Lenovo NeXtScale nx360 M5 server memory

This 32 GB DDR4 2400 CL17 ECC Registered RDIMM is built specifically for the Lenovo NeXtScale nx360 M5 platform. It operates at 1.2 V and uses a 288-pin 2Rx4 layout to deliver 32 GB per module in server and workstation environments.

Installation notes and common issues

The module inserts like any standard RDIMM but must go into a slot that supports ECC Registered memory; unbuffered DIMMs cannot be mixed with this type. Systems that do not explicitly list ECC Registered support will not POST with these modules installed.

Suited for NeXtScale nx360 M5 upgrades.

Buyers maintaining or expanding a Lenovo NeXtScale nx360 M5 (E5-2600 v4) chassis can use this as a direct replacement for Lenovo part numbers 46W0832, 46W0833, 46W0835, 4X70G88320 and 4X70M09263. Builders needing standard desktop memory or unbuffered ECC should select a different module type.
