Note that on Z170 raid0 more than 2 pcie ssd will be useless as DMI 3.0 limit to ~4GB/s

Would this allow support of ahci m.2 pcie ssd's that aren't detected on older uefi's? Im trying to get a samsung sm951 ahci ssd to work with an asus rampage iv extreme.

thanks

Hi imsims. I've got the same set up - sabretooth x79 with the 4801 bios. Just tried the intel 750 but win 10 install says it cannot use it as a boot drive. Did you do anything else to get it to work as a bootable option? Which pci-e slot are you using?

Many thanks

Ben

New RST14 (for Z170) does support boot from NVMe drives without own bootloader like SM951 NVMe.
Did somebody already try to integrate RST14 modules into X79 UEFI?

The new Intel Rapid Storage Technology v14 for Z170 does support PCIe/NVMe RAID. But you are right, it's not bootable.
I'm still looking for a solution to boot my X79 system from a Samsung SM951 NVMe.
I was hoping for ASUS to come forward and bring this to X79 so i could use that UEFI modules. But it seems their poll was just a poll.

get an intel p3700 or 750 for X79.

Do I need to insert the nvme modules at a specific "volume"? I'm using a Gryphon Z87, same as this post.

today arrive my new Intel P3700 , thanks to amazon for getting back my 750.

@Fernando

this just to confirm that on my Asus Sabertooth X79 with last bios 4801

Both Intel 750 and Intel P3700 are fully bootable without any bios mod.

I have now tried to make the Intel 750 a bootable drive on a ASUS P8Z77-V with a modded bios, but to no avail. My steps were as follows:

1) I downloaded the latest official BIOS from asus.com
2) I inserted the NVME-modules from the ASUS Z97 mainboard published in this thread into volume 02 alongside CSMCORE using MMTool ("Insert FFS Options: Insert Compressed").
3) After carefully naming the bios file "Z77VB.CAP" I flashed the modded bios onto the mainboard using ASUS' "USB BIOS Flashback".
4) After rebooting I ran "Load optimized defaults" in the BIOS and after yet a reboot I started the Windows 8.1 installer from a USB flash drive.
5) The Intel 750 was recognized by the Windows installer, but it would not let me install Windows onto it, claiming the drive was not bootable by the computer BIOS.

After this I tried all kinds of various BIOS Settings:
Fast boot = Disabled
OS type = Other OS
Boot device control = UEFI only
CSM options = Loading UEFI-modules first

But none of these changes could convince the Windows installer to accept the NVME-drive as a system drive.

For what it's worth, when the Intel 750 is connected the BIOS shows a "PATA SS:" drive as a possible bootable drive, both with the stock and modded BIOS'. The drive is placed in the black PCI-E 2.0 slot of the mainboard, as this is the only slot that makes the drive turn on. In this slot the drive works wonderfully as a non-bootable storage drive in Windows 7, Windows 8.1 and Windows 10.

Any ideas what I could try next?

The drive has one partition that is formatted as NTFS and contains some files. It has no boot record. Would it be worth trying cloning a working Windows installation to the drive and see if that works?
