Server memory for ECC workloads

The HPE P64706-B21 is a 32GB DDR5 module built for server platforms that require registered ECC memory. It operates at 5600 MHz with CL46 latency and a dual-rank 2Rx8 organisation. The 288-pin DIMM runs at 1.10 V and is suited to environments where data integrity and sustained throughput matter.

Thermal and power profile

Registered DDR5 modules at this speed and voltage draw modest power under typical server loads while the register helps reduce electrical loading on the memory bus. Standard server airflow across the DIMM slots keeps temperatures within spec without additional cooling. ECC operation adds minimal overhead and does not increase acoustic output.

SmartMemory firmware benefits

HPE SmartMemory firmware enables the module to report health, temperature and configuration data to the server management controller. This telemetry allows predictive failure alerts and simplifies inventory tracking across large deployments. The registered design and ECC function are unchanged; the firmware layer adds visibility without altering electrical behaviour.

Questions about this item

How do I install the 288-pin DIMM, and what step is most often missed?

Align the notch on the 288-pin DIMM with the slot key, press straight down until both side clips snap shut, then verify the module is fully seated by checking the clips are locked on both ends.

What maintenance or replacement will the dual-rank module need later?

No routine maintenance is required; if a memory error occurs, replace the 32GB module with an identical DDR5 5600 ECC Registered DIMM.

At what point does the CL46 latency become the limiting factor under sustained use?

CL46 is the fixed CAS latency of the DDR5 5600 module; it sets the minimum access delay for every read cycle regardless of workload duration.
