16GB DDR4 3200 ECC RDIMM

This 16GB DDR4 3200 module is an ECC registered DIMM built for servers and workstations. It runs at PC4-25600 with CL22 latency and 1.20V standard voltage. The single-rank x4 layout uses major-brand chips on a 288-pin PCB. It is designed to boost loading times, responsiveness and workload capacity in compatible enterprise systems.

Suits ECC registered platforms only

This memory fits systems that require DDR4 ECC RDIMM modules and will not work in desktop or laptop computers that use unbuffered non-ECC DIMMs. Buyers who need memory for consumer motherboards should look elsewhere. Verify your platform’s qualified-vendor list and channel population rules before purchasing to ensure correct operation.

16GB per module headroom

A single 16GB stick adds substantial capacity for virtualisation, databases or compute tasks that benefit from registered ECC integrity. Multiple modules can scale further within the platform’s slot and channel limits. Workloads that exceed the per-module density or the board’s maximum supported memory will require higher-capacity RDIMMs or additional populated channels.

Questions about this item

My motherboard only has standard 288-pin DDR4 slots — will this registered ECC module work in them?

No, this module is a registered ECC RDIMM designed for server and workstation platforms that specifically support registered memory; it will not function in standard desktop or laptop motherboards.

I plan to add this 1Rx4 stick alongside older dual-rank DDR4 3200 ECC RDIMMs — will the mixed ranks cause issues?

Mixing single-rank and dual-rank registered ECC modules is often supported, but population rules vary by platform; consult your system manual for approved slot configurations and rank-mixing guidelines.

After installing the module, how can I confirm it is running at the rated 3200 MT/s with ECC active?

Check the BIOS memory information screen or use a tool such as dmidecode on Linux to verify the speed shows 3200 MT/s and the ECC status reports as enabled.
