Targeted NAS Memory Upgrade

This 8 GB DDR4 SODIMM is built for ASUSTOR NAS models AS5402T, AS5404T, AS6702T, AS6704T and AS6706T. It suits owners of those systems who need extra capacity for multitasking or larger workloads. The module replaces the AS-8GD4 part directly.

Fits Single-Slot SO-DIMM Bays

The 260-pin unbuffered stick installs in the factory memory slot without tools or cables. It runs at the standard 1.2 V, so the existing power delivery handles it without changes. No heat spreader means it fits tight chassis clearance.

Steps Up From Lower-Capacity Modules

Swapping a 4 GB or smaller stick for this 8 GB unit adds headroom for concurrent apps and file operations. The jump is worthwhile when the NAS runs multiple services or containers. Builders needing ECC or registered DIMMs must choose a different product.

Questions about this item

How does the CL22 latency behave when the ASUSTOR NAS runs sustained workloads?

The module operates at DDR4 3200 with CL22 timing and 1.2 V, so latency stays at the rated specification during continuous use.

What is the thermal and acoustic impact of this SODIMM inside an ASUSTOR enclosure running all day?

The unbuffered 1Rx8 design has no heat spreader and draws only 1.2 V, adding negligible heat and no audible noise to the system.

Which ASUSTOR models must the buyer already own for this 8 GB DDR4 3200 SODIMM to be compatible?

It is validated for ASUSTOR AS5402T, AS5404T, AS6702T, AS6704T and AS6706T, replacing part number AS-8GD4.
