Dell PowerEdge R6415 R7415 R7425 XR2 upgrade

This 32GB DDR4 2666MHz ECC RDIMM is built for Dell PowerEdge R6415, R7415, R7425 and XR2 servers. It delivers registered error-correcting memory for workloads that require data integrity. The module runs at 1.2V with CL19 latency and a 2Rx4 organisation.

Registered ECC changes compatibility

Registered ECC memory works only in server and workstation platforms that support the buffered interface. It will not function in standard desktop computers and cannot be mixed with unbuffered modules. The 288-pin RDIMM form factor fits the qualified Dell systems directly.

32GB per module scales capacity

A single 32GB stick adds substantial headroom for virtualisation, databases and multi-user workloads. The DDR4 2666 speed is backward compatible with 2133MHz and 2400MHz operation. Systems needing more than the installed slot count allows will require additional modules.

Questions about this item

Will the 2Rx4 registered ECC DIMM need any firmware updates or periodic replacement in a Dell PowerEdge R7425?

The module is a standard JEDEC DDR4 2666 CL19 1.2 V registered ECC DIMM; no firmware is required and it has no scheduled replacement interval.

What limits sustained throughput first — the CL19 latency or the 2666 MT/s data rate?

The 2666 MT/s data rate is the ceiling; CL19 latency determines access delay but does not cap maximum bandwidth.

How much heat and power does a 32 GB 1.2 V registered DIMM add when the server runs 24/7?

At 1.2 V the module draws only a few watts and has no heat spreader, so it adds minimal heat to the chassis airflow.
