Capacity and form factor

This Crucial module delivers 128 GB of DDR4 memory in a single 288-pin LRDIMM package. It runs at 3200 MHz with a CAS latency of 22 and uses quad-rank 16 Gbit chips.

Workstation and server builders

The high density suits systems that need maximum capacity per slot for virtualization or large datasets. Builders whose boards only accept standard UDIMMs or who require lower latency timings should look at something else.

Questions about this item

Will this 288-pin DDR4 LRDIMM fit in my standard desktop motherboard?

This module uses a 288-pin LRDIMM form factor. LRDIMMs require a motherboard with registered-memory support and are not compatible with standard consumer desktop boards that accept only unbuffered UDIMMs.

How will the quad-rank design affect my system if I add this alongside existing memory?

The module is quad-rank (4Rx4). Each rank adds electrical load to the memory controller; mixing ranks can limit the maximum stable speed or total capacity your platform supports.
