Key Features

128 GB memory capacity for high-density server configurations
DDR4-3200 transfer rate for supported memory channels
ECC operation for error-correcting server memory environments
Registered DIMM form factor for RDIMM-capable platforms
HP R4S29A compatibility alignment

Increase installed server memory capacity with a 128 GB DDR4-3200 ECC registered DIMM for compatible HP platforms. Registered DIMM architecture is used in server memory channels that support RDIMMs, while ECC memory adds error-correction capability for workloads where data integrity and stable operation matter. The module is specified at DDR4-3200 speed and is intended for systems that can operate a 128 GB ECC RDIMM at that rate. Axiom Memory R4S29A-AX corresponds to the HP R4S29A memory requirement named for this module. It fits deployments where an existing HP server has available memory capacity and its processor, firmware, memory configuration rules, and installed DIMM population support 128 GB DDR4 registered ECC modules. Match the server platform's supported DIMM type before installation; RDIMM and unbuffered DIMM memory are different electrical module classes. Within a DDR4 server-memory configuration, this module is distinguished by its 128 GB capacity, DDR4-3200 transfer rate, ECC support, and registered form factor. Those characteristics make it a specific option for increasing capacity without changing to another memory technology generation. Use the HP memory requirement and the server's supported-memory matrix to confirm channel population, maximum memory capacity, and supported operating speed for the intended configuration.

Ideal For

Expanding memory capacity in a compatible HP server running virtualization hosts with memory-intensive virtual machines.
Adding high-density ECC RDIMMs to an HP server used for databases, analytics, or in-memory application workloads.

Frequently Asked Questions

How do I confirm R4S29A-AX is the right part for my deployment?▾

Confirm that the HP server supports 128 GB DDR4-3200 ECC registered DIMMs and that its memory documentation lists compatibility with the HP R4S29A requirement. Also verify the server's maximum memory capacity, supported DIMM population rules, and processor-dependent memory speed.

What type of memory module is this?▾

This is a 128 GB DDR4-3200 ECC registered DIMM, commonly called an RDIMM. It is intended for server platforms with RDIMM-capable memory channels and should not be substituted for an unbuffered DIMM in systems that require registered memory.

Can this module run at a lower memory speed?▾

The module is specified as DDR4-3200 memory. Actual operating speed depends on the compatible server platform, installed processors, firmware, and overall DIMM population. Server memory controllers can apply a lower supported speed when configuration limits require it.

Why does ECC and RDIMM support matter for server memory?▾

ECC adds error-correction capability to memory operation, while RDIMM architecture is used by server platforms that need registered memory modules. Both characteristics must match the server's supported-memory requirements; a platform that requires RDIMMs cannot use ordinary desktop-class unbuffered DIMMs.
