ASUS KRPA-U16 PCIe bifurcation


Mar 20, 2021
Is it possible?

I need an NVMe raid (2 x 2TB) for now, was thinking of going up to 4 x 2 TB. Got an ASUS Hyper M.2 X16 G4 and was hoping to set up all of the drives on the adapter.

But it only works if I have 1 SSD installed. Hey, it's good enough for now, 1 in the adapter and one in the M.2 slot on the mobo.

I know it's unsupported officially, but is there really no way to make it work? No bifurcation setting in the BIOS.

I guess I'll just have to sell the adapter and get some cheap adapters from aliexpress or something so each drive is on a separate PCIe slot if it won't be possible to get the ASUS adapter to work.

Oh, and I've got another limitation: I'm afraid I'll have to stick to my 0302 version because I've got an engineering sample (and I've only got a modded BIOS just for this version).
