*2 Only M.2_2 socket can support Intel Optane Memory.
*3 Intel Optane Technology is only supported when using 7th Generation Intel processors. Before using Intel Optane memory modules, ensure that you have updated your motherboard drivers and BIOS to the latest version from ASUS support website.
It looks like only 1 of the 2 M.2 ports on your motherboard supports Optane, make sure you are using the correct one and make sure that your have the latest BIOS.
All 6 of your SATA ports appear to be Intel so that should not be an issue.

We were just checking this post and would like to know if you had the chance to test the Intel® Optane™ memory module in a different M.2 slot as suggested by nosirrahx? If so, was the system able to recognize the module?
