A-Tech 16GB DDR4 2133MHz ECC UDIMM CL15 2Rx8 1.20V 288-Pin Server Memory

16GB DDR4 ECC UDIMM for servers

This A-Tech module delivers 16GB of DDR4 2133MHz memory with ECC error correction and CL15 latency. It operates at the standard 1.20V and uses a 2Rx8 unbuffered design. The 288-pin DIMM is built as a compatible replacement for Kingston KTD-PE421E/16G and KVR21E15D8/16I modules. It targets administrators upgrading or repairing server and workstation platforms that require ECC unbuffered memory.

Replaces Kingston KTD-PE421E/16G and KVR21E15D8/16I

The module matches the 16GB capacity, 2133MHz speed, CL15 timing and 1.20V voltage of those Kingston parts. It serves as a direct substitute when original modules are discontinued or when expanding capacity within the same specification. The jump is worthwhile when your system reports correctable memory errors or when workloads exceed the current installed memory limit.

Simple DIMM installation with compatibility checks

Installation follows standard UDIMM procedure: power down, open the chassis, align the 288-pin edge connector with the slot, and press until the retention clips engage. What usually goes wrong is a mismatch between registered and unbuffered memory types or exceeding the platform's maximum supported speed per channel. Verify that your motherboard accepts unbuffered ECC DDR4 before ordering.
