Compatible Lenovo Server RDIMM

This 16 GB registered DDR4 module is built to Lenovo part number 4X70G78062 and runs at 2133 MT/s with CL15 latency. It uses a 2Rx4 organisation and operates at 1.20 V, matching the original OEM specification for supported Lenovo servers.

Suited for registered memory slots only

The module fits systems that accept 288-pin registered ECC DDR4 RDIMMs. It will not work in platforms that require unbuffered UDIMMs or load-reduced LRDIMMs, and it cannot be used in laptops or desktops that take SO-DIMMs.

Registered ECC with 2Rx4 layout

The single decisive specification is the registered ECC 2Rx4 configuration at DDR4-2133; only motherboards qualified for this exact register and rank arrangement will post reliably with this module.

Questions about this item

What server platform must I already own to use this 288-Pin DDR4-2133 Registered RDIMM?

The module is validated for Lenovo servers that accept 1.20 V DDR4-2133 PC4-17000 registered ECC memory with a 2Rx4 organisation.

Can I keep my existing DDR4-2133 CL15 registered DIMMs and add this 16 GB stick without changing BIOS settings?

Yes — the stick runs at the same 2133 MT/s speed, CL15 latency and 1.20 V voltage, so it will operate alongside identical-spec modules at the platform's default JEDEC profile.

How do I confirm the module is running at 2133 MT/s with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode / lshw; they should report 2133 MT/s, CL15, 1.20 V, registered and ECC enabled for the new DIMM.
