System-Specific DDR3 SODIMM

This 8 GB DDR3 1600 CL11 module uses the 204-pin SODIMM form factor and runs at 1.5 V. It is built to JEDEC PC3-12800 specifications and carries OWC part number 1S6D32R808GB for verified compatibility.

For QNAP NAS owners

The stick is validated for QNAP IS-400 Pro, TVS-471, TVS-671 and TVS-871 units needing a single 8 GB upgrade. Buyers who need ECC protection, registered DIMMs or capacities beyond 8 GB per slot should look at something else.

Simple slot insertion

Installation means opening the NAS chassis, aligning the keyed SODIMM and pressing until the side clips engage. The most common issue is mixing this unbuffered non-ECC module with existing ECC or registered memory, which prevents the system from posting.
