16 GB DDR4 3200 ECC RDIMM for Servers

This 16 GB DDR4 3200 module is a registered ECC DIMM built for server and workstation platforms. It runs at 1.2 V with CL22 latency and uses a 1Rx4 organisation on major-brand chips. The 288-pin form factor matches standard DDR4 DIMM slots in compatible systems.

Who This Suits and Who Should Look Elsewhere

This module suits administrators upgrading or repairing systems that require registered ECC memory at DDR4 3200 speeds. It is not for desktop boards that accept only unbuffered non-ECC DIMMs, nor for builds needing capacities beyond a single 16 GB stick. Buyers who want higher frequencies, lower latencies, or consumer form factors should look at other product lines.

Build Integration Notes

The stick plugs directly into a 288-pin DDR4 DIMM slot wired for registered ECC operation. No extra power cables or cooling brackets are required beyond normal server airflow. Because it is a single-rank 1Rx4 module, it leaves additional DIMM slots free for further capacity expansion within the platform’s supported limits.

Questions about this item

Does my server motherboard need 288-pin DDR4 DIMM slots to use this module?

Yes, this is a 288-pin DDR4 RDIMM that only fits motherboards with matching DDR4 registered DIMM slots.

Will this ECC RDIMM work in a system that currently uses non-ECC unbuffered DDR4 memory?

No, registered ECC modules cannot be mixed with unbuffered non-ECC memory; the motherboard must support registered ECC operation.

After installation, how can I confirm the module is running at 3200 MHz with CL22 timing?

Check the BIOS memory information or a system utility such as CPU-Z; it should report DDR4-3200, PC4-25600, and CAS latency 22.
