Server Memory Kit

This OWC kit supplies 128GB of DDR4 2133 ECC registered memory across four 32GB RDIMMs. It targets administrators upgrading Synology FS3017, FS2017 or RS18017xs+ NAS units and similar server or workstation platforms that require registered ECC modules.

Installation Notes

The 288-pin DIMMs seat in standard DDR4 RDIMM slots without tools, but the modules must not be mixed with unbuffered or load-reduced ECC memory. Systems that do not support registered ECC will not recognise the kit, so verify the platform manual before purchase.

Sustained Operation

Rated at 1.2V with CL15 timing, the modules meet JEDEC PC4-17000 specifications for continuous server workloads. Error-correcting code and registered buffering maintain data integrity during extended multi-threaded tasks such as virtualisation or large-volume file services.

商品問答

How do I verify the 128GB kit is running at DDR4 2133 CL15 with ECC registered after installation?

Check the BIOS or UEFI memory information screen; it should show 128GB total, 2133 MHz speed, CL15 latency, 1.2V voltage and ECC registered status for each of the four 32GB modules.

What comes in the box and what must be purchased separately?

The box contains four 32GB 288-pin DDR4 2133 ECC registered RDIMM modules (2Rx4, CL15, 1.2V); no additional parts or cables are required for installation in a compatible server or NAS.

Which capacity kit should I choose for a Synology FS3017, FS2017 or RS18017xs+?

This 128GB (4×32GB) kit matches the OEM RAMRG2133DDR4-32G specification and fills the four DIMM slots in those NAS models for the maximum supported capacity.
