Synology RS3621RPxs and RS3621xs+ memory upgrade
This 16GB DDR4 ECC UDIMM is validated for Synology RackStation RS3621RPxs and RS3621xs+ systems. It installs as a single module to expand NAS memory capacity. Buyers needing higher-density kits or registered DIMMs for other platforms should verify their hardware requirements first.
DDR4 2666 CL19 ECC unbuffered specification
The module runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.2V. It uses a 2Rx8 288-pin unbuffered layout with on-die error correction. Systems that require registered or load-reduced memory cannot use this part.
JEDEC standard compliance and backward speed support
The DIMM meets JEDEC and RoHS standards for warranty-safe installation. It also operates at 2133MHz and 2400MHz when the host platform dictates lower speeds. No heat spreader is included, so airflow in the chassis must be adequate.

Questions sur cet article
What does the 2666MHz speed mean for my Synology RS3621RPxs or RS3621xs+ NAS?
The module runs at 2666MHz, matching the native memory controller speed of the RS3621RPxs and RS3621xs+ so the system operates at its rated bandwidth without downclocking.
How does the PC4-21300 designation relate to the DDR4 2666MHz interface in practice?
PC4-21300 is the JEDEC standard name for DDR4 2666MHz; the module plugs into the 288-pin UDIMM slots and will also run at 2133MHz or 2400MHz if the system requires a lower speed.
Will this 288-pin UDIMM fit the memory slots in my RS3621RPxs or RS3621xs+?
Yes, it is a standard 288-pin DDR4 ECC UDIMM, the exact form factor used by the RS3621RPxs and RS3621xs+ for memory expansion.
