ECC UDIMM for Workstations and NAS

This 8 GB DDR4 module runs at 3200 MT/s with CL22 latency and 1.2 V operation. It is an unbuffered ECC DIMM designed for desktop PCs, workstations, servers and NAS systems. The 288-pin form factor fits standard DDR4 slots and meets JEDEC specifications for reliable data integrity.

Suited for ECC Platforms Only

The module targets users who need error-correcting memory for ZFS storage pools, virtualisation hosts or workstation workloads. Systems without ECC support in the CPU or chipset will not benefit from the feature and should use standard non-ECC memory instead. Compatibility extends to platforms rated for 2133, 2400, 2666 and 2933 MT/s speeds.

8 GB Capacity with Backward Speed Support

A single 8 GB stick handles everyday multitasking, light virtualisation and NAS caching duties. Workloads that require larger datasets or many concurrent virtual machines will exceed this capacity and need additional modules. The DDR4 3200 rating also covers 2133, 2400, 2666 and 2933 MT/s operation for mixed-speed environments.

Questions about this item

Does my motherboard need 288-pin DDR4 slots that support ECC unbuffered DIMMs for this module to work?

Yes, the module is a 288-pin DDR4 ECC unbuffered DIMM that requires a motherboard with DDR4 slots and explicit ECC support in the chipset or BIOS.

Will this 3200MHz CL22 stick run with my existing 2400MHz DDR4 ECC modules?

The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz speeds, so it will downclock to match the slowest installed kit.

How can I confirm the RAM is running at 3200MHz with ECC active after installation?

Check the memory speed and ECC status in your BIOS or UEFI, or use an OS tool such as dmidecode on Linux or CPU-Z on Windows to verify 3200MHz operation and ECC enablement.
