Compatible QNAP NAS models

This 8GB DDR3L SODIMM is built for QNAP IS-453S, TS-1263U, TS-1263U-RP, TS-231P3 and TS-431P3 systems. It replaces the QNAP RAM-8GDR3L-SO-1600 part and suits owners who need a single-module capacity increase.

Sustained load behaviour

The module runs at 1600MHz with CL11 latency and 1.35V operation. Non-ECC unbuffered design handles typical NAS workloads such as file serving and light virtualization. JEDEC compliance ensures stable timing during extended uptime.

Installation notes

The 204-pin SO-DIMM fits the memory slot in the listed QNAP units. Installation is a straightforward DIY step; align the notch and press until the side clips lock. Common issues include mixing with existing modules of different speed or rank, which can prevent boot.

Questions about this item

How much power does the 1.35V DDR3L 1600 module draw when the NAS runs continuously?

The module operates at 1.35V, the standard DDR3L voltage, which reduces power draw and heat compared to 1.5V DDR3.

What must the QNAP unit already have for this 204-pin SODIMM to fit and work?

A free 204-pin DDR3L SODIMM slot and a motherboard that accepts non-ECC unbuffered memory at PC3L-12800 CL11.

Will this 8GB 2Rx8 stick work alongside the original 4GB module in a TS-231P3?

Yes, it is compatible with the TS-231P3; mixing capacities is supported, though matched pairs give best performance.
