While like in the old thread you cite, HP does provide some images of their motherboards, they have these made under contract by third-party suppliers, so HP does not have any schematics or wiring diagrams for these.  Additionally, the suppliers consider this "proprietary information" and do not release it to the public.

Go to the link HERE and you will be able to download version 5 of the technical and service manual.  Most Z400 owners don't know this version exists.

This covers both the v1 4-DIMM and the v2 6-DIMM motherboards.  Give this time to download to your workstation and then save it for your stash.  This has significant value to you assuming you own a version 2 Z400.
