16GB DDR4 ECC UDIMM for Synology RS2418+

This 16GB DDR4 2666MHz ECC unbuffered DIMM is built for Synology RackStation RS2418+ and RS2418RP+ NAS units. It delivers 16GB capacity in a single 288-pin module with CL19 latency and 1.2V operation. The 2Rx8 organisation suits workloads that demand error-correcting memory for data integrity.

Check slot count and current population

Verify how many memory slots your RS2418+ or RS2418RP+ has free before ordering. The system accepts DDR4 2666, 2400 and 2133MHz ECC UDIMMs, so this module will clock down if existing sticks run slower. Confirm the chassis can be opened for DIMM access without voiding any service agreement you may hold.

Upgrade from 8GB or smaller modules

Replacing an 8GB stick with this 16GB module doubles per-slot capacity, letting you reach higher totals within the same slot count. The jump is worth it when virtual machines, Docker containers or large file caches push the NAS into swap. If your unit already runs at its maximum supported memory, this module adds no benefit.

商品問答

What comes in the box and do I need anything else to install it in my Synology RS2418+?

The box contains one 16GB DDR4 2666MHz ECC UDIMM module. No extra parts or tools are required for installation in the compatible NAS.

Should I choose this 16GB module or a different capacity for my RS2418RP+?

This single 16GB DIMM is the listed capacity; select it when you need to add 16GB to an available slot in the RS2418+ or RS2418RP+.

What does the 2666MHz rating actually deliver once the module is running in the NAS?

The module operates at 2666MHz CL19 with 1.2V ECC unbuffered signalling and will down-clock to 2400MHz or 2133MHz if the system requires it.
