The OWC 1S8T31R804GB is a 4GB DDR3L-1866, 1.35V laptop SODIMM memory module for users upgrading compatible Synology NAS models DS218+, DS418play, DS620slim, DS718+, or DS918+.
Recommended For
- Owners of a listed Synology NAS who see memory pressure while running several DSM packages or Docker containers can use this 4GB module as a memory-capacity upgrade; check the NAS model’s memory requirements before installing.
- DS918+ users running Plex alongside tools such as download managers and media-library services may find the extra memory useful when those concurrent tasks are pushing the NAS’s available RAM.
- Owners of the listed Synology models seeking a 4GB, 204-pin DDR3L SODIMM replacement can consider this module when matching the NAS’s memory requirements and configuration.
- Home-server users adding a few lightweight services to a compatible NAS may value the extra RAM headroom, provided their workload is limited by memory rather than the NAS’s processor or other hardware.
Real-World Use Scenarios
- Running several Docker containers—such as home-automation, media-management, or document services—alongside normal NAS tasks can use the extra memory as breathing room when the system is memory-constrained. It does not make the NAS processor or disk transfers faster.
- Running a lightweight virtual machine alongside DSM and NAS services can leave more memory available for the host system. The added RAM provides capacity, but does not guarantee that a particular VM will run smoothly; its workload and memory allocation matter.
- On a DS620slim used for Synology Photos, expanding memory can meet the 4 GB minimum Synology lists for object recognition. This is a specific feature requirement, not a promise that every Photos task will become faster.
- Using Surveillance Station while other NAS applications are active can make additional memory useful when the system is running short of RAM. It can provide more working room for concurrent services, but does not increase camera capacity by itself.
