HPE-Compatible DDR4 RDIMM

This 8 GB registered DDR4 module runs at 3200 MT/s with CL22 latency and 1.2 V operation. It uses a 1Rx8 organisation and 288-pin form factor for HPE server and workstation platforms. ECC and registered buffering support data integrity in multi-socket configurations.

Registered ECC limits

Registered DIMMs add a clock cycle of buffering that reduces electrical load on the memory controller but prevents use in consumer desktop boards that expect unbuffered modules. ECC function requires a platform that exposes the extra parity bits; otherwise the module operates as non-ECC. DDR4 3200 speed is only realised when the system memory controller and BIOS support the PC4-25600 data rate.

Build and daily handling

The module has no heat spreader, so airflow across the PCB is the only cooling path in dense chassis. Samsung, Micron or Hynix DRAM chips are used depending on supply, all qualified to the same JEDEC standard. A lifetime replacement warranty backs the part, and the single-rank layout leaves additional slots open for future capacity expansion.

Questions about this item

Should I choose the 8 GB single module or look for a larger capacity kit?

This listing is an 8 GB (1×8 GB) DDR4 3200 RDIMM. If your HPE server has free slots and the memory controller supports the density, you can add multiple identical modules to reach the total capacity you need.

What does the 3200 MT/s rating deliver in an actual HPE server?

The module runs at DDR4 3200 (PC4 25600) with CL22 latency. In a compatible HPE platform it will operate at the rated 3200 MT/s, providing the bandwidth and error-correction the system expects for registered ECC workloads.

Does the 288-pin RDIMM interface limit the speed or features I can use?

The 288-pin DDR4 RDIMM form factor carries the registered ECC signals required by HPE server memory controllers. It supports the full DDR4 3200 data rate and ECC functionality defined for this module; no additional features are enabled or restricted by the connector itself.
