Z790 Motherboards, 13th Gen Intel Processors and 128 GB RAM support?

[encrypt1d]

The Asus support site says that the following kits are qualified for 128 GB of RAM, however the Socket support is listed as only "1,2" not "1,2,4". This is pretty confusing. Are these kits actually going to run 128 GB of RAM at 5200?

The "1,2" in the socket support column is telling you that it's only validated using 2 DIMMs out of the 4 DIMM kit.  I don't know if there are any DDR5 examples, but historically I've seen 8 DIMM kits of DDR4 listed on the QVLs for boards with 4 slots.  The size column is telling you what's in the kit for the listed part number, not the maximum supported config; the socket support column is telling you which configs (1, 2, or 4) have been validated.

BUYERS BEWARE - despite the fact that they have a "validated" 4-DIMM kit on the supported list - it is not guaranteed to work as a 4-DIMM kit. 

Honestly, this needs to be made much more clear in the documentation. I find it dishonest as it is written now.
