Server memory kit for Dell PowerEdge XE9680L

This 2 TB kit contains sixteen 128 GB DDR5 RDIMMs rated at 6400 MHz with CL52 latency and 1.1 V operation. It is built for the Dell PowerEdge XE9680L rack server and uses registered ECC modules for data integrity.

Capacity and headroom

Sixteen dual-rank 4Rx4 modules deliver 2 TB of registered ECC memory, suited for large virtualisation clusters and in-memory databases. The 6400 MHz speed and CL52 timing provide bandwidth for heavy workloads, while the fixed 16-module population leaves no free slots for further expansion.

Build quality and connectors

Each 288-pin DDR5 RDIMM uses major OEM DRAM from Samsung, Micron or Hynix and runs at 1.10 V without a heat spreader. The registered design adds electrical buffering for signal stability in dense server configurations, and the standard pin-out ensures direct installation in the XE9680L memory slots.

Questions about this item

Will the 4Rx4 DDR5 modules run correctly with the existing RDIMMs already installed in my PowerEdge XE9680L?

The kit uses 4Rx4 registered DDR5 modules at 1.1V; matching rank and voltage with existing RDIMMs is required for stable operation in the XE9680L.

How can I confirm the 6400MHz CL52 kit is running at its rated speed after installation?

Enter the system BIOS or use Dell iDRAC to verify the memory reports 6400 MT/s and CL52 timings for all 16 modules.

Does the 16-module kit include only the 128GB DDR5 RDIMMs, or are any tools or cables supplied?

The package contains exactly 16 x 128GB DDR5 6400MHz CL52 4Rx4 ECC RDIMMs; no tools, cables or additional hardware are included.
