HP-compatible 32GB DDR4-3200 ECC RDIMM

This registered DIMM delivers 32GB of DDR4 memory at 3200MHz with ECC protection. It matches HP part number P56429-B21 and is built for servers that require registered, dual-rank modules. The 2Rx4 organisation supports higher densities per channel.

Major-brand chipset on a standard RDIMM PCB

The module uses a major-brand chipset and the industry-standard 288-pin RDIMM form factor. Registered buffering reduces electrical load on the memory controller, allowing larger total capacities in multi-slot servers. Installation follows normal DIMM seating procedure with the key notch aligned.

1.20V operation keeps power draw low

At 1.20V the module runs at standard DDR4 voltage, limiting heat output in densely populated chassis. ECC circuitry corrects single-bit errors without adding measurable latency. The registered design helps maintain signal integrity across full memory arrays under sustained workloads.

Questions about this item

Does the DDR4-3200 interface limit real-world throughput to the PC4-25600 rating?

The module runs at 3200 MT/s, giving a peak transfer rate of 25600 MB/s; actual throughput depends on the server's memory controller and channel population.

What physical slot and form factor does this 32GB registered DIMM require?

It fits a standard 288-pin DDR4 RDIMM socket; the 2Rx4 organisation and registered buffer mean the motherboard must support registered ECC memory.

How is the module installed, and what step is often missed?

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