Server memory kit

This 1.5TB kit contains six 256GB DDR4 LRDIMMs rated at 2933MHz with CAS latency 21. It is built for servers that require ECC load-reduced modules and is not suitable for standard PC computers. Each module operates at 1.2V and uses an 8Rx4 organisation.

Build integration

The 288-pin LRDIMM form factor fits server boards that support DDR4 2933 PC4-23400 load-reduced memory. ECC and the load-reduced design reduce electrical load on the memory controller, freeing signal integrity headroom for large-capacity configurations. Modules use major OEM Samsung, Micron or Hynix components.

Sustained operation

Rated voltage of 1.2V and the load-reduced architecture help maintain stability during extended workloads. ECC corrects single-bit errors on the fly, protecting data integrity over long run times. The 8Rx4 rank structure supports high density without exceeding the controller's electrical limits.

Questions about this item

How does the 8Rx4 rank configuration affect maximum capacity per channel?

Each 256 GB module uses an 8Rx4 organisation, so a single DIMM places eight ranks on the channel; the platform memory controller must support that rank count per slot to reach the full 1.5 TB kit capacity.

What thermal load should be expected from six 1.2 V LRDIMMs running continuously at 2933 MHz?

Six load-reduced modules at 1.2 V draw steady power across all ranks; sustained operation requires server-grade airflow to keep each 288-pin DIMM within its thermal envelope.

Which motherboard features are required for this DDR4 2933 MHz ECC LRDIMM kit to function?

The board must provide DDR4 288-pin slots, registered ECC support, and a memory controller qualified for 8Rx4 load-reduced DIMMs at the PC4-23400 data rate.
