Capacity & Compatibility

This 64 GB DDR4 module is built for HPE servers and workstations that require load-reduced ECC memory. The single-stick configuration suits administrators expanding capacity in systems qualified for the P28219-B21 part number.

Thermals & Power

Operating at 1.2 V with a CL21 latency, the module draws minimal power for its density. No heat spreader is fitted, so airflow across the DIMM slots handles cooling in standard server chassis.

Build & Connectors

The 288-pin LRDIMM uses a 4Rx4 organisation with major OEM DRAM chips and undergoes load testing before shipment. Buyers needing registered DIMMs or non-ECC memory for consumer platforms cannot use this module.

Questions about this item

How do I install this 288-pin DDR4 LRDIMM and which slot-population rule do people miss?

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then check the HPE service guide for the required 4Rx4 population order because mixing ranks in the wrong channels prevents the system from posting.

What maintenance or replacement will this 64 GB ECC LRDIMM need during its service life?

No periodic maintenance is required; the module has no heat spreader or moving parts, so only a failed chip or a firmware update that changes the supported rank configuration would ever require replacement.

What limit appears first when this CL21 2933 MT/s module runs sustained heavy workloads?

The CAS latency of 21 cycles at 2933 MT/s sets the minimum access delay, so memory-controller throughput hits that timing ceiling before thermal or voltage limits become a factor.
