32 GB DDR4 ECC RDIMM for HPE servers

This registered DIMM adds 32 GB of DDR4 3200 memory to compatible HPE servers and workstations. It carries ECC and registered buffering for data integrity in multi-socket platforms. The module uses 2Rx4 organisation and runs at 1.20 V. It is built for IT teams expanding memory capacity in qualified HPE systems.

Thermals and power at 1.20 V

Operating at the standard DDR4 voltage of 1.20 V keeps power draw low in dense server chassis. The module has no heat spreader, relying on system airflow for cooling. Registered buffering reduces electrical load on the memory controller. Acoustic impact is negligible because the DIMM adds no moving parts.

Single rank constraint is 2Rx4

The 2Rx4 rank configuration determines whether the memory controller can address the full 32 GB per slot. Systems limited to single-rank or 1Rx4 modules will not support this DIMM. Verify the platform’s qualified vendor list for 2Rx4 compatibility before purchase.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in my HPE server, and what step is often missed?

Power down the server, open the chassis, align the module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the 32 GB module is detected at 3200 MT/s.

What maintenance or replacement will this ECC registered module need over time?

The module itself has no user-serviceable parts; monitor system logs for corrected ECC errors, and replace the DIMM if uncorrectable errors appear or if capacity expansion requires additional 2Rx4 ranks.

What limit appears first when this CL22 1.2 V module runs sustained workloads?

The CAS latency of 22 cycles at 3200 MT/s sets the baseline response time; under continuous load the memory controller’s thermal throttling or rank interleaving limits will be reached before the DRAM voltage or frequency limits.
