System-Specific DDR5 Server Memory Kit

This NEMIX RAM kit delivers 1.5TB of DDR5 ECC registered memory across twelve 128GB modules. It is built for the Thinkmate RAX-XS4-21S4 rackmount server. IT teams managing memory-intensive workloads on this specific platform will find the kit matches the system's qualified configuration.

Registered 4Rx4 Organisation at 4800 MT/s

Each module uses a 4Rx4 layout and runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1V. The registered buffer and ECC function are required by the Thinkmate server's memory controller; unbuffered or non-ECC DIMMs will not operate in this platform.

Twelve-Module Kit Simplifies Deployment

The package supplies all twelve 288-pin RDIMMs in a single matched set, eliminating the need to source individual sticks and reducing the risk of mixing revision codes. No heat spreaders are included, so airflow in the server chassis must accommodate bare modules.

Questions about this item

What does 1.5 TB across twelve modules mean once the kit is installed in the Thinkmate RAX-XS4-21S4?

The server sees a single 1.5 TB memory pool built from twelve 128 GB RDIMMs, all running at DDR5 4800 with CL40 latency and ECC protection.

What does the DDR5 4800 (PC5 38400) rating cap in practice?

Each module is limited to 4800 MT/s transfer rate and 1.1 V operation; the registered design and CL40 timing apply to every slot populated.

What does the 288-pin 4Rx4 RDIMM form factor need to fit in the chassis?

Twelve standard DDR5 RDIMM slots with 288-pin keying, 1.1 V power delivery and enough clearance for modules without heat spreaders.
