Synology NAS Memory Upgrade

This 4 GB DDR3 SODIMM is built for Synology RackStation and DiskStation units that accept PC3-12800 unbuffered non-ECC modules. It targets administrators who need a straightforward capacity increase for file serving, backup or virtualization tasks. The 204-pin form factor fits the standard laptop-style slots used in these NAS appliances.

Sustained Load Behaviour

Rated at DDR3 1600 with CL11 timing, the module operates at 1.35 V to reduce heat during continuous operation. Major OEM chips from Samsung, Micron or Hynix are stress-tested under load before shipping, supporting stability during long RAID rebuilds, heavy multi-user access or overnight backup windows. The 2Rx8 organisation helps maintain throughput when the memory controller interleaves across ranks.

Build and Connectors

The bare green PCB has no heat spreader, keeping the profile low for tight NAS chassis where adjacent slots or drive cages leave little clearance. Gold-edge contacts on the 204-pin interface resist oxidation in always-on environments. Installation follows the usual SODIMM latch mechanism, so most administrators can complete the upgrade in minutes without tools.
