128GB DDR5 4800 ECC RDIMM for Thinkmate RAX-QE12

This 128GB DDR5 4800 registered DIMM is built for the Thinkmate RAX-QE12 rackmount server. It delivers ECC protection and registered signalling for stable operation in mission-critical workloads. The single-module design simplifies capacity expansion in dense configurations.

ECC registered DDR5 at 4800 MT/s with CL40 latency

The module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40 and 1.10V voltage. Error-correcting code and registered buffering maintain data integrity under sustained server loads. The 4Rx4 organisation supports high-density memory populations.

One 128GB module fills a single 288-pin slot

A single 128GB stick provides substantial capacity headroom for virtualization, databases and large datasets. The 4Rx4 rank structure maximises density per channel. Systems requiring more than 128GB per channel or non-ECC memory will need a different module type.

Questions about this item

What does the 128 GB capacity mean once this module is installed in a Thinkmate RAX-QE12?

The single 128 GB DDR5 4800 RDIMM adds 128 GB of registered ECC memory to one DIMM slot on the Thinkmate RAX-QE12 server.

What does the PC5-38400 designation tell me about the module interface and its practical limit?

PC5-38400 identifies a DDR5 4800 MT/s 288-pin RDIMM interface; the registered buffer and ECC operate at the 4800 MT/s data rate.

What physical requirements must the chassis and motherboard meet to accept this 288-pin DDR5 RDIMM?

The module needs a standard 288-pin DDR5 RDIMM slot, 1.1 V power, and clearance for a bare board without a heat spreader.
