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.
Thread revival!
I got a PCIe to NVMe drive adapter and want to plug it into this board. I'm on SE5C600.86B.02.06.0006.032420170950
Can anyone who's fought this battle already tell me if this will work? If I need to upgrade BIOS I won't even do it. This machine has become too critical to our household and if I brick it it's all over lol.
Thanks!!

If you really have to plug a NVME drive into this motherboard, grab one of the m.2 non bifurcation cards in this thread:
Do you need the NVME drive to be a boot drive or just general storage. I could not get my S2600 MB to boot off a NVME.
A lot of the super cheap NVME cards do need some support from the MB to operate. Best path to get a NVME drive to work with the board is either get one of the non-bifurcation card or get a new MB that does support NVME directly.

Put the nvme in a laptop or other machine. install windows and complete the first boot. place drive in adapter and plug into motherboard. make sure bios is on efi boot. Should work. otherwise you can create a usb bootloader and keep it plugged in. I dont recall the name of the one I used. sorry. been a long time. But my last build with this board is still alive with dual 2660 hosting pharmacy software.
This is the adapter I would use: https://www.amazon.ca/dp/B08TBW12B8?ref=ppx_yo2ov_dt_b_fed_asin_title
Unraid should work. behaves like a bootloader in a sense. same thing, just have a bootloader on flash drive.
It's more whether the board supports this NVMe drives at all with this ol' BIOS
but if i recall they work at nvme speeds as storage. I Think the EFI just doesnt support booting to NVMe, not the the NVMe stack isnt in EFI. It shouldnt matter with a USB bootloader
Long story short, due to pcie issues, these run at pcie 2.0 speeds with latest bios. You have to downgrade bios to get pcoe 3.0 speeds. But if you got it working in unpaid, just use crystaldisk benchmark inside the guest OS
From the output:
• LnkCap:
• Speed 8GT/s, Width x4: The device is capable of operating at PCIe 3.0 speeds (8 GT/s per lane) and supports 4 lanes (x4).
• ASPM L1: Indicates that Active State Power Management (ASPM) Level 1 is supported.
• Exit Latency L1 <8us: The time it takes to exit from ASPM L1 state is under 8 microseconds.
• LnkSta:
• Speed 8GT/s, Width x4: The NVMe drive is currently operating at its maximum PCIe 3.0 speed of 8 GT/s on 4 lanes (x4), meaning it is running at full potential.
• LnkCap2 & LnkSta2:
• Supported Link Speeds: 2.5-8GT/s: Confirms support for PCIe 1.0 (2.5 GT/s), PCIe 2.0 (5 GT/s), and PCIe 3.0 (8 GT/s).
• Current De-emphasis Level: -6dB: This relates to PCIe signal integrity, showing the level of signal de-emphasis being applied for data transfer.
Summary
Your NVMe drive is running at PCIe 3.0 x4, which is optimal for the WD Black SN750 and similar drives, as this configuration provides a maximum theoretical bandwidth of ~4 GB/s. Everything seems to be performing as expected!
Great. So that means you are running the bios that retains 3.0 support . So you have nothing to worry about. I also forgot the pcie 2.0 thing only applied to latest bios with a V1 CPU. V2 CPUs are not affected. Happy camping!
