Dell-Compatible 64GB LRDIMM for Servers

This 64GB DDR4-2133 ECC load-reduced DIMM is built for Dell servers that require registered memory with 4Rx4 organisation. It operates at 1.20V with a CAS latency of CL15 and uses a standard 288-pin DDR4 form factor. The module is validated as a direct replacement for Dell part number A8451131.

Sustained Load Behaviour with ECC and Load Reduction

Error-correcting code and the load-reduced architecture work together to maintain data integrity during continuous, high-capacity workloads. The 4Rx4 rank structure allows the memory controller to address more banks per channel, reducing electrical loading on the bus. This helps sustain throughput in virtualisation and database tasks that keep memory saturated for long periods.

Verify Slot Count and Maximum Capacity Before

Confirm that your Dell server supports 64GB LRDIMMs per slot and that the total installed memory will not exceed the platform limit. The module requires a motherboard that accepts DDR4 registered ECC memory at 2133 MT/s. Systems limited to UDIMMs or lower single-DIMM capacities will not accept this part.

Questions about this item

How much power does the 64GB DDR4-2133 LRDIMM draw at its 1.20V rating during continuous operation?

The module runs at 1.20V, the standard DDR4 voltage, so power draw per stick stays low even under sustained server workloads.

What server slot and chipset support are required to install this 288-pin ECC LRDIMM?

It needs a DDR4 288-pin LRDIMM slot and a platform that supports 4Rx4 Load-Reduced ECC modules at DDR4-2133.

Can this 4Rx4 CL15 module share channels with older 2Rx4 DDR4 DIMMs in the same Dell server?

Mixing 4Rx4 LRDIMMs with 2Rx4 RDIMMs is not supported; all populated slots should use identical 4Rx4 LRDIMMs for stable operation.
