32GB DDR4 ECC Registered RDIMM

This 32GB DDR4 module runs at 3200 MT/s with CL22 latency and 1.2 V operation. It uses a 288-pin 2Rx4 registered design with on-die ECC for data integrity. The part is validated for Gigabyte MZ32-AR0, MZ32-AR1, MZ71-CE0, MZ71-CE1 and MZ72-HB0 server and workstation platforms.

Passive operation and low voltage

No heat spreader is fitted, so the module relies on chassis airflow for cooling. The 1.2 V JEDEC standard voltage keeps power draw modest under typical server workloads. Silent operation is assured because there are no active cooling components on the DIMM itself.

Registered ECC for dense server builds

The registered buffer reduces electrical load on the memory controller, allowing higher capacities per channel. It cannot be mixed with unbuffered or load-reduced DIMMs. The module drops into standard 288-pin DDR4 slots and is backward compatible with 2133, 2400, 2666 and 2933 MT/s bus speeds. It is not suitable for consumer desktop motherboards.

Questions sur cet article

How do I install the 288-pin DDR4 ECC RDIMM in my Gigabyte MZ32-AR0, and what step do people often get wrong?

Align the notch on the module with the slot key, press straight down until the retention clips click, and ensure the system is fully powered off — not just in sleep — before seating the registered DIMM.

What maintenance or replacement will the 32GB 2Rx4 module need over its service life?

No routine maintenance is required; the module has no heat spreader and runs at 1.2V, so replacement is only needed if a memory test reports correctable ECC errors that exceed the platform threshold.

What limit appears first when the RDIMM runs sustained workloads at 3200 CL22?

The registered buffer adds one cycle of latency, so memory-controller throughput saturates before the DRAM cells reach thermal limits, making bandwidth the first bottleneck under continuous load.
