Installing or removing a memory module
This topic provides instructions on how to install or remove a memory module.
Note: The memory modules are sensitive to ESD. Ensure that you read and understand “Handling
static-sensitive devices” on page 54 first and carefully perform the operation.
Memory module installation rules
Your server has four memory slots to provide the following features:
• Each slot supports 2 GB, 4 GB, and 8 GB double data rate 3 (DDR3) unbuffered dual inline memory
modules (UDIMMs) with Error Checking and Correcting (ECC) technology.
• The minimum system memory is 2 GB (only one 2 GB memory module installed in the DIMM2 slot).
• The maximum system memory is 32 GB (one 8 GB memory module installed in each of the four memory
slots).
For more information about the memory modules in your specific server model, use the Setup Utility
program. See “Viewing information in the Setup Utility program” on page 37.
