High-Capacity Server Memory Module

This 128GB DDR4 module targets administrators upgrading or repairing enterprise servers that require registered ECC memory. The load-reduced design helps maintain signal integrity on heavily populated memory channels.

Quad-Rank LRDIMM Architecture

The module operates at DDR4 3200 with CL22 latency and 1.20V voltage using a 4Rx4 organisation. Compatibility depends on the platform’s qualified-vendor list for quad-rank LRDIMMs at this speed.

288-Pin Registered Form Factor

The 288-pin DDR4 LRDIMM form factor fits only server boards wired for registered load-reduced modules. Consumer desktop boards and platforms limited to standard UDIMMs or RDIMMs cannot use this memory.

Questions about this item

What does the 3200 MT/s rating mean when the module is installed in a server?

The module runs at DDR4 3200 (PC4 25600) with CAS latency CL22, delivering that data rate when the platform supports it.

How does the 288-pin DDR4 interface and Load Reduced design affect usable bandwidth?

The 288-pin DDR4 connection and Load Reduced architecture reduce electrical load on the memory bus, allowing the 128 GB quad-rank module to operate at the rated speed.

What physical slot and clearance does this 288-pin LRDIMM need?

It requires a standard 288-pin DDR4 DIMM slot; the quad-rank 4Rx4 layout fits the same height as other LRDIMMs in that form factor.
