16GB DDR4-2400 RDIMM server memory operating at 1.2V with 2400MHz speed

  • 16 GB DDR4-2400 RDIMM expands server memory capacity
  • 2400 MHz data rate accelerates data-intensive application loads
  • 2 V operation lowers power draw versus DDR3
  • Up to 30 % single-DIMM performance gain over DDR3
  • 04 lb lightweight module simplifies dense chassis installation

What this memory is

This is a 16GB DDR4-2400 RDIMM built for HPE servers. Registered buffering adds signal integrity for multi-DIMM channels. The module runs at 1.2 V and is sold new for replacement or capacity upgrades in supported systems.

The specification that decides fit

Speed is 2400 MHz rated as PC4-19200. The registered design and DDR4 voltage must match the platform memory controller. Verify the server qualified-vendor list before purchase because unlisted RDIMMs can fail to initialise.

Installation and common issues

The DIMM weighs 0.04 lbs and keys into standard DDR4 slots. Handle by the edges to avoid contaminating the gold contacts. The most frequent problem is mixing registered and unbuffered modules or exceeding the channel population limit defined by the system board.

Questions about this item

How does 2400 MHz speed translate to real-world responsiveness?

The DDR4-2400 module runs at 1.2 V and delivers up to 30% faster single-DIMM performance and 65% faster throughput in 3-DIMM-per-channel workloads over DDR3.

What does the PC4-19200 rating cap in practice?

PC4-19200 sets a peak bandwidth ceiling of 19 200 MB/s; actual throughput depends on the server's memory controller and channel population.

Will this RDIMM fit a standard server DIMM slot?

Yes, it is a registered DDR4 DIMM weighing 0.04 lbs and designed for compatible server memory slots.
