HP-compatible 16 GB DDR4 server module

This Brute Networks registered DIMM delivers 16 GB of DDR4-2133 memory with CL15 timing at 1.2 V. It is built for HP servers that require ECC registered modules matching part number 726719-B21. The 2Rx4 organisation and major-brand DRAM chips target administrators extending the life of existing infrastructure.

Verify registered ECC support and slot count

Before ordering, confirm the host server accepts 288-pin registered DDR4 RDIMMs with ECC and that enough free slots remain for the desired capacity. Check the system documentation for maximum per-slot and total memory limits, as well as any population rules for 2Rx4 modules. Matching voltage at 1.2 V is also required.

Matched modules simplify multi-slot upgrades

Brute Networks supplies identically matched modules so every stick in an order carries the same DRAM vendor and revision. This removes the risk of mixed ranks or timings that can cause instability in multi-channel server configurations. The lifetime warranty covers the modules for as long as they remain in service.

Questions about this item

Does the 288-pin DDR4 RDIMM arrive alone or with any extra brackets or cables?

The module ships as a single 288-pin registered DIMM; no brackets, cables or additional hardware are included.

Should I pick the 2Rx4 16 GB stick or a different rank for my HP server?

This 2Rx4 16 GB registered DIMM matches HP part 726719-B21 and is validated for the same slots that require that rank configuration.

Will the CL15 2133 MT/s rating hold once the stick is seated in a live HP system?

The module is tested at 2133 MT/s CL15 1.20 V and meets the OEM specification for the HP platforms that list part 726719-B21.
