Server ECC Registered DDR4 Kit

This 64GB kit contains two 32GB DDR4 2133MHz registered DIMMs built for servers, workstations and compatible NAS units such as the FS3017, FS2017 and RS18017xs+. It delivers ECC error correction and registered buffering for data integrity in multi-module configurations.

DDR4 2133 Registered Limitations

The modules operate at 2133MHz with CL15 latency and 1.2V, conforming to the PC4-17000 JEDEC standard. Registered ECC memory cannot be mixed with unbuffered or load-reduced DIMMs and will not function in standard desktop platforms that lack registered memory support.

Build and Connector Implications

Each stick uses a 288-pin DDR4 form factor without a heat spreader, keeping the profile low for dense server chassis. The dual-rank 2Rx4 organisation fits two modules per channel, and the JEDEC-compliant build ensures warranty-safe upgrades in qualified OEM systems.

商品問答

Should I choose the 64 GB dual-channel kit or a single 32 GB module?

The 64 GB kit provides two 32 GB modules that run in dual-channel mode, doubling memory bandwidth compared with a single stick.

What does the 2133 MHz speed mean for my NAS or server?

The modules operate at 2133 MHz with CL15 latency, delivering up to 17 GB/s of theoretical bandwidth per channel.

Will the 288-pin DDR4 registered ECC interface work in my Synology FS3017?

Yes, the 288-pin DDR4 registered ECC design matches the FS3017, FS2017 and RS18017xs+ memory slots exactly.
