Dell PowerEdge XE9680L upgrade kit

This 1.5TB memory kit is built for the Dell PowerEdge XE9680L rack server. It contains twelve 128GB modules that install directly into the system's DDR5 RDIMM slots. The kit targets administrators who need maximum registered ECC capacity in a single qualified package.

6400MHz CL52 registered ECC spec

Each module runs at 6400MHz with a CAS latency of 52 at 1.1V. The 4Rx4 organisation and 288-pin RDIMM form factor match the platform's registered ECC requirements. This speed and latency combination is the decisive factor for compatibility with the validated server configuration.

1.5TB total capacity headroom

The twelve-module population delivers 1.5TB of registered ECC memory for large-scale virtualisation, in-memory databases and HPC workloads. Capacity scales to the platform's supported limit, so headroom ends when all approved DIMM slots are filled.

Questions about this item

What does the 6400MHz rating mean once the modules are installed in the Dell PowerEdge XE9680L?

The kit runs at DDR5-6400 speed, delivering 6400 MT/s data rates per module when the server's memory controller operates at that frequency.

What does the PC5-51200 designation tell me about the memory interface?

PC5-51200 is the industry label for DDR5-6400 modules, confirming the 288-pin DDR5 RDIMM form factor and registered ECC operation.

What physical slot and clearance do these 128GB RDIMMs need in the XE9680L?

Each module is a standard 288-pin DDR5 RDIMM without a heat spreader, so it fits any compatible DDR5 RDIMM slot in the server.
