16GB DDR4 3200 ECC DIMM

This 16GB DDR4 module runs at 3200 MT/s with CL22 latency and 1.2V operation. It is an unbuffered ECC DIMM built for select workstations, servers and NAS systems. The 2Rx8 organisation and 288-pin form factor follow JEDEC standards for broad platform compatibility. No heat spreader is fitted, keeping the profile very low.

Sustained-load behaviour

JEDEC compliance means the rated 3200 speed and CL22 timings are maintained during continuous operation rather than only in short bursts. ECC circuitry detects and corrects single-bit errors on the fly, preserving data integrity in long-running server and NAS workloads. The 1.2V supply remains stable without elevated voltage headroom. Dual-rank density supports consistent throughput across extended sessions.

Thermals, noise and power

With no heat spreader or active cooling, the module runs silently and relies on chassis airflow for thermal management. At 1.2V the power draw per stick is modest, reducing aggregate load on the system power supply. The very-low-profile height avoids obstructing CPU cooler fans or airflow paths in dense server enclosures. JEDEC-standard construction ensures reliable operation within normal case temperatures.

Questions about this item

Will this 16 GB DDR4 3200 module fit a standard 288-pin DIMM slot on my workstation motherboard?

Yes, the module uses the industry-standard 288-pin DDR4 DIMM form factor, so it installs in any desktop or workstation board that accepts unbuffered DDR4 memory.

My server requires ECC memory — does this stick provide error-correcting code functionality?

The module is built with ECC support, allowing the system to detect and correct single-bit errors for improved data integrity in servers and NAS devices.

Can I mix this OWC module with existing RAM from another brand?

For best stability, populate all slots with identical capacity, speed and manufacturer modules; mixing different kits may force the system to run at lower speeds or cause instability.
