What Cisco UCS C4200/UCS C125 M5 Rack Server Node DIMM type is supported?

RDIMM

Why are there various DIMM types supported?

Factory configured C4200/UCS C125 M5 Rack Server Node systems often have smaller, less expensive modules. As more memory is required different density and technologies are needed. DIMM type mixing is never recommended.

What is a registered memory module?

Registered DIMM memory modules have a register component between the DRAM modules and the motherboard memory controller. When manufactured as a dual in-line memory module (DIMM), a registered memory module is called an RDIMM.

What Cisco UCS C4200/UCS C125 M5 Rack Server Node memory speed is supported?

DDR4-2666, DDR4-2933 and DDR4-3200

Why may there be various speeds of Cisco UCS C4200/UCS C125 M5 Rack Server Node memory?

Some servers often have various configurations and versions. If you are unsure what you need, please refer to your C4200/UCS C125 M5 Rack Server Node manual or data sheet. If you need tech support, please contact us.

General DIMM population guideline for Cisco UCS C4200/UCS C125 M5 Rack Server Node upgrade to consider.

Some may or may not apply.

• If mixing memory speeds, all 16 DIMMs run at the lowest DDR4-2666 bus frequency.
• Install DIMMs starting furthest from the processor.
• Do not install DIMMs if the corresponding processor is not installed.
• If only one processor is installed in a two CPU system, only half of the DIMM slots are available.
• To maximize performance, balance the total memory capacity between all installed processors.
• It is not required, but it is recommended to load the channels similarly if possible.
