16GB DDR4 2400 ECC RDIMM for servers

This 16GB registered DIMM brings error-correcting DDR4 memory to HP server and workstation platforms that require 2400 MHz PC4-19200 modules. The single-rank 2Rx8 organisation and 1.20V operation match the original HP part numbers listed for direct replacement. System administrators expanding memory capacity in compatible HP ProLiant or Apollo systems will find the specifications aligned with OEM requirements.

Upgrading from smaller or non-ECC modules

Replacing lower-capacity RDIMMs or unbuffered ECC UDIMMs with this 16GB registered module increases total addressable memory while preserving the error-correction and signal-integrity features the platform expects. The jump is worth it when workloads exceed the current memory ceiling or when the system reports correctable errors that point to aging modules. Builders who need higher densities per slot or faster data rates must verify platform support before ordering.

Practical limits of DDR4 2400 RDIMM

The DDR4 2400 interface caps theoretical bandwidth at PC4-19200, so throughput scales with channel count rather than module speed. Registered buffering adds one clock cycle of latency, which is standard for multi-module server configurations but unnecessary for single-DIMM desktop boards. Mixing speeds forces all channels to the slowest installed module, so uniform population is required to maintain the rated 2400 MHz operation.

商品問答

Does the 288-pin DDR4 DIMM fit my HP server's registered memory slots?

The module uses the standard 288-pin DDR4 RDIMM form factor and matches the HP part numbers listed, so it installs in any compatible HP server slot that accepts registered ECC memory.

What is the correct way to seat this registered ECC module, and what step do people often miss?

Align the notch with the slot key, press firmly until both retention clips click, and verify the system recognises the full 16 GB at 2400 MHz in BIOS — skipping the BIOS check is the common oversight.

Will the ECC RDIMM chips or the 1.20 V voltage regulation need replacement after a few years?

No scheduled maintenance is required; the major-brand chips and standard DDR4 voltage are rated for continuous server operation for the life of the system.
