Step 2: Install memory modules

The motherboard has 3 dual inline memory module (DIM M) sockets, but it can only support a
maximum of 4 banks of DDR memory. DDR slot 1 uses 2 banks, DDR slot 2&3 share the remaining
2 banks. P lease refer to the follow ing tables for possible memory configurations supported. The
BIOS will automatically detects memory type and size. To install the memory module, just push it
vertically into the DIMM Slot . The DIM M module can only fit in one direction due to the notch.
Memory size can vary between sockets.
