SO-DIMM 8 GB DDR4- , memoria D4ES02-8G, Serie 22 (DS3622xs+, DS2422+, DS1522+)

The Synology DDR4 8GB 260-pin SO-DIMM ECC memory module provides 8 GB of DDR4 system memory in a compact 260-pin SO-DIMM form factor. Engineered to work with compatible desktop and server platforms, this module uses ECC (Error-Correcting Code) technology to detect and correct single-bit memory errors, helping maintain data integrity and system stability under sustained loads. It is intended for environments where reliable memory operation is important and where a SO-DIMM profile is required.

Advantages

This ECC memory module offers error detection and correction that reduces the risk of data corruption, increasing uptime and reliability for critical tasks. The DDR4 architecture delivers improved bandwidth and lower power consumption compared with previous generations, while the 260-pin SO-DIMM format ensures compatibility with systems that accept small-outline DIMMs. The 8 GB capacity balances performance and resource efficiency for multi-tasking and memory-dependent applications.

Suitable for

• Compact servers and network-attached storage appliances that accept SO-DIMM DDR4 modules
• Workstations or small form factor PCs requiring ECC memory for improved data integrity
• Virtualization hosts and database systems with moderate memory requirements
• Applications where error correction and steady operation are preferred over maximum capacity per module

Key specifications

• Capacity: 8 GB
• Memory type: DDR4
• Form factor: 260-pin SO-DIMM
• Error correction: ECC (Error-Correcting Code)

How to use

Power down the system and disconnect it from the power source before installing the memory module. Open the system or module bay according to the manufacturer’s service instructions to access the SO-DIMM socket. Align the notch on the module with the socket key and insert at the recommended angle, then press down until the retention clips engage. After installation, close the chassis, reconnect power, and start the system. Verify that the system recognizes the new memory and that ECC reporting (if supported by the platform) indicates normal operation.

Recommendations

The module is best used in systems explicitly supporting DDR4 SO-DIMM ECC memory; check motherboard or device compatibility lists and firmware requirements. For multi-module configurations, install modules in matched pairs or according to the system vendor’s memory population guidelines. Keep electrostatic discharge precautions when handling the module and ensure firmware and BIOS/UEFI are up to date to enable optimal memory stability and ECC functionality.
