64GB DDR4 2933 ECC RDIMM for servers

This 64GB A-Tech module runs at DDR4 2933 (PC4-23400) with CL21 latency and 1.20V operation. It is a registered ECC DIMM built with 2Rx4 organisation on a 288-pin form factor. The stick uses major-brand chips and is validated as a direct replacement for HP part numbers P03053-091, P03053-0A1, P03053-CA1, P06192-001, P14492-B21 and P28217-B21.

Suited for registered ECC platforms only

This module fits servers and workstations that require registered ECC DDR4 memory at the 2933 speed grade. It will not work in consumer desktop boards that accept only unbuffered non-ECC DIMMs. Buyers needing unbuffered memory or a different speed bin should look at other modules.

288-pin DDR4 DIMM form factor

The single physical specification that decides compatibility is the 288-pin DDR4 DIMM form factor combined with registered ECC signalling. Verify that your system’s memory slots and BIOS support registered ECC DDR4 before ordering.

Questions about this item

Does this 64GB module use the standard 288-pin DDR4 DIMM form factor?

Yes, it is a 288-pin DDR4 DIMM that fits any server or workstation slot built for registered DDR4 memory.

What is the correct way to seat this registered ECC module so the system recognises the full 64GB?

Align the notch with the slot key, press down evenly until both side clips click, and populate slots in the order your motherboard manual specifies for registered DIMMs.

When should I expect to replace this 2933MHz ECC RDIMM in a typical server workload?

ECC RDIMMs have no moving parts; they are replaced only if a memory test reports uncorrectable errors or a capacity upgrade is required.
