HP-compatible registered DDR4 for servers

This 32GB DDR4 module is built for HP servers that require registered ECC memory. It suits administrators expanding capacity in supported platforms without mixing vendors.

32GB capacity at DDR4-2400 CL15

The module delivers 32GB per DIMM at PC4-19200 speed with CAS latency 15 and 1.20V operation. Dual-rank 2Rx4 organisation provides density for multi-socket configurations where registered buffers are mandatory.

288-pin RDIMM with major-brand components

Each stick uses Samsung, SK Hynix or Micron ICs and matches HP part 805351-B21 for validated compatibility. Registered design and ECC support maintain signal integrity in dense memory arrays.

Questions about this item

Will this 32GB DDR4 2400 CL15 Registered 2Rx4 module work alongside my existing DDR4 2400 RDIMMs in the same server?

Mixing modules of different capacities or ranks is possible on many platforms, but the server's memory controller and BIOS determine whether mixed configurations run at the rated 2400 MT/s or fall back to a lower speed; consult the system vendor's qualified vendor list for the exact part number 805351-B21.

How can I verify the module is running at 2400 MT/s with CL15 timings after installation?

Enter the server BIOS or use a tool such as CPU-Z to confirm the memory frequency reads 2400 MT/s and the CAS latency shows 15 cycles; registered ECC modules also report status via the system management interface.

Does the box contain only the 32GB RDIMM or are any cables or brackets included?

The package contains the 32GB 288-pin DDR4 RDIMM only; no cables, brackets or additional hardware are supplied.
