ThinkMate RAX-QE12 DDR5 384GB Kit

This 384GB kit contains six 64GB DDR5 4800 CL40 registered ECC RDIMMs built for the ThinkMate RAX-QE12 rackmount server. The 2Rx4 modules operate at 1.1V and use 288-pin DDR5 form factor. It targets administrators who need maximum registered memory capacity in that specific platform.

Sustained Load Behaviour

Registered buffering and on-die ECC protect data integrity during continuous multi-threaded workloads such as virtualization hosts or database services. The CL40 latency and 4800 MT/s transfer rate remain stable across all twelve ranks because the memory controller manages each 2Rx4 module identically under prolonged thermal stress.

Pre-Installation Checks

Verify that the RAX-QE12 has twelve free DDR5 RDIMM slots and that the BIOS revision supports 64GB 2Rx4 registered modules at 4800 MT/s. Confirm the system power budget accommodates six additional 1.1V DIMMs and that the operating system licence permits 384GB of addressable memory.

Questions about this item

How much power does each 64 GB DDR5 4800 registered DIMM draw at 1.1 V?

Each module operates at 1.1 V, the standard voltage for DDR5 registered server memory, keeping power draw low during continuous operation.

What motherboard slots are required for this 6 x 64 GB kit?

The kit uses 288-pin DDR5 RDIMM form factor, so the server must provide six compatible registered DIMM slots.

Will the CL40 registered DIMMs work alongside other DDR5 RDIMMs I might keep?

Mixing is possible only if the existing modules are also DDR5 4800 CL40 2Rx4 registered DIMMs; otherwise the system will default to the slowest common speed.
