16GB DDR4 ECC UDIMM Server Memory

This 16 GB DDR4 2400 module provides error-correcting code memory for compatible server and workstation systems. It operates at PC4-19200 speed with CL17 latency and 1.20 V standard voltage. The unbuffered 2Rx8 design uses major brand chips and serves as a compatible replacement for the Kingston KSM24ED8/16ME part number.

Simple DIMM Installation Process

Installation follows the standard 288-pin DDR4 DIMM procedure: power down the system, open the chassis, align the module key notch with the slot, and press firmly until the retention clips engage. The most common issue is purchasing unbuffered ECC UDIMM modules for a platform that requires registered or load-reduced DIMMs, which prevents the system from posting.

Verify Platform Memory Requirements

Before ordering, confirm that your motherboard or server platform supports DDR4 2400 unbuffered ECC UDIMM modules in a 2Rx8 configuration. Check the qualified vendor list or manual for maximum capacity per slot and total system capacity limits. Ensure the system does not require registered or load-reduced memory types, as this unbuffered module will not function in those environments.

Questions about this item

How do I verify the module is running at 2400 MHz with CL17 after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 2400 MHz and CAS latency shows 17.

Does the package include only the single 16 GB DIMM or any extra parts?

The box contains one 16 GB DDR4 ECC UDIMM module; no brackets, cables or additional components are supplied.

Should I choose the 2Rx8 version or a different rank for my server?

Select this 2Rx8 module when your platform requires a dual-rank unbuffered ECC DIMM at 2400 MHz.
