Dell PowerEdge R7515 upgrade

This 64GB DDR4 3200 ECC RDIMM is built for the Dell PowerEdge R7515 rack server. It adds registered, error-correcting memory to support virtualisation, databases and other enterprise workloads. The module runs at 1.2V with a CL22 latency and uses a 2Rx4 organisation. It is sold as a single stick for targeted capacity increases.

288-pin registered DDR4 slot

The DIMM fits a standard 288-pin DDR4 RDIMM slot and requires a platform that accepts registered ECC memory. No heat spreader is fitted, so airflow in the server chassis cools the chips directly. Adding this module frees non-ECC slots for other uses and keeps the memory subsystem on a single voltage rail.

IT teams scaling a R7515

Administrators expanding a PowerEdge R7515 with validated ECC RDIMMs will find this part matches the server’s qualified vendor list. Sites that need unbuffered UDIMMs, lower capacities or consumer DDR4 speeds should select a different module type.

Questions about this item

Does the CL22 latency become a bottleneck during sustained heavy workloads on the Dell PowerEdge R7515?

CL22 is the rated CAS latency for this DDR4 3200 module; actual bottleneck depends on the server workload and memory controller configuration.

How much heat and power does a single 64GB 1.20V module produce when running continuously in the R7515?

The module operates at 1.20V standard DDR4 voltage; registered ECC design distributes load across ranks, but exact thermal output varies with chassis airflow and total DIMM population.

What specific Dell PowerEdge R7515 firmware or BIOS version is required before installing this 2Rx4 RDIMM?

Compatibility is validated for the Dell PowerEdge R7515 platform; consult the Dell system documentation for minimum BIOS revision supporting 64GB 2Rx4 DDR4 3200 RDIMMs.
