Dell PowerEdge XE9680L server memory

This NEMIX RAM module delivers 128 GB of DDR5 registered ECC memory in a single 288-pin RDIMM. It is built for the Dell PowerEdge XE9680L rack server and uses major OEM DRAM from Samsung, Micron or Hynix. The module operates at 1.1 V without a heat spreader.

DDR5 5600 registered ECC limits

The DDR5 5600 interface runs at PC5-44800 with a CAS latency of CL46 and a 4Rx4 rank structure. Registered buffering and on-die ECC add command overhead that caps peak throughput below the raw transfer rate. Four-rank density also restricts the number of modules each memory channel can accept.

Upgrade from lower-capacity RDIMMs

Replacing smaller RDIMMs with this 128 GB module increases total memory without consuming extra DIMM slots, which is critical when the server's channel population rules limit rank count. The jump is worthwhile when workloads need more capacity per channel than existing modules provide and the platform firmware supports 4Rx4 devices.

Questions about this item

Should I pick the 128GB single module or combine smaller kits for my Dell PowerEdge XE9680L?

The 128GB module is sold as a single 1x128GB stick. Using one module per slot lets you reach high total capacity across the server's memory channels without mixing ranks or speeds.

What does the DDR5 5600 rating deliver inside the XE9680L?

The module runs at 5600 MT/s with CL46 latency at 1.1V, providing the rated PC5-44800 bandwidth when the server's memory controller operates at that speed.

How does the 288-pin ECC RDIMM interface limit performance in practice?

The registered 288-pin DDR5 RDIMM interface supports ECC error correction and 4Rx4 organisation, capping the module at the rated 5600 MT/s and CL46 timings within the qualified server platform.
