Generic 10G RJ45 Ethernet Module for Synology NAS

This 10G Ethernet module is a narrowly targeted upgrade part, built to add 10-gigabit RJ45 networking to compact Synology NAS units rather than to serve as a general-purpose network card. It pairs a PCIe 3.0 interface with the Marvell AQC113C controller, a chip well known in the 10GBASE-T space for driving full 10G speeds over ordinary copper cabling. The listing frames it specifically for models such as the DS923+, DS723+, RS422+, and DS1522+, which signals that this is a fit-for-purpose accessory aimed at owners of those systems who want to move beyond gigabit without switching to fiber.

Because it terminates in a standard RJ45 jack, the module slots into existing copper infrastructure, working with the Cat6 and Cat6a runs many home labs and small offices already have in place. That keeps the upgrade path simple: add the module, connect a 10G-capable switch or client, and the NAS gains a substantially faster link. The trade-off is context. Sold under the Generic brand, the module arrives without the documentation, support channel, or warranty assurances a name-brand part would carry, and the listing stays quiet on cooling, physical dimensions, and included hardware. For the specific Synology owners it names, it reads as a focused, affordable route to 10G; buyers outside that list should confirm fit before committing.
