Is it not possible to setup a non VROC RAID Array with this board?  I have 2 970 pro M.2's in the 2 M.2 slots.
When I set the sata mode to RAID and reboot I get the Intel Rapid storage sub menu but when I go into it I get no option to create an array.

Not sure if I am configuring something wrong or not.  I am on BIOS 1.23.

    I don't think its possible to RAID them through SATA since both M.2 slots are tied to the CPU PCI-E lanes. They're not going through the chipset's lanes. I had to sell my two Samsung 970's and buy a couple of Intel 760p's to RAID them via VROC to make a bootable Windows drive.

    In order to use regular rst/chipset raid it has to be through the PCH lanes

    So I guess that means only sata drives connected to the sata ports then since only 1 of the M.2 slots can be changed to use a PCH lane.
    Makes sense now.

    There's also the x4 slot if you have an M.2 to PCIE slot adapter card.

    I have a radiator/fans blocking that spot,  Not really worth messing with.

    With the latest BIOS, you can use CPU lanes to create NVMe RAID in RST (instead of VROC). You have to enable "CPU Attached Storage" and disable VROC for those PCIe slots. Once "CPU Attached Storage" is enabled, your primary NVMe drive (if you have one) will no longer be bootable unless you set that PCIe slot to VROC and install the VROC drivers. This is a necessary workaround as otherwise the drive will be captured by RST and not be bootable.
     
    You can also create NVMe RAID in VROC using the VROC GUI in Windows. Non-Intel drives won't show up as RAID arrays in the UEFI, but the array is usable in Windows. Create the array on a secondary Windows installation so the trial doesn't expire on your primary OS.

    I'll have to look into that, thanks.

    I'll have to look into this but the one M.2 slot cannot be changed from CPU to PCH.  Only 1 of the slots can, At least I do not see the option to change the one slot to PCH.

    There's no need to change any slots to PCH and bottleneck the M.2 drives. You can create an NVMe RAID array using either VROC or RST (with "CPU Attached RAID" enabled) and only CPU lanes. VROC is definitely not bootable, and I don't know if CPU attached NVMe RAID on RST is bootable.
     
    If it's not bootable, you can try switching to PCH lanes for RST with "CPU Attached RAID" disabled. You can set either PM2 or PE6 to PCH lanes. PE5 is hardwired to PCH lanes. Get an M.2 to PCIe x4 adapter.
