Targeted NAS Memory Upgrade

This OWC 8GB DDR4 2666 CL19 ECC SODIMM is built for Synology Rackstation RS1221+ and RS1221RP+ units. It adds 8GB of 1Rx8 unbuffered memory running at 1.2V. The module follows JEDEC PC4-21300 specifications for reliable operation in compatible micro servers and NAS systems.

Verify Slot And Configuration

Confirm your Rackstation has a free 260-pin SODIMM slot before ordering. The existing memory must be DDR4 ECC unbuffered; mixing registered or non-ECC modules is not supported. This stick is backwards compatible with 2400MHz and 2133MHz bus speeds, so it will clock down automatically if the system runs at those frequencies.

Single Module For Capacity Expansion

Install this 260-pin SODIMM directly into the NAS motherboard slot; no heat spreader is fitted, so clearance is minimal. The upgrade increases total system memory for heavier workloads such as virtualisation or large file caches. It leaves any remaining slots available for further matched modules if the chassis supports them.

Questions sur cet article

Does the module ship with a heat spreader or any tools, or must those be bought separately?

The 260-pin SODIMM has no heat spreader and no tools are included; it installs directly into the slot.

Which capacity and rank should I choose for a Synology RS1221+ or RS1221RP+ upgrade?

This is a single 8 GB 1Rx8 ECC unbuffered module; add one or two to match the NAS's two slots.

What does the 2666 MHz rating deliver once the stick is installed in the NAS?

It runs at PC4-21300 CL19 1.2 V and will down-clock to 2400 MHz or 2133 MHz if the system requires it.
