Installing or removing a memory module
This topic provides instructions on how to install or remove a memory module.
Note:
The memory modules are extremely sensitive to ESD. Ensure that you read and understand “Handling
static-sensitive devices” on page 76 first and carefully perform the operation.
Memory module installation rules
Your server has 20 memory slots and it has the following features:
• Supports 4 GB, 8 GB, and 16 GB DDR3 RDIMMs
• Supports up to 12 normal RDIMMs when one microprocessor is installed and up to 20 RDIMMs when two
microprocessors are installed
• Minimum system memory: 4 GB (only one microprocessor installed and only one 4 GB memory module
installed in the CPU1 DIMMA1 slot)
• Maximum system memory if you are using normal RDIMMs: 320 GB (two microprocessors installed and
one 16 GB RDIMM installed in each of the 20 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 59.
