High-Density Server Memory Kit

This 1.5TB kit contains twelve 128GB DDR4 RDIMMs rated at 2933 MT/s with CL21 latency. It is built for enterprise servers and workstations that require registered ECC memory to maintain data integrity under heavy workloads.

Registered Design for Stable Operation

Each module uses an 8Rx4 organisation and operates at 1.2V without a heat spreader. The 288-pin registered interface buffers address and command signals, reducing electrical load on the memory controller when all twelve slots are populated.

Baseline Power and Thermal Profile

Running at the standard 1.20V DDR4 voltage keeps power draw predictable in fully populated systems. Passive cooling relies on chassis airflow across the bare PCB, so adequate case ventilation is necessary to sustain stability during sustained high-throughput tasks.

Questions about this item

What DDR4 standard and speed does this 12-module kit run at?

The kit operates at DDR4 2933, also labelled PC4-23400, with a CAS latency of CL21 at 1.20 V.

What physical slot and module count does the 1.5 TB kit require?

It uses twelve 288-pin DDR4 RDIMM modules, so the motherboard must provide twelve matching DIMM slots.

How are these registered ECC modules installed, and what step is often missed?

Insert each 128 GB RDIMM firmly until the latches click, then verify the BIOS recognises all twelve modules and enables ECC.
