32GB DDR4 ECC RDIMM module

This 32GB DDR4 2666 registered DIMM adds error-correcting memory capacity to compatible servers and NAS devices. The module operates at 1.20V with CL19 latency and uses a 2Rx4 organisation built from major OEM DRAM chips. It targets IT professionals who need reliable, tested memory for mission-critical workloads.

Verify DDR4 RDIMM slot and ECC support

Before ordering, confirm the host system accepts 288-pin DDR4 registered DIMMs and enables ECC functionality in the BIOS or firmware. The module is validated for QNAP NAS models referencing part number RAM-32GDR4ECK0-RD-2666, so cross-reference your hardware documentation for exact compatibility. Unbuffered or non-ECC platforms will not support this registered design.

Standard voltage and passive cooling

Running at the standard 1.20V DDR4 voltage, the module draws typical registered DIMM power without a heat spreader. Passive airflow in a properly ventilated chassis is sufficient for normal server or NAS operating temperatures. Acoustic output is limited to the system fans already present in the enclosure.

Questions about this item

What does the 32 GB module include and do I need anything else to install it?

The box contains a single 32 GB DDR4 2666 RDIMM. No extra parts are required; the module fits a standard 288-pin DDR4 slot.

Should I pick the 2Rx4 registered version or another variant for my QNAP NAS?

Choose the 2Rx4 registered ECC module (part MR21300-324K1) when your QNAP model specifies DDR4 2666 RDIMM memory.

What does the 2666 MHz rating mean once the DIMM is running in my server?

The memory operates at 2666 MT/s with CL19 latency at 1.2 V, delivering the rated DDR4 2666 throughput for supported platforms.
