It will be interesting to see if the SM951 (AHCI or NVME) is compatible with an AMD board. It should be since ASRock has been great for keeping the UEFI/BIOS for their boards updated to work with these SSDs. We know it works on Intel boards, but I have yet to see an AMD board working with one of these SSDs. NOT that I've seen them not work, but I want to confirm that AMD has provided the appropriate SATA Option ROM that allows them to work. There are two aspects of compatibility, simply being recognized by the board, and then if it can be used as a boot/OS drive. There is a SATA Option ROM that is part of the BIOS file that provides full compatibility. The Samsung XP941 SSD is listed in this board's Storage Support List, when using the L1.12A Beta BIOS. That version should allow the SM951 AHCI version to work as well. The standard BIOS version 1.30 and newer should have the support for these SSDs that is included in the L1.12A Beta BIOS. Regarding BIOS changes, in order to make these SSDs bootable you must enable a sub option of the CSM option, found in the ACPI Configuration screen. With CSM Disabled, set the Launch Storage Oprom to UEFI Only. If you have a UEFI booting Windows installation (CSM Disabled), you don't need to change the CSM option. The SATA mode in Storage Configuration for the AMD SATA ports should be set to AHCI or RAID. Please let us know how the SM951 works for everyone on this board. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

Thanks for Your post parsec. I have not done any changes in my 1.5 BIOS. My SM951NVMe does not show anywhere i BIOS (anywhere I look....) I'm not realy into this BIOS.... It is shown in My Computer and in Device Manager. When SM951 are the only SSD the will BIOS restart when ordering exit. To get going the, another SSD has to be Attached. When installing W10 b.10166 from DVD, installer program do not find any Place to load. I take trying this as an Experiment, but I always take Experiments seriously :) Hope for help an education Finn ------------- A88M G-3.1 2x4GB XMS SM951NVMe NanoPSU MediaPC |

Finnipinni, let's start over. First, what board do you have, it seems to the the Fatal1ty 990 FX Killer, is that right? The goal is to be able to use your NVMe SM951 as a boot/OS drive, and for it to be seen in the BIOS. I made a mistake in my earlier post, very sorry about that! I meant to write this: Regarding BIOS changes, in order to make these SSDs bootable you must enable a sub option of the CSM option, found in the ACPI Configuration screen. With CSM Enabled, set the Launch Storage Oprom to UEFI Only. I wrote, "With CSM Disabled...", Disabled is wrong. CSM must be Enabled for the other options to be seen. So to be clear, with CSM Enabled, set the Launch Storage Oprom to UEFI Only. That is only the beginning, other things in the BIOS must be set correctly. They are: In Advanced/Storage Configuration screen, SATA Mode must be AHCI or RAID. In Advanced/Storage Configuration screen, set AMD AHCI BIOS ROM to Enabled. I'm not 100% sure this needs to be Enabled, you can try it both Enabled and Disabled. In Advanced/Storage Configuration screen, SATA IDE Combined Mode must be Disabled. That is the default in newer BIOS versions. Question: You have said many times that you cannot find the SM951 shown in the BIOS, right? Since your board has a M.2 port, there should be an entry for the M.2 port in the Storage Configuration screen, even if nothing is in the M.2 port. That is how it works with my (different) ASRock board. I must scroll down in the Storage Configuration screen to see the M.2 port entry. The SATA III ports are listed even if no drives are connected to them. The same should be true for the M.2 port. Are you sure there is no entry for the M.2 port on the Storage Configuration screen? Next, installing Windows. You may now know you cannot install Windows to a SM951 from a Windows 10 disk, it MUST be done from an ISO on a USB flash drive. If you don't know how to create the USB flash drive ISO installer, let me know. NOTE: For anyone using a Samsung NVMe SM951: You MUST use Windows 10! Only Windows 10 has a built in NVMe driver, no other versions of Windows do. Intel supplies a driver with their NVMe 750 SSD, but Samsung does not. No, the Intel driver does not work with a SM951. When you use a USB flash drive with a Windows 10 ISO, do you select it in the Boot Order screen in the BIOS? Do you see TWO entries for the USB flash drive, one that is "UEFI: Flash Drive", and the other, "AHCI: Flash Drive" in the Boot Order list? You should see these two entries in the Boot Order list, and you MUST choose UEFI: Flash Drive. Now we will assume you have booted from a Windows 10 ISO on a USB Flash Drive. The Windows installer is running, and you are on the Standard or Custom install option screen. You MUST choose the Custom Install option. In the Custom installation screen, you should see the SM951 listed. If not something is wrong, quit the installation. If the SM951 is listed, great! Next, delete ALL the partitions on it! All the space should be Unallocated. Then click on New to format the SM951. You'll see a message about extra partitions being created, just click Ok. When that is done, you should see four partitions listed from the format. Select the Primary partition for Windows 10, and continue with the installation. It should go quickly. It is more difficult to manually format the SM951 with all the REQUIRED partitions that the Windows installer will create automatically. Let Windows do the formatting in this situation. Let us know if any of this helps you get Windows 10 installed and running on a NVMe SM951. If it does, it will be the first time I've known that to work on an AMD board. Otherwise I'll see what else I can do to help you. One more thing I noticed about your board. The M.2 port is a PCIe 2.0 x2 10 Gb/s interface. Both of the SM951 SSDs are PCIe 3.0 x4 32Gb/s interface drives. You won't get the full performance from your SM951 unless your board has a PCIe 3.0 x4 32Gb/s M.2 port, sorry to say. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

First I want to thank you for your effort and nitidius work ! The main issue seems for me to be that M.2. is not listed. First, what board do you have, it seems to the the Fatal1ty 990 FX Killer, is that right? - YES ?€ ------------- A88M G-3.1 2x4GB XMS SM951NVMe NanoPSU MediaPC |

I reasently updated the BIOS from 1.4 to 1.5. In the prosess, it show a "checkerboard" where colors where changing as the prosess went on. I noticed that some of the squears diden't - an handfull stayed white. So if this fenomen is not what it should be - could it be the cause of M.2. not showing ? And would it be recomendable to repeet the prosess ? And how is this done the best way ? Many questions from me........ ------------- A88M G-3.1 2x4GB XMS SM951NVMe NanoPSU MediaPC |

So I'll be the first ? (never in my life before) This morning I stumled over some cryptical letters : GPT. Investigating this learned me that any NVMe must be GPT - NOT MBR. (formatting means establishing MBR - no other chois that I could find) So do this at first : In BIOS : Storage OpRom - UEFI only Video OpRom - Legacy only ---------- Advaced/Storage Conf. SATA C. - Enabl. SATA Mode - RAID mode Onb.raid 3TB+ - UEFI mode for GPT SATA IDE Comb. - Dis. Note that SM951 are not shown anywhere. SATA3_5 Samsung 850 (GPT) -------------------------- The instaler program is now running. The SM951 are shown in 2 paritions. Be shure not to choose the EFI part. No need for formatting ! And this Pc stopped in the reset program an screen went black - it had to be stopped by holding the button Down for as long as it takes to force it to stop.
Then after update : All Works fine :) -------------------------- In Windows/ThisPc - only SM951 and Intel 520 are shown In Disk manager SM951 = disk 1 - Intel 520 = 0 ------------- A88M G-3.1 2x4GB XMS SM951NVMe NanoPSU MediaPC |

That I haven't investigated, but I will think so. I'm an retired Electronic tecnician. These matters are all new to me.
The GPT protocoll is - as I understand - to take over for the older MBR. All types of disks can use this. Disks over 3TB MUST. So we wil learn to make use of it no matter. UEFI BIOS is also a must for using GPT. In all this - I belive an AHCI wil work following the precidure. So get going - and good Luck With it :) ------------- A88M G-3.1 2x4GB XMS SM951NVMe NanoPSU MediaPC |

After alot of coffe, little update to my earlier posts. UEFI has taken over for the old BIOS in 2007, now running version 2,5. Got my first mobo with UEFI about 2011, so it's about time to make full use of it ! Today all equipment are UEFI combatible. Only the disks needs any "tampering". UEFI format disks in GPT(GuidePartitionTable) To make use of both MBR- and GPT -disks, CSM has to be "fiddled" with. Running GPT on all internal disks means you should disable CSM. In UEFI Mode, Windows 10 installer program will not find an MBR disk (in UEFI called Legacy disk). And will not find any place to load. So, in UEFI the OS-disk has to be formatted in GPT in advance, regardless of disk type. Rest of the disks may be formatted in GPT when W10 is installed.
1. Format 2. Choose Delete Volume. 3. MBR to GPT. 4. R.click unallocated volume/new simple volume, and follow the precidure (Next all the way). You can label the disk later. In Command promt (admin) : Type diskpart/list disk/select disk 1 (the disk number) clean/convert GPT Both ways will cleene the disk completly, so backup all you want to keep ! ------------- A88M G-3.1 2x4GB XMS SM951NVMe NanoPSU MediaPC |

This is 128Gb SM951 Ahci version. As we know the board is PCIe 2.0 x16 so the results is not so good. Unfortunately NO PCIe 3.0 AMD board on the market. Windows 10 - FX 8320 - 16Gb  http://i.imgur.com/7WDFXSG.jpg?1" rel="nofollow - http://i.imgur.com/7WDFXSG.jpg?1 |

I am thrilled you got your SM951 booting! It is booting Windows, right? You are Norwegian (so am I, a little bit, and Danish too), and your English skills are good. But it is hard for you to describe these things, right? I'm not sure if I understand everything you wrote, so I want to review it to be sure. I hope you will do that for me, please. One other thing first. When I write UEFI/BIOS, I do that so people will start using UEFI as the name of the firmware on our mother boards. We do not use BIOS firmware anymore, but most people still call it "BIOS". I do that so people know when I write UEFI, I mean what they are calling BIOS. You are right that we either have UEFI or BIOS firmware. We now only have UEFI firmware. The CSM, when Enabled, runs the UEFI firmware in emulated BIOS mode. That means none of the advantages of UEFI firmware is used, which is terrible. Setting CSM to Disabled allows all the features that UEFI firmware has, to be used. But when really using the UEFI firmware, with CSM disabled, Windows must be installed with a GPT partitioning type, and will then use the Windows EFI boot loader. But to use the EFI boot loader, that normally requires an EFI compatible storage Option ROM to be used, which is part of the UEFI file. I have been installing Windows on regular SATA SSDs to boot from the Windows EFI bootloader. That is what happens when you have GPT partitioning of the SSD, and have CSM disabled as you said you did in your post above, right? When I am using Intel mother boards, I set CSM to Disabled. I then set the SATA mode to RAID. Those two things cause the EFI compatible storage Option ROM to be used during the Windows installation. I also must load the Intel "F6" Intel RAID driver, or the SSD will not be seen by the Windows installation program. I do not format the SSD at all. After I load the F6 RAID driver, the SSD is then seen by the Windows installation program. I then click on "New", and Windows formats the SSD as GPT, and creates three other partitions, that are needed for a complete EFI booting Windows installation. I'm not saying formatting the SSD before the installation as GPT is wrong, I don't know if your Windows installation has all the partitions that mine do. Your method seems to work fine. I have an ASRock 970 Performance/3.1 board, that uses the same AMD Southbridge (SATA) chipset as your ASRock 990FX Killer, so control of SSDs should be the same. When I tried to install Windows 10 in the same way on the AMD board as I do when I use Intel boards, the installation fails. I have the SATA mode set to RAID, and CSM set to Disabled. I cannot find an AMD F6 RAID driver that will work like the Intel F6 driver does. So the SSD is never seen by Windows. Your method, which seems to work, starts with the SATA mode set to AHCI, is that right? You did not say which SATA mode you used in your post. You also did not say what AHCI driver you are using. It seems to be the standard Windows AHCI driver, storahci. Or do you install an AMD AHCI driver after the Windows 10 installation. Next, you format the SSD as GPT in Diskpart. That can also be done in Windows Disk Management. You have CSM Disabled when the other two things are done, and then can install Windows fine, right? Do you the Windows disk, or a USB flash drive? I am curious about how your OS disk appears in Disk Management after the Windows Installation. This is how my EFI booting Windows 10 installation appears in Disk Management, the top entry:  That disk is really two Samsung AHCI SM951s in a RAID 0 array. That can be done now on the newest Intel chipset boards, like a Z170. That is my Window 10 drive on my ASRock Z170 Extreme7+ board. The 450MB Recovery Partition is actually two partitions, one is a hidden MBR partition that the Windows installation program put on the drive. That allows the installation to boot if CSM is Enabled. I'll try your method, but I don't think the result is quite the same as the way I do it. I also do not think an AMD RAID driver for the SB950 chipset exists that can use the EFI bootloader. I hope this makes sense to you, if you have questions about it, please ask. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

I've been using Windows installations on Intel systems for years by installing it from a USB flash drive with UEFI support. I've done that with Windows 7, 8, 8.1, and 10. The first board I did that on was an ASRock Z77 Extreme4. I do this with standard SATA SSDs, and AHCI SM951s. My ASRock Z170 Extreme7+ board has two AHCI SM951s in RAID 0, that is the drive volume shown in my Disk Management picture. Since some users are posting benchmark results, here's some of mine of the RAID 0 OS volume:   The USB Windows 10 installation media I used with my Fatal1ty 970 Performance/3.1 is the same one I've used to install it on three different Intel systems. I've never had a problem installing Windows this way until I tried it on my AMD board. You did not mention one thing that is essential for the system to really be UEFI/EFI booting. That is an option in our board's UEFI that must be set a certain way. That option is...  With that option set in my Fatal1ty 970 Performance/3.1 board's UEFI, the target SSD for the Windows installation is never seen by the Windows installer. That is the issue I have. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

| Ask "aberdeen" , he use 970 Performance. |
Posted By: parsec
Date Posted: 25 Oct 2015 at 1:04am
net2paul is correct. That is simply because the M.2 port on the Fatal1ty 970 Performance is PCIe 2.0 x4, while the Fatal1ty 990FX Killer's M.2 port is PCIe 2.0 x2. The difference between these two boards is not because of the chipset (990 vs 970) but simply due to the PCIe 2.0 lane allocation to the M.2 port. As we know, the SM951 has a PCIe 3.0 x4 interface. So not providing that to this SSD will result in reduced performance. Using PCIe 2.0 x4 will not allow the SM951 to perform at its best, and using PCIe 2.0 x2 will result in a further reduction in performance, sorry to say. A single SM951 in a PCIe 3.0 x4 M.2 port looks like this:  The Fatal1ty 990FX Killer board was released in April, 2014. That was before the SM951 and XP941 were available. The only M.2 SSDs available at that time, if they even were available, were SATA M.2 SSDs. The PCIe 2.0 x2 M.2 interface was mainly designed for SATA M.2 SSDs, and is more than enough to allow them to perform at their best. The Fatal1ty 970 Performance was released in November, 2014, and by then the Samsung XP941 was known to be coming. The XP941 uses a PCIe 2.0 x4 interface, so the M.2 port on the 970 Performance was changed to PCIe 2.0 x4. Don't you hate how fast some PC components change sometimes...  ------------- http://valid.x86.fr/48rujh" rel="nofollow">

I'm interested if anyone's managed to do a M2 Win10 install on a Fatal1ty 970 Performance. Particularly as that's the board I'm now considering. This thread also very helpful in making me realise the M2 socket bandwidth on the Fatal1ty 970 Performance is 20GB/sec bandwidth compared to 10 GB/sec on ASRock 990FX Killer. Is seems very strange for ASRockto half the M2 channels on the 990FX, which I guess is a later board. I'd been considering he 990FX, but as M2 support is higher on my list than NVIDIA® SLI support the 970 Performance looks a better bet.
and earlier:
Your Windows 10 installation appearance in Disk Management shows the WIN10INSTAL as FAT32 (I think that's on your Intel board), then that could be your problem as you say your trying the same USB installation on the AMD. Have you instead tried, as net2paul suggested, making a new USB installation, then installing with the single M2 being the only drive present? His install is showing just the SM951 SSD (C:) yet no install ?? |

  As you can see, I use PCie Card Adapter that working great with Samsung SM951 and Asrock 990FX killer mainboard. I put on PCiE 2 the card with SM951 and the video card on PCie3 slot. No change on Bios. Windows10 booting without issues !!!! Here is the PCie card wendor link : http://www.aliexpress.com/item/Adapter-Card-to-PCI-E-x4-for-M-2-NGFF-SSD-XP941-SM951-M6E-SSD-half/32389529832.html" rel="nofollow - http://www.aliexpress.com/item/Adapter-Card-to-PCI-E-x4-for-M-2-NGFF-SSD-XP941-SM951-M6E-SSD-half/32389529832.html So we can double the SM951 speed on 990FX killer and don't need to downgrade to 970 Performance ! Also you can put a second slower M.2 card on mainboard.

net2paul, Nice, Nice, Nice!!I'm thrilled with your results for your SM951 on an AMD board! I was worried, for certain reasons, that an SM951 would not work well on an AMD board. Is the SM951 and adapter card in a PCIe 3.0 slot? It seems to be. Your benchmark results are very good, with one exception, the 4K results are a bit low. That is just me as an SSD enthusiast judging every last thing, so forgive me for that. Questions: How did you format the SM951 when you installed Windows? Did you let the Windows installer program format it, or did you do it? What BIOS settings did you change for the SM951? AHCI or RAID mode? Any changes to CSM? If you can tell us how you did your Windows 10 installation, that would be useful information for other people! ------------- http://valid.x86.fr/48rujh" rel="nofollow">

First of all you don't format or partitioning SM951 !!!!! Asrock 990FX with the latest bios! U need to create a Windows 10 USB (GPT) installations media with UEFI support (GPT) Use RUFUS . Tutorial for RUFUS and Download http://www.windowscentral.com/how-create-windows-10-usb-installation In UEFI set AHCI and GPT. Mount SM951, No other drive. Boot directly from USB (GPT) with Win10 installer. Let Windows to configure your drive. In UEFI showing a new drive in BOOT menu something like "Windows Media". I'm not enter to UEFI right now but you will recognise it. Good luck ! Great thanks to Finnipinni !!!!
You post a benchmark results with 2 x SM951 in raid0. If you divide the results you will receive approximately the same results. But with intel board you use PCie 3 , not PCie 2 like AMD boards. Asrock 990FX M.2 PCie 2 x 2 With PCie slot nr 2 the Adapter can use PCie 2 x 4

I already posted this result in another post under my RAID 0 results. This is one SM951 on my Z97 board. Here it is again:  The other RAID 0 results show the RAID scaling is poor, either the RAID driver is holding these SSDs back or we've already used up the bandwidth. So dividing by two does not work for the new RAID for PCIe SSDs. It does work for SATA SSDs in general. net2paul, You are not understanding me, or I'm not understanding you, about formatting the SSD and using a USB flash drive to install Windows. When I install Windows on my SM951s or 950 Pro (or any SSD that I want to use the EFI bootloader for the Windows installation) using Intel chipset boards, I never format the SSD first. I always let the Windows installer program do that. When I tried the same technique on my 970 Performance board, it would not work. I've installed Windows like this for years on Intel boards, but the 970 Performance refused to work that way. Someone in an earlier post said they formatted the SSD as GPT before the Windows installation on an AMD chipset board. That worked for them. That's why I asked you what you did. You wrote this: "In UEFI set AHCI and GPT." AHCI is obvious, but how are you "setting GPT"? You also wrote: "Boot directly from USB (GPT) with Win10 installer. Let Windows to configure your drive. In UEFI showing a new drive in BOOT menu something like "Windows Media". "When you write GPT, I think you mean UEFI. The entry in the boot order will be "Windows Boot Manager". Never tried it again on my 970 Performance, but I will soon. ------------- http://valid.x86.fr/48rujh" rel="nofollow">

So installing Win10 on SM951 AHCI vers. on 970 Performance board is the same as on Killer. And Booting ! 1 No other drive just the SM951 2 Plug USB with GPT (not MasterBootRecord) USB with Win10 install created with Rufus 3 Go to UEFI Bios 4 Set in UEFI Bios on Storage configuration SATA MODE to AHCI MODE - everything disable, no AMD AHCI Bios . 4 Set Boot from USB UEFI 5 Boot and install Win10 6 On first restart unplug the USB 7 if Win10 installing go on next level , your are OK. That's all !!!
