I plugged the SM951 into a 4x PCIe slot. BIOS does not see it F2 or F3.
Windows 10 sees it but won't install to it (not bookable device).
If I install windows 10 on another drive and then clone to SM951 the bios sees it but won't boot off it even if I set as hard disk and first device in boot sequence (No boot device) when booting. When the BIOS first sees the device it thinks it is a floppy drive. This might corrupt the boot sector.
Clonezilla sees the drive and will clone it, but corrupts something on original windows 10 install and 10 will no longer boot. Also SM951 disappears from BIOS after cloning.
I did have a raid setup with 2 SSD's and when I first initialized SM951 in windows I got a Windows 10 boot device in the BIOS. (Don't know where that came from) Also UAFI device showed up in BIOS and when booting to it you can execute certain commands. Still learning.
If there was a way of forcing Windows 10 to install on the SM951 I think the BIOS would see it and could set it as first boot device. That's if it does not set it to floppy and corrupt the boot sector.
MBR vs GPT?
Trying to load some linux distros to the SM951. Is a different flavor of this board more compatible with NVMe?
Otherwise I'm sort of stuck. Might have to get a AHCI SSD but most slower. (OCZ) back ordered.
I am not really into nvme, but i 've never read of anyone being able to boot from it. Not in AM3+ at least. So before giving money for new motherboard, first make sure that you can use the nvme as bootable. Cause i don't think you can.
Went to a friends house that has a ASRock 970A-G/3.1 AM3/AM3+ motherboard booted windows right up from Samsung NVME in it's M.2 slot. I had a windows 10 clone on the drive also and it just worked. Sold him SSD
So I think the Gigabyte Gamer board with M.2 slot would also work. But don't quote me on that. Gigabyte's website says it's NVME compatible.
Gigabyte makes a awesome board hardware-wise, hope they update the BIOS to boot from NVME.
I ordered AHCI version of same Samsung M.2 SSD, hopefully that will work.
