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.
