128GB DDR4 2666MHz ECC LRDIMM Server Module

This 128GB DDR4 2666MHz ECC LRDIMM module is built for server systems that require high-capacity registered memory. It suits administrators upgrading or repairing compatible enterprise platforms. The load-reduced design helps maintain signal integrity on densely populated memory channels.

2S4Rx4 8Rx4 3DS TSV Rank Configuration

The decisive specification is the 2S4Rx4 organisation using 8Rx4 3DS TSV stacking. This rank structure determines whether the memory controller can address the full 128GB capacity. Verify that your platform supports this exact rank geometry before purchase.

288-Pin DDR4 1.20V CL15 Form Factor

The module uses a standard 288-pin DDR4 DIMM interface at 1.20V with CL15 latency. It requires a server motherboard with DDR4 LRDIMM slots and a memory controller qualified for 2666MHz operation. No heat spreader is fitted, so airflow across the module must be provided by the chassis.

Perguntas sobre este artigo

How much capacity does the 128GB DDR4 2666 module add to a server?

The module adds 128GB of ECC LRDIMM capacity in a single 288-pin DIMM, expanding total system memory by that amount when installed in a compatible slot.

What does the PC4-21300 DDR4 2666 rating mean for actual data rate?

PC4-21300 denotes DDR4 2666 MT/s operation; the memory controller in the server determines the realised bandwidth within that specification.

What physical slot and clearance does the 288-pin LRDIMM require?

It fits a standard 288-pin DDR4 DIMM socket and has no heat spreader, so it needs only the normal DIMM slot clearance in the server chassis.
