A-Tech 4GB DDR4 2400MHz CL17 260-Pin SODIMM Synology D4NESO-2400-4G Laptop RAM

4GB DDR4 2400MHz SODIMM for Synology NAS

This 4GB DDR4 2400MHz CL17 SODIMM module is built as a direct replacement for the Synology D4NESO-2400-4G part. It suits owners of compatible Synology NAS units or DDR4 laptops who need a single 4GB stick to add capacity or replace a faulty module. The stick uses major-brand chips, runs at the standard 1.20V, and is unbuffered non-ECC with a 260-pin layout. Buyers who want more storage or require ECC registered memory should look elsewhere.

Simple slot-in install; verify model first

Installation is a straightforward slot-in process: power down the device, open the memory compartment, align the 260-pin key, and press until the latches click. The module operates at 1.20V with CL17 timing and requires no configuration in most systems. What usually goes wrong is ordering without confirming the exact Synology model supports DDR4 2400MHz SO-DIMM, or mixing this non-ECC stick with existing ECC memory in a system that expects ECC.

Check your Synology model and memory specs

Before ordering, verify that your Synology NAS or laptop officially supports DDR4 2400MHz (PC4-19200) unbuffered non-ECC SO-DIMM modules. Confirm the maximum supported capacity per slot and the total number of available slots. Ensure the system does not require ECC or registered memory, as this module provides neither. Cross-reference the Synology part number D4NESO-2400-4G with your device's compatibility list to avoid a mismatch.
