OWC 8GB DDR4 2666 SODIMM for QNAP NAS

This 8GB DDR4 2666 CL19 module is built for QNAP TVS-672X, TVS-672XT, TVS-675, TVS-872X and TVS-872XT systems. It delivers a straightforward capacity boost for multi-app workloads, virtualization and file serving. The non-ECC unbuffered design matches the original specification for these NAS models.

Check 260-pin DDR4 slot availability and voltage

Your NAS must accept 260-pin DDR4 SODIMMs at 1.2V. Confirm the number of free slots and the maximum supported capacity per slot in the QNAP documentation. Existing modules should be non-ECC CL19 or compatible speeds such as 2400 or 2133 to avoid timing mismatches.

Fits single-slot upgrades

The single-rank 1Rx8 layout occupies one SODIMM socket, freeing remaining slots for future additions. JEDEC-standard operation requires no BIOS tuning. The low-profile stick clears standard NAS chassis lids and works alongside the original thermal solution.

商品問答

What comes in the box and do I need to buy anything else to install this 8GB DDR4 2666 CL19 SODIMM?

The package contains a single 8GB DDR4 2666 PC4-21300 CL19 1Rx8 260-pin 1.2V non-ECC SODIMM module. No extra parts or tools are required for installation.

Which capacity should I choose for my QNAP TVS-672X — this 8GB stick or a larger one?

This module provides 8GB of DDR4 2666 memory. Select the capacity that matches the total memory you want in your NAS and the number of slots available in your specific model.

What does the 2666MHz speed rating mean once the module is installed in my TVS-872XT?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency. It is backward compatible with 2400MHz and 2133MHz systems, so it will operate at the highest speed your NAS supports.
