Exact Replacement for QNAP NAS

This 16GB DDR4 2666 CL19 ECC SODIMM matches the QNAP RAM-16GDR4ECT0-SO-2666 specification. It is built for laptops, all-in-one systems and NAS devices that require 260-pin unbuffered ECC memory at 1.2V.

Before Ordering Check

Confirm the target system accepts 260-pin DDR4 SO-DIMMs with ECC and unbuffered operation. Verify the motherboard or NAS firmware supports 2666MHz CL19 modules and 1.2V voltage. Ensure a free slot exists for a single 16GB stick.

Upgrade from Lower Capacity or Speed

Replaces 8GB or smaller DDR4 ECC modules and steps up from 2133MHz or 2400MHz sticks. The jump is worthwhile when the workload needs more simultaneous applications, larger file caches or ECC data integrity in a NAS or micro server.

Questions about this item

Does the 260-pin SODIMM arrive alone or with any tools or cables?

The module ships as a single 16 GB DDR4 2666 CL19 ECC SODIMM; no tools, cables or extra parts are included.

Should I pick this 16 GB CL19 stick or a different capacity or latency?

This is the only capacity and latency offered for the QNAP RAM-16GDR4ECT0-SO-2666 replacement; choose it when your NAS or laptop needs a single 16 GB ECC unbuffered module.

Will the 2666 MHz rating actually run at that speed in my QNAP NAS?

The module is JEDEC-standard DDR4 2666 (PC4-21300) and will operate at 2666 MHz if the system supports it; otherwise it down-clocks to 2400 MHz or 2133 MHz automatically.
