For best performance, populate both memory controllers equally when using an even number
of DIMMs. For example, if using two DIMMs, install them into Bank 0 and Bank 1.
See Chapter 2, "Servicing the System," for instructions to install a DIMM. See Chapter 4,
"System Board," for DIMM socket locations.
The following table shows possible memory configurations. Each bank contains one socket.
