IMPORTANT: A maximum of 8 DIMMs are supported in a configuration with low line AC voltage
and 2 processors.
TIP: You can load DIMM pairs on a single riser at a time, but this option reduces system
performance.
Supported DIMM sizes
DIMMs seat onto the four memory risers that seat on the system board. The minimum server
configuration requires that at least one memory pair (group of two DIMMs) is installed on memory
riser 1.
Supported DIMM sizes:
• 4 GB
• 8 GB
• 16 GB
