A:Answer This could...and should...have been a LOT clearer in the promotional materials.
My AN515-53-55G9...in a sealed box at the store...came with 1-stick of DDR4-2400 RAM, although all the literature strongly implied it came with DDR4-2666, and no one from the store could tell me otherwise.
Memory Module Brand/Model as received was:
per CPUz = SK Hynix SO-DIMM 8GB, DDR4-2400, CL17-17-17
Module Label = sk Hynix 8GB 1Rx8 PC4-2400T-SA1-11
