Ok, this is the link of my bios.
http://dlcdnet.asus.com/pub/ASUS/mb/sock...3176.1508173072.

Other than this exist a newer version of the bios, the 2704, that is the latest, but the 2704, create only problems on my configuration (bios freeze and i/o peripherals not recognized). For this reason i use the 2403.

If you see on the Asus page:
https://www.asus.com/it/Commercial-Serve...pDesk_Download/

if you read on the bios 2304 you can see support of NVME device from that version.

@salvo00786,

Was wondering if you have tried placing the hyper card on every spare pci-e slot and do you get the same result? Also if you boot off of the onboard m.2 can you inside the windows environment see the Hyper m.2 card?
But you say the nvme drive works perfectly off of the onboard m.2 connector? Too bad you don't have a spare cheapo pci-e card to test things out with for comparison..

No, i can't place the PCIE card on every PCIE because the PCIE16x4 is the only slot that i can use. I have tried to boot the windows from the other normal ssd 850 PRO thet i have, but i can't see the pcie card in windows enviroment. Yes the OS works perfectly on the m.2 native slot. Asus support tell me that the Hyper M.2 is not tested with my ssd and, for this reason they think that is a problem of compatibility of the Hyper M.2 card with the 960 Pro.

I have seen another card: http://www.silverstonetek.com/product.php?pid=703&area=it

and silverstone tell that this card works with 960 PRO ssd. I don't know if is this the problem.

I would try doing running Win installation from Clover (it will bypass any UEFI BIOS issues).
That way you could confirm if it's UEFI or drive itself.

Run HWInfo64 and go down the pci-e tree it lists out and see if it detects your device. Curious.

The problem has solved. The source of the problem was power supply. It has unstable 3.3V line. Initially voltage was 3.116V and changing from 3.104 to 3.200. When HDD connect the voltage increase to 3.392V and become more stable. The PC boot and work well with other power supply.

@pVlady
I'm glad you figured out what the problem was. I would not have suspected the power supply if the PC was working fine with an SATA drive. Good job troubleshooting! Thanks for letting us know what the problem was.

Hello everyone. I didn't have time to read all the 150-ish pages of this thread, but wanted to ask a question about my AMD motherboard and nvme support.

I have Asrock 970 Extreme 3. Latest BIOS version is 1.80 and it doesn't support nvme. However, a more premium motherboard Asrock 970 Performance has nvme support added.
So the question is can I extract nvme support from the Performance BIOS and add it to my?
Since this guide targets Intel chipsets, is is even safe to try it on AMD chipset with provided FFS driver?

See attached file. It's a screenshot from the Performance BIOS.

Gigabyte Z97X-UD3H

Hello, I am trying my first hand to install to a m.2 NVME Toshiba RD400A into a Gigabyte Z97X-UD3H (1.2) BIOS F9. The bios will not recognize the drive at all unless I put the SATA controller in RAID mode. Based on Fernando's post it would seem this is not ideal? My go goal is to use all Fast Boot features without CSM and not have to use RAID mode for the AHCI. What settings are the ideal and or BIOS mods need to be made since I am sure the efi drivers for nvme are already incorporated into this BIOS?

@Sledge
Have you tried contacting ASRock technical support to see if they have a BIOS with NVMe support for your motherboard? They may already have a BIOS, but they don’t list them on their website for motherboards that did not come with an M.2 slot.
In my experience, ASRock Taiwan is more likely to have the latest BIOS, but I would try all three. Asrock Taiwan took a few days to get back to me regarding a BIOS for my motherboard, but they had the latest/best BIOS.

@Trinergy:
As you can read within the start post, the NVMe SSD will not be shown with its name, when the user enters the natively not supported BIOS. Nevertheless you will get full NVMe support with your Z97 Chipset mainboard, if you follow my guide.
Before you start with the OS installation onto the NVMe SSD, you should unplug all your other HDDs/SSDs and set the on-board Intel SATA Controller to DEFAULT mode.
Once the OS is up and running fine on te NVMe SSD, you can re-attach all your other storage drives after having set the Intel SATA Controller to the demanded mode.

Nevermind. I decided to update the bios anyway and it worked! Thanks again.
