16 GB DDR4-2400 Registered RDIMM

This 16 GB DDR4 module runs at 2400 MT/s with a CL15 latency and operates at 1.20 V. It uses a 288-pin registered design with ECC and a 2Rx4 rank configuration built on major-brand components. The part is fully compatible with HP systems that specify the 809082-091 part number.

Server upgrades needing HP 809082-091 equivalence

This module suits administrators replacing or expanding memory in HP servers that require registered ECC DDR4 at this speed and rank. It is not for desktop PCs or laptops that accept only unbuffered non-ECC DIMMs. Buyers who need higher capacities per slot or faster DDR4 speeds should look at other modules.

Registered ECC with 2Rx4 organisation

The registered buffer and ECC functionality are the decisive specifications; they determine whether the motherboard can initialise the module and maintain data integrity. Systems that require unbuffered memory or a different rank layout will not accept this DIMM.

Questions about this item

Should I choose the 16GB 2Rx4 module or a single-rank alternative?

The 2Rx4 organisation gives two ranks per module, which can improve throughput on servers that support multi-rank interleaving; single-rank DIMMs may limit maximum capacity per channel.

What does the PC4-19200 rating mean once the DIMM is installed?

PC4-19200 indicates a peak transfer rate of 19200 MB/s at DDR4-2400; actual throughput depends on the memory controller and channel population.

How does the registered DDR4-2400 interface affect maximum speed in my server?

The registered 288-pin DDR4 interface runs at 2400 MT/s; the memory controller and BIOS determine the final operating frequency, which may be lower if multiple DIMMs populate a channel.
