32GB DDR4-3200 ECC Registered DIMM

This single 32GB module delivers DDR4-3200 performance with CL22 latency and ECC protection. Registered signal processing helps maintain stability in multi-module server configurations. The 288-pin DIMM form factor fits standard server memory slots. It suits administrators expanding memory capacity in compatible HPE ProLiant or similar enterprise platforms.

Thermals and power at 1.20 V

Operating at 1.20 V, the module runs within standard DDR4 voltage limits for reduced power draw. Lower voltage contributes to cooler operation inside dense chassis. Registered buffering adds minimal overhead while improving signal integrity across full DIMM populations. No active cooling is required beyond normal server airflow.

Registered ECC for data integrity

The registered ECC design detects and corrects single-bit errors while reducing electrical load on the memory controller. This enables reliable operation when populating multiple slots per channel. Dual-rank organisation balances capacity and rank density for typical server workloads. The module ships ready for installation without additional software or firmware.

Questions about this item

How do I install the 288-pin DDR4 module and what step is often missed?

Align the notch on the module with the slot key, press firmly until both side clips click, then verify the server BIOS recognises the full 32GB at 3200MHz.

What maintenance or replacement will the 32GB ECC registered DIMM need later?

No routine maintenance is required; replace only if the server reports correctable ECC errors or a DIMM failure alert.

What limit appears first on this CL22 3200MHz module under sustained load?

The CL22 latency and 1.20V operation set the timing and thermal ceiling before bandwidth saturates.
