Server Memory Upgrade

This 16GB DDR4 2133 ECC LRDIMM module is built for servers and workstations that require registered load-reduced memory. It operates at 1.20V with CL15 latency and uses a 2Rx4 rank configuration. The 288-pin DIMM fits systems designed for DDR4 PC4-17000 registered memory.

Sustained Workload Behaviour

Load-reduced buffering reduces electrical load on the memory controller, helping maintain signal integrity when all slots are populated. ECC circuitry corrects single-bit errors during continuous operation, supporting data integrity under heavy multitasking or virtualization loads.

Compatibility Check

Verify that your platform supports DDR4 ECC LRDIMM modules at 2133MHz and accepts a 2Rx4 rank layout. Cross-reference the HP part numbers 726720, 752371, 774173 with your system documentation before ordering. Ensure the motherboard provides 1.2V DDR4 power and 288-pin registered DIMM slots.

Questions about this item

How much power does the 1.20V DDR4 2133 module draw when the server runs continuously?

The module operates at 1.20V standard DDR4 voltage; Load Reduced design lowers electrical load on the memory bus, reducing heat during all-day operation.

What must the system already support for this 288-pin ECC LRDIMM to function?

The motherboard must accept DDR4 2133 ECC LRDIMM 2Rx4 modules at 1.20V and provide a 288-pin DIMM slot; verify the server's qualified-vendor list before installing.

Will this 2Rx4 LRDIMM work alongside older registered DIMMs already in my HP server?

Mixing Load Reduced and standard registered DIMMs is not supported; all slots must use the same LRDIMM type for the memory controller to initialise correctly.
