128GB DDR4 2933 ECC RDIMM for servers

This registered DDR4 module delivers 128GB of error-correcting capacity in a single 288-pin stick. It targets administrators expanding memory in compatible Samsung server platforms that require registered ECC DIMMs.

Capacity headroom at 128GB per slot

The 4Rx4 organisation provides high density for virtualisation, large databases and memory-intensive workloads. Systems with limited DIMM slots benefit most; configurations needing lower latency or fewer ranks per channel may hit timing constraints.

Registered operation at 1.20V

The module runs at standard DDR4 voltage without a heat spreader, relying on server chassis airflow for cooling. Registered buffering adds negligible power draw while improving signal integrity in heavily populated memory channels.

Questions about this item

Will this 128GB 4Rx4 DDR4 2933 module run with my existing 1.2V RDIMMs on the same server board?

Yes, it operates at the standard 1.2V DDR4 voltage and uses the 288-pin RDIMM form factor, so it can share a channel with other registered ECC modules of the same speed and voltage.

How can I confirm the stick is detected at 2933 MT/s with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode; it should report 128GB, 2933 MT/s, CL21, 4Rx4 organisation and ECC enabled.

Does the package include only the single 128GB RDIMM or are there extra parts like a heat spreader?

The box contains one 128GB 288-pin DDR4 2933 CL21 4Rx4 1.2V ECC RDIMM; no heat spreader or additional accessories are included.
