Capacity and form factor

This NEMIX RAM module provides 32GB of DDR4 memory in a single 288-pin RDIMM. It runs at 2400MHz with a CAS latency of CL17 and operates at 1.20V. The stick uses a 2Rx4 organisation and includes ECC with registered signalling for server and workstation platforms.

Compatibility fit

The part is validated for Lenovo systems that accept the 46W0832 part number and support DDR4 RDIMM modules. It will not work in desktop boards that require unbuffered UDIMMs, nor in laptops or small-form-factor units that use SO-DIMM slots. Buyers needing non-ECC memory or higher frequencies should look elsewhere.

Deciding specification

The registered ECC RDIMM interface is the single specification that determines whether this module fits your system. Only motherboards with registered DDR4 DIMM slots and ECC support can use this 32GB stick.

Questions about this item

How much heat and power does the 1.20 V DDR4 2400 module draw when the server runs 24/7?

At 1.20 V the registered DIMM runs at standard DDR4 voltage, so heat output stays low enough for normal server airflow without extra cooling.

What must the system already have to accept this 288‑pin ECC RDIMM?

A Lenovo server or workstation motherboard with DDR4 RDIMM slots that support registered ECC memory and 2Rx4 organisation.

Will this 32 GB CL17 stick work alongside older 2666 MHz modules in the same chassis?

Yes — the system will clock both to the lowest common speed, so 2400 MHz and 2666 MHz DIMMs can run together in compatible Lenovo platforms.
