768 GB DDR5 ECC kit for Thinkmate RAX-QE12

This registered DDR5 4800 memory kit delivers 768 GB across six 128 GB modules. It is built for the Thinkmate RAX-QE12 rackmount server and targets IT teams running virtualization, databases or heavy multi-threaded workloads that demand maximum capacity with error correction.

288-pin RDIMM form factor with 4Rx4 organisation

Each module uses a 288-pin DDR5 RDIMM design operating at 1.10 V and CL40 latency. The registered buffer and 4Rx4 layout reduce electrical load on the memory controller, allowing all twelve slots to be populated without signal degradation in the RAX-QE12 platform.

Replaces lower-capacity DDR5 RDIMM sets when 768

The jump is worth it when the workload exceeds the capacity of smaller kits and the server’s memory controller supports the full 6 x 128 GB population. Buyers who need fewer than six modules or a lower total capacity should select a smaller kit instead.

Questions about this item

What speed does the DDR5 4800 interface actually run at in this kit?

The kit operates at DDR5 4800 (PC5-38400) with a CAS latency of CL40.

What physical slot and form factor do these modules require?

Each 128 GB module is a 288-pin DDR5 RDIMM without a heat spreader.

How are the six modules installed and what step is often missed?

Populate all six slots per the server manual and ensure each RDIMM clicks fully into the 288-pin socket.
