Hyper M.2 Card - Only one drive recognized

Have an Asus Apex IX board running Dsanke mod bios for Apex X 2701. Just bought a Hyper M.2 Gen 3.0 V2 card with two nvme drives installed in M.2_1 and M.2_3 ports and only one drive gets recognized in Windows. Have enabled ‘Hyper M.2’ mode in bios however there are no other settings in bios for selection bifurcation modes. Have tried turning on Raid mode. Have tried other ports on the Hyper M.2 card and still only M.2_1 port works. Have also tried both x8 slots on the motherboard moving the gpu to other slot. No effect.

For right now using a 6700K and have the boot nvme drive installed in the Dimm_1 adapter card. My only guess is that the bios mod is incompatible with the motherboard. Not sure what is going on but understand this is a common problem.

Thanks

APEX X up it seems…
[Motherboard] Compatibility of PCIE bifurcation between Hyper M.2 series Cards and Add-On Graphic Cards | Official Support | ASUS Global

Yeah I saw that yesterday and didn’t fully take it in until late last night when I read that 4x/4x/4x/4x is impossible for most boards especially if there is a discrete graphics card installed in one of the 8x slots as it only allows max 1 disk to be recognized!

Without a GPU installed it bifurcates like 8x/4x/4x and only three disks are allowed! Maybe if you have a higher end AMD board with lanes in excess you can have 4 disks. In my case I have to give up the graphics card if I want 3 drives. The board is just not wired to bifurcate the first 8x lanes further and so no way to get a two disk array setup as the second m.2 disk just gets ignored.

So at this point think I will just use one of my 8X slots and the other 4X slot that is wired straight to the cpu and create a storage space and return the card or just shelve it as not sure I can even though return it considering its no longer in a like new condition. Only cost $40 something dollars.

Small loss but personally think that there should have been better information out there detailing all the pitfalls.
