16GB DDR4-2133 ECC UDIMM for desktop systems

This Axiom memory module provides 16GB of DDR4 capacity with ECC error correction for data integrity. It operates at 2133MHz with a CL15 latency and 1.2V voltage. The unbuffered DIMM uses a standard 288-pin layout.

Practical limits of the DDR4 interface

DDR4 bandwidth tops out at the rated transfer speed, so sustained throughput cannot exceed the 2133MT/s specification. The single-module density caps total capacity per slot at 16GB. ECC adds parity overhead that slightly reduces usable bandwidth compared to non-ECC equivalents. CL15 timing sets the minimum latency floor for random access patterns.

Questions about this item

Should I pick the 16 GB DDR4-2133 CL15 ECC module or a different capacity for my Lenovo desktop?

This specific module is 16 GB running at 2133 MHz with CL15 latency and ECC. Choose it when your Lenovo system requires that exact density and speed; otherwise select the capacity your board's qualified-vendor list recommends.

What does the 2133 MHz rating mean once the stick is installed?

The module will operate at 2133 MT/s (PC4-17000) at 1.2 V with CL15 timing. If the platform supports Intel XMP 2.0 the profile can be loaded automatically, otherwise it runs at the standard JEDEC DDR4-2133 speed.
