HP Compatible 32GB DDR4 RDIMM

This Brute Networks module delivers 32GB of DDR4 2133 registered memory for HP server upgrades. It operates at 1.2V with CL15 latency and uses a 2Rx4 organisation on a 288-pin form factor. The part carries the 728629-B21-BN designation and is built with major-brand DRAM chips. It is validated for full compatibility with the original OEM specification.

Who this suits and who it does not

It fits administrators expanding capacity in HP systems that require registered ECC DDR4 at this speed and rank configuration. The 2Rx4 layout supports high-density population in compatible slots. Builders needing unbuffered UDIMM modules, different voltages, or higher DDR4 data rates must select alternative parts. Systems limited to lower maximum module capacities cannot accept this 32GB density.

Deciding specification: 2Rx4 registered ECC

The registered 2Rx4 ECC design is the single attribute that determines whether this module works in a given HP server. Only platforms qualified for registered DDR4 with this rank structure and voltage will post correctly. Verify the server memory qualified-vendor list for 728629-B21 equivalence before purchase.

Questions about this item

What does the 2133 MHz speed mean for actual server throughput?

The module runs at 2133 MT/s, delivering up to 17000 MB/s peak bandwidth per DIMM when the memory controller operates at the rated DDR4-2133 data rate.

How does the registered DDR4 interface affect maximum capacity per channel?

Registered buffering reduces electrical load on the memory bus, allowing more DIMMs per channel than unbuffered modules while maintaining signal integrity at 2133 MT/s.

Will this 288-pin RDIMM fit a standard DDR4 server slot?

Yes, the 288-pin DDR4 RDIMM form factor matches the industry-standard slot used in compatible HP servers; the module is keyed for 1.2 V operation.
