32GB DDR4 ECC LRDIMM for HP servers

This 32GB DDR4 2133 ECC LRDIMM module is built for HP ProLiant and Apollo servers that require load-reduced registered memory. It suits administrators upgrading or repairing systems using part numbers such as 726722-B21, 752372-081, 752372-581, 774174-001, 790110-001, 839985-S21 or J9P84AA. The single 288-pin DIMM installs in a standard DDR4 server slot and operates at 1.20V.

Capacity headroom at 32GB per module

A single 32GB 4Rx4 module provides substantial capacity for virtualisation hosts, database nodes or compute clusters that benefit from high-density memory. The load-reduced architecture lowers electrical load on the memory bus, allowing larger configurations than standard RDIMMs. Systems limited to lower-density RDIMMs or fewer DIMM slots will not reach the same total capacity with this module.

Major-brand chips and lifetime support

The module uses major-brand DRAM chips and undergoes A-Tech quality-assurance testing for dependable operation. Buyers receive US-based technical support before, during and after purchase, plus a lifetime warranty on the module itself. No additional software, cables or cooling accessories are included in the package.

Questions about this item

Will this 4Rx4 LRDIMM run with my existing 2Rx4 registered DIMMs in the same HP server?

LRDIMMs and registered DIMMs cannot be mixed in the same channel; the server will not boot if both types are populated together.

How can I confirm the module is running at DDR4 2133 CL15 with ECC active after installation?

Check the BIOS memory information or run a tool such as dmidecode; it should report 2133 MT/s, CAS 15, 1.20 V and ECC enabled.

Does the package include only the single 32 GB 288-pin module or are heat spreaders or cables also supplied?

Only the 32 GB DDR4 2133 ECC LRDIMM module is included; no heat spreader, cables or additional hardware are provided.
