7 Memory
7.1 Overview
The PowerEdge T310 planar provides six 72-bit (240-pin) sockets for DIMM memory modules. These
modules are DDR3-800/1066/1333 Registered/Unbuffered DDR SDRAM DIMMs. The modules are
configured as 72 bits wide to provide for error-correcting code (ECC). The memory controller in the
CPU performs the ECC.
The system supports a minimum of 1GB upgradeable to 32GB of RAM, using the following DIMM sizes:
• 1GB, DIMM Module
• 2GB, DIMM Module
• 4GB, DIMM Module
• 8GB, DIMM Module
7.2 DIMMs Supported
