2TB DDR5 ECC RDIMM kit

This 2TB kit contains sixteen 128GB DDR5 4800 registered DIMMs with ECC and a CL40 latency at 1.1V. It is built for servers and workstations that need maximum registered memory capacity.

Registered 4Rx4 organisation

Each module uses a 4Rx4 layout and registered buffering to support the full 2TB density across sixteen slots. The ECC function corrects single-bit errors to protect data integrity in critical workloads.

Sixteen-slot requirement

Verify that your motherboard provides sixteen 288-pin DDR5 RDIMM slots and supports 4Rx4 registered modules at this density. Systems with fewer slots or unbuffered-only memory controllers cannot use this kit.

Questions about this item

Will the 16 modules ever need active cooling added later?

The kit ships without heat spreaders, so sustained full-load operation in a dense chassis may require directed airflow across the 288-pin DDR5 modules.

What caps total throughput first when all 16 modules run at 4800 MT/s continuously?

The memory controller's maximum supported channel count and rank-per-channel limit will saturate before the CL40 4Rx4 modules reach their own bandwidth ceiling.

How much heat and power does the 2 TB kit produce at 1.1 V around the clock?

At 1.1 V nominal voltage the 16×128 GB registered DIMMs draw steady power proportional to active ranks, generating measurable heat that scales with sustained write-intensive workloads.
