Replacing a DIMM
WARNING!
To avoid bodily injury from hot surfaces, allow the server and its internal modules to cool before
touching them.
The server supports DCPMMs and DRAM DIMMs (both LRDIMM and RDIMM supported).
Compared with DRAM DIMMs, DCPMMs provide larger capacity and can protect data from getting
lost in case of unexpected system failures. RDIMMs can perform parity checking on addresses.
Compared with RDIMMs, LRDIMMs provide larger capacity and higher bandwidth.
Both DCPMMs and DRAM DIMMs are referred to as DIMMs in this document, unless otherwise
stated.
Guidelines
You can install only DRAMs or both DCPMMs and DRAMs on the server.
For DIMMs to operate at 3200 MHz, make sure the following conditions are met:
•
Processors that support the 3200 MHz data rate are used.
•
DIMMs with a maximum of 3200 MHz data rate are used.
•
Only one DIMM per channel is installed.
Guidelines for installing only DRAM DIMMs
When you install only DRAM DIMMs, follow these restrictions and guidelines:
•
Make sure the corresponding processors are present before powering on the server.
