Capacity and Compatibility

This 1.5 TB kit delivers twelve 128 GB DDR5 RDIMM modules tuned to 4800 MT/s with CL40 latency. Registered ECC architecture targets Supermicro H13SSL-N motherboards that require 288-pin registered memory for full-capacity operation.

Sustained Load Behaviour

Registered buffering offloads the memory controller so all twelve slots remain stable at rated speed under continuous throughput. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs.

Build and Connectors

Modules use a bare 288-pin RDIMM form factor without heat spreaders, relying on server chassis airflow for cooling. The 2Rx4 organisation matches the board's population rules, so each DIMM seats directly in the prescribed slots.

Questions about this item

How much power does the 1.1 V DDR5 kit draw when the server runs continuously?

Each module operates at 1.10 V, the standard DDR5 voltage, so total power scales with the 12 populated slots; the registered design reduces electrical load on the memory controller during sustained workloads.

What motherboard slot type and population rules must my Supermicro H13SSL-N already support for this 12 x 128 GB kit to function?

The board needs 288-pin DDR5 RDIMM slots and must allow 12 x 128 GB 2Rx4 registered ECC modules; consult the manual for the exact population order before installing.

Will the registered ECC design keep the system stable if I mix these 4800 MHz modules with slower DDR5 DIMMs already installed?

The memory controller will down-clock all modules to the lowest common speed and latency; registered buffering helps signal integrity, but matched kits are recommended for full 4800 MHz operation.
