Memory module installation rules
Your server has 20 memory slots.
• Each slot supports 4 GB, 8 GB, and 16 GB DDR3 RDIMMs.
• Your server supports up to 12 normal RDIMMs when one microprocessor is installed and up to 20
RDIMMs 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 for RDIMMs is 320 GB (two microprocessors installed and one 16 GB
RDIMM installed in each of the 20 memory slots).
