SMUGDESK PCIe 2.0 x4 10GBASE-T RJ45 Network Card

SKU CH-YXAX-SRQ2N

Adds a single RJ45 port running at 10G, 2.5G, 1G, 100Mbps over Cat6a or Cat5e via PCIe 2.0 x4 with LACP, 9000MTU jumbo frames and passive cooling

  • Single RJ45 auto-negotiates five speeds up to 10G
  • PCIe 2.0 x4 fits x4, x8 and x16 slots
  • LACP aggregation and TCP offload reduce CPU load
  • 9000 MTU jumbo frames boost NAS and routing throughput
  • Passive cooling ensures stable long-term operation

PCIe 2.0 x4 10GBASE-T NIC

This SMUGDESK network card adds a single RJ45 port that auto-negotiates five speeds up to 10 Gbps. It fits PCIe 2.0 x4, x8 or x16 slots in desktop PCs and rack servers. Passive cooling keeps the adapter stable during continuous operation.

Upgrading from gigabit bottlenecks

The card replaces a standard 1 Gbps link when moving large datasets to a NAS or between workstations. The jump is worth it when your cabling supports 2.5 Gbps or higher and the host platform has a free PCIe 2.0 x4 lane. Buyers staying on older Cat5e runs limited to 1 Gbps will not see the full benefit.

PCIe 2.0 x4 bandwidth ceiling

The four-lane gen 2 interface caps theoretical throughput at 16 Gbps, leaving headroom for 10 Gbps line rate plus protocol overhead. Jumbo frames up to 9000 MTU reduce CPU interrupts on heavy transfers. Systems limited to x1 slots or PCIe 1.1 cannot saturate the 10 Gbps port.

Highlights

  • Single RJ45 auto-negotiates five speeds up to 10G
  • PCIe 2.0 x4 fits x4, x8 and x16 slots
  • LACP aggregation and TCP offload reduce CPU load
  • 9000 MTU jumbo frames boost NAS and routing throughput
  • Passive cooling ensures stable long-term operation

Questions about this item

What PCIe slot size and generation does the card need?

The card fits any PCIe 2.0 x4, x8 or x16 slot on a desktop or rack-mount server motherboard.

Which driver step is often missed during Windows or Linux installation?

After seating the card, install the vendor driver before configuring link aggregation or jumbo frames; the OS generic driver will not expose those features.

What cabling and switch ports are required to maintain 10 Gbps over time?

Use Cat6a or Cat5e cables and connect to switch ports that also negotiate 10GBASE-T; dust the passive heatsink occasionally to avoid thermal throttling.
