16GB DDR4 ECC LRDIMM for Servers

This 16GB DDR4 module operates at 2133MHz with CL15 latency and 1.20V voltage. It uses a Load Reduced DIMM design with 2Rx4 organisation and major-brand chips. The 288-pin form factor fits server and workstation boards that require registered ECC memory.

Load Reduced DIMM limits electrical load

LRDIMM technology buffers both data and address signals, allowing higher capacities per channel than standard RDIMMs. The module runs at the DDR4 2133 standard (PC4-17000) with ECC error correction. Systems must support the LRDIMM protocol; standard RDIMM-only platforms will not recognise it.

ECC LRDIMM protocol decides compatibility

The single specification that determines fit is whether the motherboard and CPU memory controller explicitly support DDR4 ECC Load Reduced DIMMs. Buyers who need standard RDIMM or non-ECC UDIMM modules cannot use this part. Verify the system qualified-vendor list before purchase.

Questions about this item

Should I pick a single 16GB module or combine several to reach my target capacity?

This listing is a single 16GB module; add more identical modules to scale capacity in 16GB increments.

What does the 2133MHz rating actually deliver inside a server?

It runs at DDR4 2133 MT/s, providing PC4-17000 peak bandwidth with CL15 latency at 1.2V.

How does the ECC LRDIMM 2Rx4 design affect my platform?

Load Reduced DIMM with 2Rx4 organisation reduces electrical load on the memory bus, allowing higher densities per channel.
