Intel has made approximately zero effort to properly explain this to the public.
#WHAT IS THE STANDARD SATA AHCI CONTROLLER DRIVER FOR DRIVERS#
This prevents any non-Intel drivers from interacting with the NVMe drive when RAID is in use, but leads to the ridiculous situation that the SATA controller's mode affects PCIe SSDs. Samsung's NVMe driver, Intel added a feature to the chipset that when RAID is enabled, the NVMe device is remapped so that it can only be accessed through non-standard interfaces on the chipset's AHCI controller and the NVMe device cannot be accessed normally by any standard NVMe driver.

Intel took some shortcuts when implementing their NVMe RAID capability: rather than make a general-purpose software RAID layer for Windows that could work with eg.
On many systems, this manifests as NVMe drives in the M.2 slot not working properly with standard NVMe drivers when the storage controller is in RAID mode, but working fine when it's in AHCI mode. On Skylake and newer Intel systems, NVMe devices connected through the chipset rather than through the CPU's PCIe lanes can be affected by Intel's software RAID mechanism. The user has an M2 device he cannot get recognized as NVME because it is not an NVME drive but a SATA SSD attached to the M2 port. Windows 10: Using an NVME SSD in AHCI vs RAID mode The article in TenForums you report above has the title It cannot be both but the port does support both. What you must look for in these device descriptions is whether an M2 item is SATA or NVME.
Now just about all M2 devices are NVME, i.e., connect to PCIe lanes. But AFAIK only early M2 devices went that way, e.g., that 850 EVO mentioned in the Storage Review article.

While usuallyused to support an NVME device, like the 950 PRO described in the first sentence of the OP, the M2 will also support a SATA drive on a SATA port. A function of NVME is to bypass SATA ineffecienties and join the SSD to a PCIe port and thus provide for much faster ssd throughput.Ī confusion in nomeclature arises from the flexibility of the M2 port.

As noted I am currently booting from a Samsung 950 Pro NVME to Windows 10 圆4 and once I found all this information the actual setup time was actually really fast.Ĭlick to expand.Even if you could, it would not make much sense to run an NVME unit on the AHCI driver. The booting functionality I believe is in the chipset and BIOS so the Sandy Bridge versions should not make a difference. My specific rig has dual E5-2643V2 processors. That would be something to consider in setting up the configuration.įinally I am not sure about the Z220, Z420 models but the Z620 and Z820 share similar BIOS functionality and should be just fine.
#WHAT IS THE STANDARD SATA AHCI CONTROLLER DRIVER FOR INSTALL#
I am not sure if the NVME driver is pushed to Windows 7/8 or not but I would imagine a Windows 7 install would require the NVME driver before it would fully boot. I have seen posts claiming thier machine needed it pre-installed others did not. Windows 10 has an NVME driver native that was good enough to boot without custom OS installs for the 950 pro. In addition to the BIOS the OS must have the drivers installed to boot properly. The secure boot options are a possible pain point since they can toggle legacy support so be aware of those features. The BIOS is incredibly simple so not many options can be changed. I had to change around some settings to get the drive to boot properly.
I did not try any previous BIOS revisions so it is possible an older one works but I cannot speak to any other revision and recommend updated to the latest. My BIOS is revision 3.88 and the revision must be one of the newer versions although I am not sure exactly what BIOS revision added this feature. Second, the drive must be formatted GPT and configured for UEFI boot.īIOS revision should support UEFI version 2.3.1. Samsung SM951 (NVMe version) - NOT Bootable on zx20 machines I do not think Intel still sells the 750 series new either so the 950 pro was the only option I perceive to be currently viable if you are interested in purchasing a new drive to boot NVME. Here are the models with the BIOS OPROMS that should boot, I know the 950 pro works and others have had success with Intel's 750 series as they have legacy OPROMS as well.
