64GB DDR4 LRDIMM for servers

This A-Tech module delivers 64GB of DDR4 memory in a single 288-pin LRDIMM package. It operates at 2400MHz with a CAS latency of 17 and runs at the standard 1.2V voltage. The load-reduced design and ECC support target server and workstation platforms that require high-density, error-correcting memory.

Sustained-load behaviour

The 4Rx4 organisation and load-reduced architecture reduce electrical loading on the memory bus, helping maintain signal integrity when all slots are populated. ECC circuitry detects and corrects single-bit errors during continuous operation, while the major-brand chipset and 1.20V operation keep power draw stable under extended workloads.

Compatibility checks

Verify that your motherboard supports DDR4 LRDIMM modules and accepts 4Rx4 ranks at the 2400MHz data rate. Confirm the system BIOS recognises 64GB single-module capacity and that the platform’s qualified-vendor list includes this specification. Ensure the DIMM slot keying matches the 288-pin DDR4 form factor before ordering.

Questions about this item

How much power does a 64GB DDR4 2400 ECC LRDIMM draw at 1.2V running continuously in a server?

Each module operates at the standard DDR4 voltage of 1.2V, keeping power draw low for high-density 4Rx4 server configurations.

What motherboard slot and CPU memory controller are required for this 288-pin LRDIMM to function?

A DDR4 server platform with a 288-pin DIMM slot and a CPU memory controller that supports Load Reduced ECC memory is required.

Can this CL17 2400MHz LRDIMM share a channel with older DDR4 RDIMMs in the same server?

Mixing LRDIMMs with standard RDIMMs on the same memory channel is not supported; all slots in a channel must use the same module type.
