Hardware Installation Process
Step 2: Install memory modules
The motherboard has 3 dual inline memory module (DIMM) sockets, but it can only support a
maximum of 4 banks DDR memory. DDR socket 1 uses 2 banks, DDR socket 2& 3 share the
remaining 2 banks. Please refer to the following 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 DIMM module can only fit in one direction due to the notch.
Memory size can vary between sockets.
