Server Memory for ECC Workloads

This 16GB DDR4 RDIMM delivers 3200 MT/s bandwidth with CL22 latency and on-die ECC. The registered signal processing adds stability for multi-DIMM server configurations. It suits virtualisation hosts, database nodes and other workloads that require error correction.

Verify Platform Compatibility

Confirm the motherboard supports DDR4 RDIMMs at 3200 MT/s and accepts 288-pin registered modules. ECC functionality requires a compatible CPU and chipset; unbuffered or consumer boards will not recognise the registered design. Mixing with unbuffered or different-rank DIMMs can prevent boot.

Thermals and Power Profile

Operating at 1.20V keeps power draw low for a registered module, reducing heat output in dense chassis. Passive cooling via system airflow is typical; no active fan on the DIMM itself. The single-rank 1Rx8 organisation limits electrical load per channel, helping sustained throughput under load.

Questions about this item

Does the 288-pin DDR4 RDIMM ship as a single 16GB module or do I need to buy anything else to install it?

The package contains one 16GB DDR4 3200 RDIMM; no extra parts are required for installation in a compatible server board.

How do I decide between this CL22 1Rx8 stick and other capacities or ranks?

Choose this 16GB 1Rx8 module when your server needs registered ECC memory at 3200MT/s and you want a single rank per channel for maximum stability.

What does the 3200MT/s rating actually deliver once the module is seated in a server?

The module runs at 3200MT/s (PC4-25600) with CL22 latency at 1.20V, providing registered ECC throughput for supported DDR4 server platforms.
