Know before you buy
This specific module is engineered for the Synology RS2418RP+ and RS2418+ models. While it may physically fit other systems, we recommend verifying your specific NAS model's memory requirements in your user manual to ensure full compatibility.
Non-ECC (Error Correction Code) UDIMM is standard consumer-grade memory. It is designed for efficient, high-speed data processing in environments where advanced error correction is not required by the system architecture.
Yes, you can typically mix this module with existing RAM, provided the total capacity does not exceed your NAS model's maximum supported memory limit. For the best stability, ensure the new module matches the speed and voltage specifications of your current hardware.
Generally, upgrading user-accessible memory does not void your manufacturer warranty. However, it is always a good practice to consult your specific Synology warranty terms regarding hardware modifications.
The 2666MHz speed allows for faster data transfer rates between the memory and the processor. This helps reduce latency during heavy multitasking and improves the overall responsiveness of your NAS when running multiple applications or services simultaneously.
