64GB DDR4 2933 ECC LRDIMM for Servers

This 64GB DDR4 2933 module uses load-reduced ECC technology to serve enterprise servers and workstations that require registered memory. The 4Rx4 organisation and 1.2V operation match Micron MTA72ASS8G72LZ-2G9D1 specifications for direct replacement. IT teams select it for capacity-intensive virtualisation hosts and database nodes.

Sustained Load Behaviour with 4Rx4 Organisation

Under continuous workloads the quad-rank layout spreads accesses across four ranks per channel, reducing per-rank pressure during extended compute passes. ECC corrects single-bit errors on the fly so long-running jobs maintain data integrity without interruption. The 1.2V supply keeps power draw stable across hours of sustained throughput.

Thermals and Power in Normal Operation

Running at 1.2V the module operates without a heat spreader, relying on chassis airflow to maintain safe temperatures during typical server duty cycles. Load-reduced buffering lightens the electrical load on the memory controller, contributing to lower overall system power draw. Silent operation is assured because no active cooling is attached to the DIMM.

Questions about this item

How much power does the 1.2 V DDR4 2933 module draw when the server runs continuously?

The module operates at 1.20 V, the standard DDR4 voltage, so power draw stays at the JEDEC baseline for 2933 MT/s LRDIMMs rather than exceeding it.

What must the motherboard provide for this 288-pin ECC LRDIMM to function?

A DDR4 LRDIMM slot with 288-pin keying, registered ECC support, and a BIOS that accepts 4Rx4 load-reduced modules at 2933 MT/s.

Will this 64 GB 4Rx4 stick work in an older DDR4 board that only supports 2Rx4 registered DIMMs?

No — the 4Rx4 organisation and load-reduced signalling require a motherboard and memory controller qualified for LRDIMM 4Rx4 operation.
