64 GB DDR4 LRDIMM for servers

This 64 GB DDR4 2400 LRDIMM uses a 4Rx4 quad-rank Samsung chipset and operates at 1.2 V with CL17 latency. It is built for Supermicro platforms that require ECC load-reduced memory to support large-capacity configurations.

Check motherboard LRDIMM support and rank limits

Verify that your server board accepts 288-pin DDR4 LRDIMMs and can address 4Rx4 modules at the full 64 GB capacity per slot. Confirm the maximum supported memory speed and total system capacity before ordering to avoid compatibility issues.

Sustained load stability with ECC and load reduction

Under continuous workloads the ECC circuitry corrects single-bit errors while the load-reduced buffer reduces electrical stress on the memory controller. The 1.2 V standard voltage helps maintain consistent thermal behaviour during extended operation.

Questions about this item

What comes in the box and do I need anything else to install it?

The package contains one 64GB LRDIMM module; no extra parts are required for installation beyond a compatible 288-pin DDR4 server slot.

Should I pick this 64GB 4Rx4 LRDIMM or a different capacity or rank?

Choose this 64GB 4Rx4 LRDIMM when your server needs maximum capacity per slot and supports quad-rank load-reduced modules; select a lower-capacity or dual-rank DIMM if your platform limits rank count per channel.

What does the 2400 MHz CL17 rating mean for real-world server performance?

The module runs at 2400 MHz with CAS latency 17 at 1.2V, delivering PC4-19200 bandwidth for memory-intensive workloads such as virtualization and large databases.
