16GB DDR4 ECC UDIMM for NAS

This 16 GB DDR4 ECC UDIMM module runs at 3200 MT/s with CL22 latency and 1.2 V operation. It uses a 288-pin unbuffered design built with major OEM chips. The single 16 GB stick targets QNAP NAS devices and compatible server motherboards that require ECC memory.

Replaces non-ECC or slower DDR4 modules

The jump is worth it when data integrity matters for file services, virtualization or backup workloads on supported QNAP NAS units. Systems running standard unbuffered DDR4 without error correction gain protection against silent data corruption. Builders filling empty slots on qualified platforms see immediate capacity gains.

Sustained load behaviour without heat spreader

Modules are stress tested under load to verify stability during extended operations. The bare PCB relies on chassis airflow for cooling during continuous NAS workloads. Unbuffered topology keeps latency low for steady-state throughput. ECC function operates continuously without performance penalty during long-running tasks.

Questions about this item

Will the 288-pin DDR4 ECC UDIMM fit my QNAP NAS memory slot?

Yes, the 288-pin DDR4 ECC UDIMM matches the standard slot used by compatible QNAP NAS devices such as the RAM-16GDR4ECT0-UD-3200.

Do I need to configure anything in BIOS after inserting the 16GB CL22 1.2V module?

The module runs at DDR4 3200 CL22 1.20V by JEDEC defaults, so most systems apply the correct settings automatically without manual changes.

How long will the Samsung Micron Hynix chips on this 2Rx8 stick last under heavy NAS workloads?

The major OEM DRAM chips are stress-tested under load and covered by a lifetime replacement warranty for the original purchaser.
