32GB DDR4-3200 ECC RDIMM for servers

This 32GB DDR4-3200 registered DIMM provides ECC error correction for data integrity in server workloads. It operates at PC4-25600 speed with a 1Rx4 rank configuration and runs at 1.20V. The module is 100% HP compatible and matches part number P38454-H21 for validated deployments.

Fits registered ECC DDR4 slots in compatible servers

The RDIMM form factor requires a motherboard that supports registered, ECC DDR4 memory and cannot be used in standard unbuffered consumer platforms. Its single-rank 1Rx4 organisation leaves additional memory channels free for future capacity expansion within the same server. The 1.20V standard voltage simplifies power budgeting alongside other DDR4 modules.

Runs at standard DDR4 voltage with ECC overhead

At 1.20V the module draws typical DDR4 power while the on-die ECC logic adds minimal thermal load compared with non-ECC equivalents. Registered buffering reduces electrical loading on the memory controller, helping signal integrity at 3200 MT/s without requiring additional cooling beyond normal server airflow. The major-brand chipset ensures consistent thermal behaviour under sustained enterprise workloads.

Questions about this item

Will the 1.20V DDR4-3200 DIMM throttle first under sustained load?

The module runs at 1.20V and 3200 MT/s; thermal throttling depends on your chassis airflow and CPU cooler, not on the DIMM alone.

How much power does a 32GB 1Rx4 registered DIMM draw when the server runs all day?

Standard DDR4-3200 1Rx4 registered DIMMs typically draw 3–5 W each at 1.20V; exact figure varies by workload and motherboard VRM efficiency.

What motherboard slot and CPU memory controller are required for this P38454-H21 equivalent RDIMM to function?

You need a DDR4 RDIMM slot with ECC support and a CPU memory controller that accepts 1Rx4 registered modules at 3200 MT/s.
