Server-grade ECC LRDIMM

This single 32GB DDR4 2133MHz module uses a 4Rx4 load-reduced design with CL15 latency and 1.2V operation. It targets administrators upgrading workstations, servers or NAS systems that require registered ECC memory. The 288-pin form factor fits DDR4 slots built for LRDIMM modules. It will not work in standard desktop computers or alongside unbuffered DIMMs.

Sustained workload behaviour

Load-reduced architecture reduces electrical load on the memory bus, allowing higher capacities per channel during continuous operation. ECC corrects single-bit errors and detects multi-bit errors without halting the system. JEDEC-compliant 2133MHz timing delivers consistent throughput for virtualisation, database or file-serving tasks that run for hours.

Pre-installation checks

Verify that your platform explicitly supports DDR4 ECC LRDIMM modules and 4Rx4 rank configuration. Confirm the motherboard or system documentation lists 288-pin LRDIMM compatibility and does not restrict mixing with unbuffered or standard registered DIMMs. Ensure the BIOS or firmware is current enough to recognise the full 32GB capacity per slot.

Questions about this item

How much power does the 1.2V DDR4 module draw when the server runs all day?

The module operates at 1.2V, the standard DDR4 voltage, which keeps power draw low during continuous operation.

What must the motherboard already support for this 288-pin LRDIMM to work?

The board must accept DDR4 ECC load-reduced DIMMs at 2133MHz with 4Rx4 organisation and 288-pin layout.

Can I keep my existing unbuffered DDR4 sticks alongside this 32GB LRDIMM?

No, load-reduced ECC memory cannot be mixed with unbuffered modules; all slots must use the same registered type.
