Module identity and purpose

This is a 32GB DDR5-4800 ECC RDIMM built with Samsung DRAM chips for registered server and workstation memory slots. The module runs at PC5-38400 speed with a CAS latency of 40 and operates at the standard 1.10V DDR5 voltage.

Who this suits and who it does not

It suits administrators upgrading or repairing systems that require registered ECC DDR5 DIMMs in a 1Rx4 configuration. Builders needing unbuffered UDIMM memory, non-ECC modules, or a different rank organisation should select a different part.

Deciding specification

The registered ECC RDIMM form factor with 1Rx4 rank organisation is the single attribute that determines whether this module matches the server memory controller and motherboard slot requirements.

Questions about this item

Will the DDR5-4800 RDIMM run alongside my existing DDR5-4800 ECC modules in the same server?

Yes, matching speed 4800 and CAS 40 lets this 1Rx4 registered module operate in the same channel as identical DDR5 ECC RDIMMs, provided your platform supports mixed-rank population per the system manual.

How can I confirm the 32 GB module is running at 4800 MT/s with ECC active after installation?

Enter the BIOS or use a hardware-info utility; the memory should report DDR5-4800, PC5-38400, 1.10 V, registered ECC and 1Rx4 organisation.

Does the box include only the bare 288-pin RDIMM or are heat spreaders and cables supplied?

The package contains the single 32 GB DDR5 RDIMM without a heat spreader; no extra cables or brackets are included.
