Questions about this item

Will this 2666 MHz DDR4 SoDIMM run reliably in a QNAP NAS that currently uses slower DDR4 modules?

The module operates at 2666 MHz (PC4-21333) and will down-clock to match the slowest installed memory, so it works alongside existing DDR4 without instability.

How can I confirm the 4 GB stick is detected at the correct 2666 MHz speed after installation?

Check the NAS system information or BIOS memory report; it should show 4 GB of DDR4 running at 2666 MHz with a 260-pin SoDIMM form factor.

Does the package include only the RAM-4GDR4A0-SO-2666 module or are tools or brackets supplied?

Only the 4 GB DDR4 2666 MHz 260-pin SoDIMM module is included; no tools, brackets or additional cables are provided.
