Have we enabled the memory remapping feature in the bios ?
I would have a check to see if it is enabled.
The info says the board supports up 4x 8gb sticks for a total of 32Gb.
Does the board support the Xmp feature memory?
I had a look and, see no mention of it in the manual.
And the memory is not listed on the QVL list of the support page.
Maybe an Rma is in order, of the memory.
The only other thing to consider is would a bios update fix the problem.
