  • DDR4 2133 speed delivers reliable bandwidth
  • 2Rx8 dual-rank organisation optimises memory density

Server memory for error-correcting workloads

This 16 GB DDR4 module runs at 2133 MT/s with ECC protection. The 288-pin unbuffered design fits server boards that accept UDIMMs. It is built for systems where data integrity matters more than raw bandwidth.

Suits servers needing ECC UDIMMs

Administrators who require registered DIMMs or load-reduced modules cannot use this stick. Builders working with consumer desktop boards that lack ECC support in the BIOS should look elsewhere. The single 16 GB capacity also limits maximum density per channel.

The deciding spec is unbuffered ECC

Only platforms wired for UDIMM ECC will initialise this memory correctly. Registered or fully buffered channels will not recognise the module. Verify the motherboard manual for UDIMM ECC support before ordering.

Questions about this item

Does the 16 GB DDR4 2133 ECC unbuffered module require any periodic maintenance or component replacement during its service life?

No maintenance or replacement is required for the memory module itself; it is a solid-state component with no moving parts or consumable elements.

What limit appears first when the 2Rx8 16 GB stick runs at DDR4 2133 continuously under full load?

The thermal envelope of the unbuffered DDR4 2133 ICs is the first constraint; sustained write/read streams will hit temperature limits before signal-integrity or rank-interleaving bottlenecks appear.

How much noise, heat and power does the 16 GB 288-pin DDR4 2133 module generate during all-day operation?

The module is silent, draws only the standard DDR4 1.2 V supply current for a 16 GB 2Rx8 density, and its heat output stays within the normal DDR4 2133 thermal envelope for server workloads.
