1.5 TB DDR5 4800 ECC RDIMM kit

This 12-module kit delivers 1.5 TB of registered DDR5 4800 memory with ECC and a CL40 latency. It is built for ThinkMate Supermicro SuperServer platforms such as the 111C-NR and 121C-TN2R that require registered DIMMs. System integrators and IT teams handling virtualization or database workloads gain the capacity headroom these servers demand.

Registered ECC modules with major OEM chips

Each 128 GB DIMM uses 4Rx4 organisation and runs at 1.10 V without a heat spreader. The registered buffer and on-die ECC correct single-bit errors and reduce electrical load on the memory controller, allowing all twelve slots to be populated stably. Samsung, Micron or Hynix die selections are validated under load before shipping.

Twelve slots filled for maximum density

The kit occupies every DIMM slot on supported dual-socket boards, reaching the platform's 1.5 TB limit with DDR5 4800 bandwidth. Workloads that scale beyond this capacity or require faster memory speeds will need a different server generation or memory technology.

Questions about this item

Will the twelve 128 GB DDR5 RDIMM modules require any periodic replacement or servicing?

The modules are solid-state with no moving parts and no heat spreader, so no scheduled maintenance or replacement is needed under normal operation.

What limits sustained throughput first on this 1.5 TB DDR5 4800 CL40 4Rx4 registered kit?

The CAS latency of CL40 at 4800 MT/s sets the primary timing ceiling for continuous data flow.

How much heat and power should I expect from the full 12-module kit running all day at 1.1 V?

Each module operates at 1.1 V without a heat spreader; total power scales with the 12 x 128 GB population, so adequate chassis airflow is the main thermal consideration.
