Capacity and compatibility

This kit delivers 1.5 TB of DDR5 memory across twelve 128 GB registered DIMMs built for the Thinkmate RAX-QE12 rackmount server. Each module runs at 4800 MT/s with a CAS latency of 40 at 1.1 V. The 4Rx4 organisation and ECC support target enterprise workloads that demand maximum density and data integrity.

Registered ECC behaviour

Registered buffering reduces electrical load on the server memory controller, allowing all twelve slots to be populated without signal degradation. On-die ECC corrects single-bit errors transparently, protecting databases and virtualisation hosts from silent corruption. The kit arrives as a matched set so the platform can initialise the full 1.5 TB at rated speed without manual tuning.

Physical installation

Standard 288-pin DDR5 RDIMM form factor fits the RAX-QE12 DIMM sockets directly; no adapters or risers are required. Modules ship without heat spreaders, relying on the server's directed airflow for cooling. Installers should follow the system manual's population sequence to ensure correct channel interleaving and optimal bandwidth.

Questions about this item

Will the 12 modules of 128 GB each ever need individual replacement?

The kit contains twelve 128 GB DDR5 RDIMMs; if a single module fails you replace only that stick, not the entire 1.5 TB set.

What latency appears first when the 4800 MT/s CL40 memory runs continuously?

Sustained workloads hit the CL40 CAS timing on every access; that fixed latency is the first limit you measure under load.

How much heat do the twelve 1.1 V registered DIMMs produce in a rack server running all day?

Each 128 GB 4Rx4 module operates at 1.1 V without a heat spreader; total power scales with all twelve slots populated in the Thinkmate RAX-QE12.
