OWC 16GB DDR4 ECC UDIMM for Synology FS2500

This 16GB DDR4 2666 ECC unbuffered UDIMM is built specifically for the Synology FlashStation FS2500. It adds 16GB of error-correcting memory to the NAS, helping maintain data integrity during intensive workloads. The module suits administrators who need a validated upgrade for this exact platform.

Fits FS2500 DDR4 slots with 288-pin layout

The stick plugs into a standard 288-pin DDR4 DIMM slot on the FS2500 motherboard. It runs at 1.2V and carries a 2Rx8 organisation, matching the system's native electrical and timing requirements. Because it is unbuffered ECC, it works without registered memory support. Backward compatibility with 2133MHz and 2400MHz buses allows the module to down-clock if the platform demands it.

Single-module upgrade with lifetime warranty

The package contains one 16GB DIMM, so capacity scales in 16GB increments per populated slot. OWC validates every module in-house and backs it with a limited lifetime warranty plus free technical support. JEDEC and RoHS compliance ensures the upgrade keeps the original system warranty intact. No heat spreader is fitted, preserving clearance in dense NAS chassis.

商品問答

How does the 2Rx8 dual-rank layout affect sustained throughput on the FS2500?

The dual-rank 2Rx8 organisation lets the memory controller interleave accesses across both ranks, which keeps bandwidth higher during long workloads than a single-rank module of the same capacity.

What thermal headroom should I expect from the 1.2 V unbuffered DIMM running 24/7 in a rack?

At 1.2 V with no heat spreader the module runs cool enough for continuous operation in a Synology FS2500 chassis; airflow from the system fans is sufficient — no extra cooling is required.

Which existing DIMM slots must be free on the FlashStation FS2500 to install this 288-pin module?

The FS2500 uses standard 288-pin DDR4 UDIMM slots; you need one vacant slot that supports ECC unbuffered memory at 2666 MT/s (PC4-21300) to add this 16 GB stick.
