32GB DDR4-2133 ECC LRDIMM

This 32GB module uses DDR4-2133 (PC4 17000) with load-reduced registered signalling and ECC. It is built for servers and workstations that require registered memory topology and error correction at standard voltage.

Platform compatibility check

Verify that your motherboard supports DDR4 LRDIMM modules and accepts 4Rx4 organisation at 1.20V. Systems limited to UDIMM or RDIMM only will not operate with this load-reduced form factor.

Sustained-load behaviour

Load-reduced buffering reduces electrical load on the memory controller, helping maintain signal integrity during continuous multi-threaded workloads. ECC correction handles single-bit errors without interrupting long-running compute tasks.

Questions about this item

Does the HMA84GL7AMR4N-TF module ship alone or with any extra components?

The module is supplied as a single 32GB DDR4-2133 4Rx4 ECC LRDIMM; no cables, brackets or additional parts are included.

When would I choose this 32GB 2133 MT/s load-reduced DIMM over other capacities or speeds?

Select this 32GB PC4-17000 LRDIMM when your server platform requires registered ECC memory at 1.20V and the qualified-vendor list specifies 2133 MT/s operation.

What does the 2133 MT/s rating mean once the DIMM is installed in a server?

The memory controller will transfer data at up to 2133 million transfers per second, delivering a peak bandwidth of 17000 MB/s per module at 1.20V.
