4GB DDR4 2133MHz SODIMM for Synology

This 4GB DDR4 2133MHz CL15 SODIMM module is built as a direct replacement for the Synology D4NS2133-4G. It uses 260-pin DDR4 technology at 1.2V and is suited to laptops, notebooks, or all-in-one systems that accept a single non-ECC unbuffered stick.

Ideal for Synology NAS upgrades.

The module fits Synology units that specify the D4NS2133-4G part and works with AMD and Intel platforms that support standard DDR4 SO-DIMM memory. Buyers whose systems require ECC error correction or registered buffering should look elsewhere, as this stick provides neither feature.

2133MHz DDR4 speed rating

The decisive specification is the DDR4 2133 (PC4-17000) speed grade. Your motherboard or NAS must list DDR4 2133MHz support; a platform that only runs at a different DDR4 data rate will not operate correctly with this module.

商品問答

What motherboard slot is required for this 260-pin DDR4 SO-DIMM?

This module fits a standard 260-pin DDR4 SO-DIMM slot found in compatible laptops, notebooks, or all-in-one systems.

Will this CL15 1.20V module run stably alongside existing DDR4 2133 memory?

Yes, it operates at DDR4 2133 (PC4-17000) with CL15 latency and 1.20V, matching the JEDEC baseline for that speed so it will sync with identical-spec modules.

How can I confirm the system recognises the full 4GB after installation?

Check the BIOS/UEFI memory summary or the OS task manager; both should report the additional 4GB at 2133 MHz.
