illustration and table.

General DIMM slot population guidelines (ML110 G6 servers)
Observe the following guidelines when populating DIMMs:
Populate DIMM slots for a processor only if the processor is installed.
Do not mix Unbuffered and Registered PC3 DIMMs.
Each channel supports up to two Unbuffered DIMMs.
Single DIMM (non-interleaving) must be installed in slot 2.
Two DIMMs (interleaving) install in slot 2 and slot 4 for optimal performance.
