Targeted QNAP NAS Memory Upgrade

This 4GB DDR3 SODIMM is built for QNAP TS-1270U-RP, TS-470U, TS-470U-RP, TS-470U-SP and TS-670U systems. It suits administrators who need a validated module to expand capacity in these specific rackmount or tower NAS units. Buyers requiring ECC protection or capacities beyond a single 4GB stick should look elsewhere.

DDR3 1333 Interface Constraints

The module runs at PC3-10600 1333MHz with CL9 latency on the DDR3 standard. Speed is fixed by the JEDEC specification; the memory will not negotiate a higher data rate even if the platform supports faster DDR3 grades. Systems limited to lower DDR3 speeds will downclock the module automatically.

Unbuffered SODIMM Build and Fit

A 204-pin unbuffered non-ECC stick without a heat spreader keeps the profile low for tight NAS slots. The 1.5V operation matches the DDR3 baseline, so no voltage adjustment is needed. Installers should confirm the chassis provides SODIMM access before opening the unit.

Questions about this item

Should I pick the 4GB module or add multiple sticks for my QNAP TS-470U?

The module is a single 4GB stick; add one per available SODIMM slot to reach the capacity your NAS supports.

What does the 1333MHz rating deliver inside a TS-670U?

It runs at DDR3 1333 (PC3-10600) with CL9 latency, giving the rated bandwidth the QNAP memory controller expects.

Will the 204-pin DDR3 SODIMM fit the TS-1270U-RP memory slots?

Yes — the 204-pin DDR3 SODIMM form factor matches the slots used in the listed QNAP models.
