64 GB DDR4 ECC RDIMM for PowerEdge R6515

This 64 GB DDR4 3200 module is built for the Dell PowerEdge R6515 server platform. It delivers registered ECC reliability for mission-critical workloads and virtualised environments. The single-stick layout lets administrators add capacity one slot at a time without disturbing existing banks.

Registered design runs at 1.2 V with CL22 latency

The registered buffer reduces electrical load on the memory controller, keeping power draw low at the standard 1.2 V operating voltage. CL22 timing at 3200 MT/s provides stable throughput for database and virtualisation tasks. No heat spreader is fitted, so airflow through the server chassis handles cooling directly.

288-pin RDIMM fits Dell-qualified slots only

The 288-pin form factor matches the R6515 memory sockets and the 2Rx4 organisation aligns with Dell's validated population rules. Builders must confirm the server's maximum supported capacity per slot and total system limit before installation. This module does not suit consumer desktop boards or platforms that require unbuffered memory.

Questions about this item

How do I install this 288-Pin DDR4 RDIMM in the Dell PowerEdge R6515, and what step is often missed?

Power off the server, open the chassis, align the notch on the 288-Pin DDR4 RDIMM with the slot key, press firmly until the ejector tabs click, then verify the module appears at 3200 MT/s in the BIOS memory configuration.

What maintenance or replacement will this 64GB ECC Registered module need over its service life?

No scheduled maintenance is required; the module has no heat spreader and operates at 1.20V, so only replace it if the system logs correctable ECC errors that exceed the platform threshold.

What limit appears first when this CL22 2Rx4 module runs sustained workloads on the R6515?

The CAS latency of 22 cycles at 3200 MT/s sets the baseline response time; under continuous load the memory controller will hit its thermal or bandwidth ceiling before the module itself throttles.
