I have no idea what it is you are asking sorry.
When you visit the ROG Exchange page (as of a few minutes ago) you see something like this:
Compatible Motherboards:Maximus V Extreme (from BIOS 1604)
Maximus V Formula (from BIOS 1604)
Maximus V Gene (from BIOS 1604)
Rampage IV Extreme (from BIOS 3602)
Rampage IV Formula (from BIOS 3602)
Rampage IV Gene (from BIOS 3602) If you check the drop down menu, the Maximus VI Impact is also an option, but that is apparently the only Maximus VI board that is compatible with ROG Exchange AFAIK. I believe if/when ROG Exchange will be made compatible with all of the Maximus VI series boards or, if it already is, when the page will be updated, is what is being asked.
I asked a very similar question a couple of months ago and was told, more or less, "We're working on it."
