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 86 first and carefully perform the operation.
Memory module installation rules
Your server has 12 memory slots to provide the following features:
• Each slot supports 4 GB, 8 GB, and 16 GB double data rate 3 registered dual inline memory modules
(DDR3 RDIMMs).
• Your server supports up to six memory modules when one microprocessor is installed and up to 12
memory modules when two microprocessors are installed.
• The minimum system memory is 4 GB (only one microprocessor installed and only one 4 GB memory
module installed in the CPU1 DIMMA1 slot).
• The maximum system memory is 192 GB (two microprocessors installed and one 16 GB memory module
installed in each of the 12 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 63.
