Dell PowerEdge R6515 64GB DDR4 module

This NEMIX RAM module delivers 64GB of DDR4 3200 registered ECC memory in a single 288-pin RDIMM. It operates at 1.2V with CL22 latency and a 2Rx4 organisation using major OEM DRAM chips. The part is validated for the Dell PowerEdge R6515 rack server.

IT teams upgrading Dell PowerEdge R6515 servers

This module suits administrators who need to expand memory capacity in a validated Dell PowerEdge R6515 configuration. It is not for desktop PCs, workstations or non-Dell platforms that require unbuffered DIMMs or different registered timings. Buyers needing lower-capacity sticks or non-ECC memory should look elsewhere.

Single-slot registered ECC upgrade for R6515

The RDIMM plugs directly into an available DDR4 slot on the PowerEdge R6515 motherboard and draws 1.2V from the server power budget. Registered buffering reduces electrical load on the memory controller, freeing headroom for additional modules. ECC protection corrects single-bit errors to maintain data integrity under sustained workloads.

Questions about this item

Does this 64GB DDR4 3200 ECC RDIMM require a Dell PowerEdge R6515 server to function?

Yes, this module is built for the Dell PowerEdge R6515 and needs that platform's registered ECC memory architecture to operate.

Can I mix this CL22 2Rx4 registered DIMM with older unbuffered DDR4 sticks I already have?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC modules; the memory controller requires uniform registered signalling across all populated slots.

How do I confirm the 3200 MT/s speed and ECC are active after installing the 288-pin module?

Enter the system BIOS or iDRAC interface; both will report the module running at 3200 MT/s with ECC enabled and the correct 2Rx4 organisation.
