96GB DDR5 6400MHz ECC RDIMM

This 96GB registered DDR5 module runs at 6400MHz with CL32 latency and 1.10V operation. It targets server and workstation administrators who need high-capacity error-correcting memory for virtualisation, database or compute workloads.

Build integration: registered DDR5 slot and power

The 288-pin RDIMM form factor requires a motherboard with registered DDR5 slots and a chipset that supports 2Rx4 organisation. The module frees DIMM slots by delivering 96GB in a single stick, reducing the total module count needed for large memory configurations.

No heat spreader and major-brand ICs

The bare PCB design relies on system airflow for cooling, so chassis ventilation must be adequate. Major-brand DRAM ICs and factory testing aim to deliver stable operation at the rated 6400MHz speed without additional tuning.

Questions about this item

Will the 96GB DDR5 6400MHz ECC RDIMM 2Rx4 module hit capacity limits first in a server?

The module provides 96GB of capacity in a single 288-pin slot; whether that becomes the first limit depends on how many slots your board has and the total memory your workload requires.

Does the 1.10V DDR5 6400MHz registered module run hotter or louder than standard DDR5 under continuous load?

It operates at the standard 1.10V DDR5 voltage with no heat spreader, so thermals depend on your chassis airflow; registered modules add negligible power draw versus unbuffered DDR5 at the same speed.

What motherboard features must I already have for this 288-pin DDR5 6400MHz ECC RDIMM to work?

You need a DDR5 RDIMM-capable platform with 288-pin slots that supports ECC, registered operation, 6400 MT/s (PC5-51200) and 2Rx4 rank configuration.
