768GB DDR5 RDIMM kit for PowerEdge R6615

This NEMIX RAM kit delivers 768GB of DDR5 5600 registered ECC memory across twelve 64GB modules. It is built for the Dell PowerEdge R6615 rack server and targets IT teams running virtualization, databases or AI workloads that demand high capacity with error correction.

Tool-free DIMM installation with population rules

The 288-pin RDIMMs slot into the server's memory channels without tools, and the kit ships as a matched 12-piece set. Installers must follow the R6615 population guide — mixing ranks or filling slots in the wrong order will prevent the system from posting.

Suited for Dell R6615 capacity max-out.

This configuration suits administrators who need the full 768GB supported by the R6615 and want a single validated kit. Buyers with different servers, workstations or consumer motherboards cannot use these registered ECC modules.

Questions about this item

How can I confirm the kit is running at 5600 MT/s with CL46 after installing it in my PowerEdge R6615?

Enter the system BIOS or use a tool such as CPU-Z to verify the memory frequency shows 5600 MT/s and the CAS latency reads 46.

What does the package contain and do I need any extra parts for the R6615?

The box includes twelve 64 GB DDR5 5600 CL46 ECC registered DIMMs for a total of 768 GB; no additional modules or accessories are required for the R6615.

Why choose the 12 × 64 GB kit instead of a smaller capacity for the R6615?

The 768 GB kit fills all twelve DIMM slots with 2Rx4 modules, delivering maximum supported capacity and bandwidth for memory-intensive workloads.
