2TB DDR5 ECC RDIMM kit

This 2TB kit contains sixteen 128GB DDR5 4800 modules built for Thinkmate RAX-QE12 rackmount servers. Registered ECC design with 4Rx4 organisation and 1.10V operation targets enterprise workloads that demand maximum capacity and data integrity. It is not for desktops, laptops or consumer motherboards that lack RDIMM support.

4800 MT/s CL40 registered timing

Speed is DDR5 4800 (PC5-38400) with CAS latency 40 across all sixteen modules. The 288-pin RDIMM form factor and registered buffer ensure signal stability at full population. Buyers needing higher frequency or lower latency must select a different specification.

Thermals noise and power

Modules run at 1.10V without heat spreaders, relying on server chassis airflow for cooling. Registered buffering adds minimal power overhead per DIMM. Acoustic output depends entirely on the host system fan profile rather than the memory itself.

Questions about this item

What does the 4800 MT/s speed mean once these modules are installed in a Thinkmate RAX-QE12 server?

The server's memory controller will run the kit at DDR5-4800, delivering PC5-38400 bandwidth across all 16 slots when populated with supported processors.

How does the DDR5 RDIMM interface and CL40 latency affect real-world throughput?

Registered DDR5 modules add a clock cycle for command buffering, and CL40 sets the minimum read latency at that data rate.

What physical requirements must the chassis and motherboard meet for these 288-pin modules?

Each 128 GB stick uses the standard 288-pin DDR5 RDIMM form factor and operates at 1.1 V, so the board needs 16 DDR5 RDIMM slots and adequate clearance.
