The motherboard comes with four (4) Double Data Rate 4 (DDR4) Dual Inline Memory
Modules (DIMM) sockets.
A DDR4 module is notched differently from a DDR, DDR2, or DDR3 module. DO NOT
install a DDR, DDR2, or DDR3 memory module to the DDR4 slot.
The figure illustrates the location of the DDR4 DIMM sockets:
