Hopefully cloning your 840 to the SM951 NVMe will work getting the Win 10 NVMe driver working with the SM951. You'll be one of the first doing that experiment... Thumbs Up

Otherwise, since your 840 Win 10 installation is probably not a UEFI booting Windows installation, with the SM951 formatted in GPT, try this:

In the UEFI, Boot Order screen, scroll down to find the CSM option. Click on that and find the Launch Storage OpROM Policy option. Set that to UEFI Only. Then click Save and Exit in the Exit screen.

On the restart, go right back into the UEFI, and check the Boot screen. If you then see an entry for the SM951 with the prefix "UEFI:", select that as the first boot device. You may instead find the entry, "Windows Boot Manager". If you do, select that as the first boot device. Then save and exit, and see if you boot into Win 10 with your SM951 NVMe.

If that does not work, remember what you did see in the UEFI about the SM951, and we'll take it from there.

Hi I am a newbie on the site
I have just recieved a SM951 NVMe 256Gb and cannot get it to boot on my Z97 Extreme6
Pre ordered it after excellent review at http://www.tweaktown.com/reviews/7181/samsung-sm951-nvme-2-pcie-256gb-ssd-review/index3.html

I have latest BIOS 2.3 installed - I have set fourcing of M.2 but the BIOS says there is nothing in the slot
Windows 10 sees the card and I have used Paragon Hard Disk Manager 15 to clone my old Sansung 840 onto the SM951

Am I missing a setting so that the card shows and I can select it in BIOS as a boot device

I have sent technical support an email and then found this forum
Any help would be much appreciated

Ian

Including the SM951 NVME model installed to PCIE slot? What configurations can I use for the Radeon 285 and SM951 to both be in PCIE 3.0 slots?

An R9 285 will not max out the bandwidth of a PCIE 3.0 x8 slot so even if you end up with only 8 lanes you will not see any performance hit. In fact, the R9 285 shouldn't noticeably bottleneck at x4.

Having a hard time finding the SM951 NVMe model but definitely holding out till its pointless. Does the Z97M OC Formula have enough PCIe 3.0 for above stated and a PowerColor Radeon R9 285 2GB TurboDuo Video Card to operate at max potentials?

Thanks for the quick answer - that's simple and easy enough, I definitely appreciate it.

Since this thread is kind of about the SM951, I thought I'd share the fairly in depth review I saw of that particular SSD. So far it looks pretty nice - http://techreport.com/review/28446/samsung-sm951-pcie-ssd-reviewed

Cheer!

At most you will need to update to the latest bios to support booting from the SM951.

This appears to be as good a place as any to ask about the SM951. I'm planning on doing a nice clean sweep install for Windows 10 (Win 7 then upgrade). The SSD I'm looking at is (http://www.amazon.com/Samsung-SM951-256GB-AHCI-MZHPV256HDGL-00000/dp/B00VELD92U). I have an ASRock X99 Extreme 4. I would have purchased it last year sometime around Christmas. My understanding is that since that particular SM951 is an AHCI board I won't need to do anything special, right?

I saw someone mention that the new M.2s aren't precisely plug and play, but it seems like it should be fine as an OS drive with no extra effort. Would that be correct?

Any help would be greatly appreciated.

NVMe SSDs do not support AHCI AFAIK.

The AHCI and NVMe versions of the SM951 have slightly different model numbers. Both are enthusiast level products that are not plug and play devices (when used as OS drives), and not meant for those that don't understand what they are all about.

The same can be said for M.2, which really only has two versions, SATA and PCIe. IMO that is not a "minefield", but requires more attention than just grabbing an M.2 SSD off a shelf. Wink

Several reasons for that, the main one being the SSD's internal controller must be capable of using the NVMe protocol, which is more than simply driver/software support. The architecture of the SSD controller and the support chips for the controller (memory buffer) must be designed to work with NVMe.

NVMe is a major change in non-volatile storage IO. AHCI was designed to work with the SATA storage hardware that existed at that time (ironically, HDDs), but NVMe was designed independently and cannot be applied to existing storage hardware. NVMe would be worthless for use with HDDs, since they cannot even keep up with what AHCI provides.

While SSD users are still stuck with file systems designed for HDDs, NVMe is a major step beyond AHCI.

I tried to load the Intel IRST "F6" AHCI driver into my SM951 once, but it did not work, and I was afraid to keep trying.

One odd thing I've found while using the SM951 (AHCI) is the Intel IRST Windows UI will not install when you install the Windows IRST driver and UI package. The IRST installer just hangs at the end, which is the UI installation stage. I must kill the process with Task Manager. The IRST driver was installed, but the IRST Windows UI won't. Even the latest IRST 14.5 version failed to do so.

Fortunately when UEFI booting Win 8/8.1/10, the Ctrl i Intel RAID OROM interface becomes an option in the Advanced section of the UEFI. So I have the basic IRST RAID creation and deletion features, but not the entire IRST Windows UI feature set.

Yet another interesting thing I learned while installing Windows on the SM951, if you don't have at least one drive connected to the Intel SATA ports, you cannot install the Intel IRST driver. Both the F6 and Windows IRST package fails to install until a drive is connected to the Intel SATA ports.

Interesting how the SM951 will choose, or be assigned, the Windows AHCI driver during a Windows installation, while the IRST driver included with Windows could be used. Well, that driver might only be the RAID driver and not the AHCI driver.
