| Make sure you have CSM enabled. |

Your board should support the use of the SM951. There is a newer UEFI/BIOS version, which version are you using? What Windows installation media are you using, optical disk, USB flash drive, or something else? You won't be able to use a Windows optical disk for the installation, it should be a USB flash drive. What entry in the boot order list are you selecting for the Windows installation media device? Have you modified any settings in the UEFI to enable the installation and booting from a SM951? If you are not doing a full UEFI booting Windows installation (CSM disabled), you must select a setting in the CSM option. With CSM enabled, find the Launch Storage OpROM Policy, and select UEFI only. |

Greetings, this is ASRock Technical Supports Department. We provide some suggestions to you for try: 1. Please flash the BIOS to P1.20 as the link and set BIOS to default : http://www.asrock.com/mb/Intel/X99E-ITXac/?cat=Download&os=BIOS 2. Due to the SM951/XP941 limitation, please install the Windows with GPT(UEFI) mode. 3. Please use another USB device or another Windows media resource to install the system for try. 4. If possible, please use another memory to verify. Kindest regards, ASRock TSD |

This result is from our internal test. however, we also tested on another vendor's boards and the result is the same. Please check the info as below links: http://www.amazon.com/Samsung-SM951-256GB-AHCI-MZHPV256HDGL-00000/dp/B00VELD92U http://forums.overclockers.com.au/showthread.php?t=1137569 For further and clearly information, we recommend you to contact Samsung.

Hi, I also faced similar problem. My system: Intel Xeon E5-2683 V3 Crucial 32 GB ECC/Reg Ram (CT32G4RFD4213.36FB1) Gigabyte GTX 1070 itx graphics card. Asrock X99e-itx/ac System entered in UEFI properly and detected all the hardware correctly. Ram test (Memtest86, Memtest86+ and Windows memory test) passed in round-robin CPU selection but Parallel CPU testing restarted the system in middle (possibly a software bug of Memtest86+ or UEFI). CPU-Z showed correct processor and Graphics card. However, with default UEFI settings could not install Any OS (Windows XP, Vista, 7 and 10) and Linux (Redhat EL, Fedora, Debian, Ubuntu, OpenSuse) both 32 and 64 bit. Updated to latest UEFI (P3.60) but no success in OS installation. Started playing with so many parameters in UEFI (CSM, Secured boot and so on) but no success. Emailed Asrock customer support but no response. Once changed SATA mode to IDE and could install Windows XP 32-bit. Got some Hope but most of the hardware not supported with Windows XP 32-bit (detected only 1.4 GB RAM). Tried 64-bit XP and Vista 32-bit next but both failed in installation. Finally disabled CPU C-State in UEFI and could install OpenSuse 42.2, a 64-bit OS. Still do not understand if problem is in the CPU or in UEFI or in the motherboard hardware. Still waiting to get response from Asrock customer support. Never expected need to spend so many day's to Install first fully functioning OS in this system. Hope some one else will be benefited from this info. Thanks. |

I have a similar problem or looks similar. System spec: Asrock X99E-ITX/AC 2x16GB Corsair non-ECC DDR4 SDRAM 2400Mhz SM951 256GB NVME with Samsung NVME driver AMD R9 Nano GPU etc. This system ran Windows 7 x64 normally, until I swapped out the RAM for 2x16 GB Samsung ECC M393A2G40DB0-CPB (on the memory support list of this Mobo). Windows boot stuck at Starting Windows. Windows installation media boot from DVDRom also stuck at Starting Windows. Memory - extended test ok. Boot to safe mode on Win 7 x64 residing in the SM951 also ok. I pressed the Clear CMOS, so every setting is factory default. So a bit puzzling. Swap the memory for non ECC if you can and try. I posted my original problem in a separate thread on Asrock forum 3 days ago but no response yet. ------------- Steven |
