64GB DDR4-2133 LRDIMM for servers

This Samsung module delivers 64GB of DDR4-2133 memory in a load-reduced ECC format. It operates at 1.20V and carries Supermicro certification for qualified platforms. The PC4-17000 rating matches enterprise memory standards. It is built for multi-socket servers that require high density per slot.

Verify DDR4 LRDIMM support and slot population rules

Confirm the motherboard accepts load-reduced DDR4 DIMMs and check the qualified vendor list for this part number. Registered and unbuffered modules cannot be mixed with LRDIMMs in the same channel. The system BIOS must support the density and organisation of this 64GB stick. Populate slots according to the platform memory guide.

Low-voltage operation reduces heat in dense

At 1.20V the module draws less power per gigabyte than higher-voltage alternatives. Load-reduced buffering lowers electrical load on the memory controller, helping thermals in fully populated chassis. Standard server airflow is sufficient for normal operation. No additional cooling provisions are required beyond the system design.
