16GB DDR4 2400 ECC RDIMM Server Module

This 16GB DDR4 2400 ECC RDIMM module uses a 288-pin DIMM form factor and operates at 1.2V with CL17 latency. It is built with major brand chips and registered architecture for stable server and workstation operation. The single 1Rx4 rank design fits compatible IBM-Lenovo systems requiring part 78P4889.

Who This Suits and Who It Does Not

This module suits administrators upgrading IBM-Lenovo servers that specifically require DDR4 2400 registered ECC memory in a 16GB density. It is not for buyers who need non-ECC unbuffered DIMMs, desktop SO-DIMMs, or capacities other than 16GB per module.

The Deciding Specification

Registered ECC DDR4 2400 with 1Rx4 organisation and 288-pin DIMM form factor is the single specification that determines compatibility. Only systems qualified for this exact registered ECC type and speed will accept the module.

Questions sur cet article

Will the ECC RDIMM registered buffer need replacement after extended server use?

The registered buffer is integrated into the DDR4 module and is not a separate replaceable part; the 16 GB stick carries a lifetime warranty.

What thermal or power limit appears first when the 1Rx4 module runs at 2400 MHz continuously?

The module operates at the standard DDR4 voltage of 1.20 V and CL17 latency, so power draw stays within the JEDEC spec for registered DIMMs under sustained load.

How much heat and noise does the 288-pin DIMM add to a server chassis running all day?

The DDR4 2400 RDIMM itself has no moving parts and draws 1.2 V, so it adds negligible heat and zero acoustic noise to the system.
