details The SM951 is the follow-up to Samsung's XP941, an older M.2 gumstick with a quad-lane PCIe Gen2 interface. This new generation cranks the same number of lanes up to Gen3 speeds, effectively doubling the aggregate bandwidth to 4GB/s.

To put that figure into perspective, consider that the dual-lane Gen2 interface behind the M.2 slots on most motherboards is limited to a mere 1GB/s. Only a handful of X99 and Z97 boards have 'Ultra,' 'Turbo,' or otherwise amped-up M.2 slots with enough bandwidth to fully exploit the SM951. Quad-lane slots should be more common on next-gen Skylake boards due later this summer. In the meantime, the SM951 can be mounted on an M.2 adapter card and plugged into any full-sized PCIe slot. There are actually two versions of the drive.

The initial release uses the familiar AHCI protocol, while a newer variant adheres to the NVM Express standard. Our focus today is on the AHCI model, which is compatible with a broader range of motherboards.

And I don't know where you got those stats from I did mean to type 1900/600. That was a typo, but in any case, you are right. The maximum is actually 2050, though I never got anything better than 1900 from the drive. Hopefully someone can help you with your problem as you seem very frustrated by it. I was hoping so too. What I'm frustrated by is the fact that I keep getting told I have a NMVe drive, when I know for a fact it's an AHCI protocol version. Now, that should be enough evidence to prove I have an AHCI version.

Not an NVMe version. What reviews say is that it is compatible with M.2 Adapter cards. The caveat is that support was only available from Z97 chipsets. If I hadn't been so adamant on proving I have an AHCI version I probably would never have come across that statement. So, I'll have to use my 750 EVO as the boot drive (And that answers your question of what I am trying to achieve. Install a SSD Boot drive).

In any case, I thank you for taking the time to at least try and help me out. We both learned something.
