Tampa 2 motherboard with Asus Hyper m.2 x16 gen 4 card

[scintillating]

Hey guys,

I recently bought an Asus Hyper M.2 x16 gen 4 storage card to add to my omen. It is currently installed in PCIE slot 1 with the GPU installed in slot 2. All 4 SSD's are installed on the card as well and all work just fine individually. With the card installed, I can only see one SSD from the card while the other three do not show up at all. I'm wondering if it is just not possible on the Tampa 2 motherboard or if it's just a simple BIOS setting I need to change. In BIOS the only RAID config option I see is for SATA RAID. I have that set to AHCI and don't want to change it unless it is absolutely necessary to get the gen 4 card to work. 

Thanks in advance,

Current set up

Gen 4 card- Asus Hyper M.2 x16 Gen 4 Card

SSD- WD_Black SN750 500GB (4 of these installed into the gen 4 card)

Motherboard- Tampa 2

CPU- i7-8700k

GPU- GTX 1080ti

Hi,

So, do you have the four card PCIe to M.2 adapter installed in the PCIe x16 slot (the PCIe slot closest to the CPU socket)? I am asking because I don't know if PCIe slot 1 or PCIe slot 2 is the x16 slot. The graphics card x16 slot runs from the CPU.

You will need 16 lanes for four NVME drives. Using the graphics card on a four or a eight lane slot (depending on how the alternative x16 slot is wired) means you are running the graphics card on truncated lanes from the chipset.

One of those PCIe slots may only be wired to provide four lanes from the chipset. So you only see one drive.

This is a chipset limitation and is not caused by HP.

I don't think RAID will solve this problem.
