## Summary description

The Synology D4ES02-4G is a 4 GB DDR4 ECC memory module designed for PC and server use. It features a 260-pin SO-DIMM form factor and ensures data integrity with ECC technology. This memory module enhances system performance and reliability, making it ideal for demanding applications.

## Long description

The Synology D4ES02-4G DDR4 4 GB SO-DIMM ECC memory module is a compact, industry-standard SO-DIMM designed for use in compatible PCs and servers. With 4 GB of DDR4 memory and error-correcting code (ECC) technology, this module helps maintain data integrity under sustained loads and reduces the risk of memory errors. Its 260-pin SO-DIMM form factor fits small-form-factor systems that require reliable, low-profile memory upgrades.
Advantages
ECC technology detects and corrects single-bit memory errors to improve system stability and reduce unexpected crashes in critical workloads. The DDR4 design provides lower voltage operation and improved bandwidth compared with previous memory generations, while the 260-pin SO-DIMM format is suitable for compact motherboards and space-constrained server modules. The 4 GB capacity offers a balance between modest memory expansion and compatibility with systems that accept single-module upgrades.
Suitable for
 Compact workstations and small-form-factor PCs that use 260-pin SO-DIMM slots
 Entry-level servers and network appliances requiring ECC memory for increased reliability
 Systems used for storage management, virtualization light workloads, and network services
Key specifications
 Capacity: 4 GB
 Memory type: DDR4
 Form factor: 260-pin SO-DIMM
 Error correction: ECC (Error-Correcting Code)
How to use
Before installation, power down the system and disconnect all power sources. Open the chassis to access the SO-DIMM slot, align the module with the 260-pin connector using the notch as a guide, and insert the module at the recommended angle until it clicks into place. Reassemble the chassis, reconnect power, and power on the system. Confirm that the system recognizes the new memory in the BIOS/UEFI or operating system memory reporting tools and verify ECC functionality if supported by the platform.
Usage recommendations
Install memory modules in matched pairs where the platform specifies dual-channel operation and verify motherboard or system vendor compatibility lists for supported memory types and maximum capacities. When replacing existing modules, handle the module by the edges, avoid static discharge by using proper grounding, and ensure the system firmware is up to date to support DDR4 ECC features.
