Installing a DIMM
A memory module can be installed in only one way. Match the notch on the module
with the tab on the memory socket.
If you have one preinstalled DIMM in socket XMM1 and are adding a second
DIMM, it is recommended that you install an identical DIMM into the XMM3
socket. If you are populating all four DIMM sockets, use identical DIMMs in each
