10Gb dual-port server NIC

The BFKK 10Gb Dual RJ45 PCIe 3.0 x4 Network Card adds two 10 Gigabit Ethernet ports to a server or workstation through a PCI Express 3.0 x4 slot. It is built around the Intel X550-AT2 controller and targets administrators who need 10Gbase-T connectivity over copper cabling. The card fits both standard and low-profile chassis using the included brackets.

Passive cooling in a x4 slot

The adapter uses a passive heatsink on the Intel X550-AT2 chip, so it adds no fan noise to a rack or tower. Power is drawn solely from the PCI Express 3.0 x4 interface, which also accepts x8 and x16 slots. Typical operation stays within the slot’s rated envelope without auxiliary connectors.

Brackets and driver flexibility

Both a full-height and a low-profile bracket are supplied, letting the same card serve a 1U server or a full-tower workstation. Drivers are downloaded directly from Intel for Windows 7 through Server 2019, Linux distributions including RHEL 6 to 8 and Ubuntu 16 to 20, plus VMware ESXi 6 and 7. No management software or licence key is bundled.

Questions about this item

How do I install the BFKK 10Gb Dual RJ45 PCIe 3.0 x4 card in a low-profile chassis?

Insert the card into any PCIe x4, x8 or x16 slot, then swap the full-height bracket for the included low-profile bracket before securing it to the case. Download the driver from Intel’s website for your OS.

What cabling limits apply to the dual RJ45 ports on this X550-AT2 based NIC?

Category-6A cable supports the full 100 m (328 ft) distance; Category-6 cable is limited to 55 m (180 ft) for 10 Gbps operation.

Which component is likely to reach its thermal or power ceiling first during sustained 10 Gbps loads?

The Intel X550-AT2 controller is the primary heat source under continuous 10 Gbps traffic; ensure adequate case airflow over the card’s heatsink.
