The L9a is not compatible with am4 out of the box and would require the separate mounting bracket, the L9a-AM4 is the one that is compatible out of the boxOk so you must have purchased the L9i which requires that AM4 mount kit. The L9a is AM4 out of the box. Easy to mix the two as both show up as ‘AM4 compatible’ on some searches.
Good luck with the build!
The most likely reason is that it does work but somehow it doesn't in your situation.
Are you trying to use the RAID drives from another motherboard while keeping the data ? You need to set these up as RAID 0 and you will lose all data on those drives. The way to set these up is explained in the ASRock's RAID installation guide. It's not through Windows, you first need to configure a RAID array the way the manual describes it.
Check that you have the latest drivers, there is the AMD chipset drivers and RAID drivers (latest). Are you trying to load the drivers for a new Windows install ? It's not clear from your post that you are using an existing install or trying to do a new install.
I have a NVME SSD as my boot drive, yesterday I added 2 HDD's in RAID 0 following step 1.3 in the guide Phuncz mentioned and everythings working fine, perhaps windows has to be installed on the NVME drive before you setup the RAID?
Hi , I don't think I installed any raid drivers, I just followed the legacy RAID configuration section in the manual and its working fine.Hi, Have you tried running the latest raid drivers EXE from AMD, do you get any pop ups saying you can’t run the raid driver with NVME as boot drive?

yep I just tried it and got the same error, I'm curious this is the first raid array I've setup what benefit is there to updating the raid drivers?Maybe you can try and load the AMD Raid drivers from their website. - https://support.amd.com/en-us/download/chipset?os=Windows 10 - 64
Let me know if you get an error message, this is the one that I got. - "Windows is currently installed to an NVMe disk;upgrading the RAID driver will make this OS unbootable. Please load Windows on a non-NVMe disk. RAID installation will now abort"
NVMe Raid 0 (Add-In Card)
With the forthcoming Vega enabled APUs, I have been thinking about NVMe Raid 0 on my x370 Gaming/itx. Would it be bootable with an add-in card like Asrock's Ultra Quad M.2 Card? I know the x370 Gaming/itx supports Bifurcation to a 8x/8x level. The Ultra Quad M.2 card does not have any switches onboard, so would m.2 ports 1 and 3 (on the add-in) work for this request?
Is this something that has ever been considered?
(also, I know Dell and Asus make a 4xM.2 add-in that might work)
Edit: (Asrock's pin layout)
You ought to update to the latest BIOS version 4.51aEDIT: I should add I'm on bios 3.40.
