This is an authentic Synology OEM memory module pulled from a DS1522+ after brief use during initial setup. It was replaced only to upgrade to a higher capacity and is in perfect working condition.

Technical Specifications: Model: D4ES02-8G Capacity: 8 GB Type: DDR4 ECC Unbuffered SODIMM (260-pin) Speed: 3200 MHz (PC4-25600) Latency: CL22 Voltage: 1.2V Rank: Single Rank (1Rx8)

Compatibility Note: While this is a standard SODIMM form factor (physically compatible with most DDR4 laptops), it is ECC Unbuffered memory. This module is specifically validated for Synology 22-series units and newer (e.g., DS1522+, DS923+, DS723+, RS422+). Using this genuine OEM module ensures system stability and prevents the "non-genuine memory" notifications within DiskStation Manager (DSM).

Please note: This will ship in anti-static packaging, but does not include the retail box as it was pre-installed hardware.
