64GB DDR4 2133 ECC LRDIMM Server Module

This 64GB DDR4 2133 ECC LRDIMM module uses a 4Rx4 load-reduced design to deliver high-density memory for server and workstation platforms. It operates at 1.20V with CL15 latency and fits 288-pin DIMM slots. The specification targets administrators upgrading Dell systems referencing part numbers A8451131, A8718891 and SNP03VMYC/64G.

Sustained Load Behaviour of Load-Reduced DIMM

The load-reduced architecture buffers the command and address bus to lower electrical load on the memory controller during continuous operation. This helps maintain signal integrity when all ranks are active for extended periods. ECC circuitry corrects single-bit errors on the fly to protect data integrity under sustained workloads.

Upgrade Scope and Compatibility Check

The module replaces or adds to existing DDR4 2133 ECC LRDIMM configurations in compatible Dell servers. It is not suitable for systems that require standard registered DIMMs, unbuffered DIMMs or a different DDR generation. Verify the platform memory specification before purchase to confirm support for 4Rx4 LRDIMM population rules.

Questions about this item

How much power does the 1.2V 64GB DDR4 2133 LRDIMM draw when running continuously?

The module operates at the standard DDR4 voltage of 1.2V; load-reduced buffering reduces electrical load on the memory bus, which helps keep thermals manageable during sustained use.

What must my motherboard provide to run this 288-pin ECC LRDIMM?

A DDR4 DIMM slot that supports ECC and load-reduced registered DIMMs at 2133 MHz, plus a BIOS that can initialise 4Rx4 modules at 1.2V.

Will this CL15 4Rx4 module work alongside existing 2Rx4 DDR4 2133 ECC RDIMMs?

Mixing ranks and registered types is not recommended; the motherboard must support both LRDIMM and RDIMM populations simultaneously, which most server platforms do not allow.
