16GB DDR4 2133 ECC RDIMM for IBM-Lenovo

This 16GB DDR4 2133 ECC RDIMM module replaces IBM-Lenovo part numbers 95Y4820 and 95Y4823. It is built for server and workstation systems that require registered memory with error correction. The single 288-pin DIMM runs at 1.2V with a CAS latency of 15.

Installation requires matching registered DIMM slots

The module fits standard 288-pin DDR4 DIMM sockets. Because it is a registered ECC RDIMM, the platform must support registered memory and ECC; consumer desktop boards that accept only unbuffered non-ECC modules will not work. Verify the system memory specifications before purchase to avoid a mismatch.

Sustained workloads benefit from error correction

Under continuous load the ECC function detects and corrects single-bit errors, helping maintain data integrity in long-running server tasks. The 2Rx4 organisation and major-brand chips deliver stable throughput at the rated 2133 MT/s speed without the voltage increase that higher-frequency modules demand.

Points forts

  • 16 GB capacity expands server memory headroom for larger workloads
  • DDR4 2133 MHz speed delivers PC4-17000 bandwidth for responsive data access
  • ECC RDIMM registered design corrects single-bit errors to protect data integrity
  • 2Rx4 dual-rank organisation increases memory density per DIMM slot
  • 2 V DDR4 standard voltage reduces power draw compared to previous DDR generations

Questions sur cet article

How do I verify the 16GB DDR4 2133 ECC RDIMM is recognised at full speed after installation?

Check the BIOS or UEFI memory information screen to confirm the module shows 16GB at 2133MHz with ECC and registered status, then run a memory diagnostic to validate stability.

What comes with the 16GB DDR4 2133 ECC RDIMM and what must be sourced separately?

The package contains one 16GB DDR4 2133 PC4-17000 ECC RDIMM 2Rx4 288-pin module; no cables, brackets or additional DIMMs are included.

Which capacity and rank should I choose between the 16GB 2Rx4 ECC RDIMM and other listed versions?

Select this 16GB 2Rx4 ECC RDIMM when your IBM-Lenovo 95Y4820 or 95Y4823 server requires a single registered DDR4 2133 module at 1.2V with major-brand chips.
