BIOS 1.23 adds the x16 m.2/bifurcation option.

I was originally going to do the ASUS Hyper M.2 with 4x Intel 760p drives on a EVGA X299 Micro. Looking at my BIOS, it should have worked since PCIe bifurification is an option. 
 
The DARK can do VROC as I know someone doing 2x M.2 Intel 660p VROC so the ASUS card should work as well. 

I did 2 2tb 660p's in VROC without a key, BIOS 1.24 and while it worked since the 660p's are slow drives it was just not worth it.  

Apologies for bumping up an old post. I finally finished my x299 build, even purchased a VROCSTANMOD. I'm running 4x Samsung 980 PRO 1TBs in an Asus PCIE on lane 4 (and a WD 2Tb on PM1). Is there any recourse for setting up RAID? Or do I have to go with a HighPoint (I can't justify spending $1k on a PCIE4 4x4 card... it's nuts)? Wouldn't mind brewing my own BIOS.
 
I can see all my drives in both BIOS and Windows, but no chance of RAID...

I think those past updates just gave us the option to do Software RAID within the Windows OS with a bifurcated AIC such as the Asus one. AFAIK you still can't do Bootable VROC on anything but the small handful of M.2 NVMe's that Intel says are compatible. I'm currently using 2x Intel 760p NVMe's in Bootable VROC mode with the VROCISSDMOD key (the one for Intel only SSD's).

I had originally tried to run 2x Samsung 970 EVO NVMe's with the VROCSTANMOD key but it would never let me combine the drives, always showed them as separate. Intel really screwed the pooch by putting so many restrictions on this technology. I ended up selling the Samsung drives and getting the Intel 760p's. 

I think for my next build i'll just go with a single PCI-E 4.0 M.2 NVMe. That will give me slightly higher speeds than my 2 paired up 760p's. Think i'll go with a 4TB drive instead of 2x 2TB drives.

I'm running three Intel P760 drives in Raid 0 without a key. As for booting from none Intel NVMe drives in Raid, it's a no go on the X299 platform.

Intel is really going downhill... Look at this response https://community.intel.com/t5/Rapid-Storage-Technology/Latest-VROC-UI-comes-with-expired-self-signed-certificate/m-p/1275986#M9882 
 
I think I've been an intel fanboy for too long. I have a 760p too that I was going to replace with this array of Samsung 980 Pros... there's gotta be a better way than dropping $1k on that highpoint...

F.it I bought a HighPoint SSD7505... this thing better fly at $630....

ionutzuthere's gotta be a better way than dropping $1k on that highpoint...

 
Yes, IMO there is a better way (for non-boot drives), it is free and called Microsoft Storage Spaces.

With the newer BIOS versions, if you enable the "CPU Attached RAID" option in the UEFI and set the bifurcation to non-VROC, you can now create RAID arrays using the RST software in Windows instead of VROC. Previously RST was limited to chipset lanes. Both VROC and RST are just software RAID. VROC has a slightly better abstraction layer which hides the individual drives when the driver is not installed, but with RST the individual drives are visible without the driver. I don't believe there is any extra offloading done by VROC compared to RST - they're both done in the driver.
