I have a feeling this might be incorrect and that if any M.2 drives are present in the DIMM.2 the x16 will only run at x8.

Your feeling is right 😉
I put a M.2 in the DIMM.2_2 and the x16 only run at x8 😞
So, the DIMM.2 is useless for me.

DIMM.2 is primarily for users that want to harness the full bandwidth of high-perf drives in RAID configurations. If you don’t care for that, use the M.2 slots under the heatsink. They are routed via the PCH.

There are only 16 CPU PCIe lanes. Multiplexing those lanes would eat into the available bandwidth for all associated devices. The reason to use primary lanes for storage is to get around the limitations of DMI. And it makes sense to put those slots on the DIMM.2 module because there is potential for higher throughput which will generate more heat than drives tethered to the DMI bus. The Extreme and Gene also have two onboard M.2 slots that are wired via the PCH. Use those if you want to devote all CPU PCIe lanes to graphics and/or other expansion cards.
