Thank you for the help

On the thread, there are some references to 'frying' cpu with the wrong gpu in. If I put the gtx1660ti in any of the pcie slots for cpu1 (ie slots 1,2,3,4 or 6) and attach power from the psu to it - is it possible to 'fry' the pcie slot or the cpu?

Not quite sure what they mean by that. you might not get enough power to the gpu if you don't put the gpu in the blue slots and it might not run properly.

I got a S2600IP4 board E5-2680V2 cpus installed. I would like to add a quad NVME card to it. It is currently running BIOS 02.06.0005. I am not seeing anywhere in the BIOS that you can set the PCIe configuration for splitting up a 16x into (4) 4x config. I see that the latest BIOS is 02.06.0007, do I need to upgrade to that version to be able to do this? I am not looking to boot off a NVME drive as I will be using them for VMs in proxmox.

OK, I loaded the latest BIOS for it 02.06.007. After loading the defaults and going through every option to reset previous values, I am not seeing anywhere to break apart PCIe root ports into logical units like x4/x4/x4/x4 for a x16 slot. I know SM calls this IIO, but with this intel board and AMI bios I am only seeing PCI link speeds where Gen3/2/1 can be selected. Right now only 1 of the NVME drives is showing up in the host OS.

Can anyone point in the right direction for setting things up here?

Pretty sure with this generation you need a nvme carrier with a PCI switch to do the bifurcation.

It is definitely looking like the S2600IP4 does not support PCIe bifurcation. I guess I might need to upgrade to a SM X9 board that does. Maybe this is another example of why Intel should not be in the MB business :D
