For those running a Gigabyte ME03-CE0 – have you actually been able to get bifurcation working on any of the PCI slots? Ive got a pci card which takes two nvme drives, and can’t get them to both show when running the x16 slots at x4 x4 x4 x4. I’ve tried all other slots (set to x4 x4 x4 x4) at this point too.
Starting the think getting this board was a mistake (see other threads I’ve responded too).
Got it working. I cleared CMOS again, and switched the pci card to PCI_6 (top slot) in 4x 4x 4x 4x mode. Not sure which of those two changes fixed the issue, but it isn’t the first time I’ve cleared the CMOS.
Still unable to use any drives connected via MCIO headers however.
Thanks for sharing. Which card is that you use and need to tweak bios?
I have the same motherboard and with two ASUS Hyper 5.0 x16 cards (total of 8 NVME slots on the two cards), it is automatically detected correctly in the upper slots. No Bios tweaking needed.
It is an ICYdock which takes two NVME (external access).
