Feature:1. Convenient and Practical: The mini PCI E Gigabit Ethernet card is a 1000base t Ethernet control card, which is backward compatible with 10/100base t networks. No drive, with LED indicator2. Chip and Transmission: The mini Ethernet card adopts the master control chip for Realtek RTL8111H, which supports high performance dual channel networking. The maximum data transmission speed in each direction is 1000Mbps (2000Mbps in total)3. Heat Sink and Bracket: The mini Ethernet card is equipped with low bracket and full height bracket, supporting standard and ultra thin computers and servers. Heat sink can effectively discharge excess heat4. Thickened Golden Pin: The mini Ethernet card uses the thickened golden finger connection to reduce hardware contact failures and avoid data packet loss and distortion5. System Support: The mini Ethernet card is applicable to for Win 7, for Win8, for Winx, and for Win 10, for Win Server 2008 R2, for Win Server 2012, for Win Server 2016, for Win Server 2019, for Linux 2.6.31 to 4.11.x.LTSSpecification:Item Type:Mini PCI E Gigabit Ethernet CardProduct Material:PCBBus Interface: MINI PCI ENetwork Interface: RJ 45Transmission Rate: 10/100/1000MbpsMain Control Chip: For Realtek RTL8111HFull Duplex and Half Duplex: Full Duplex and Half Duplex AdaptiveLED Indicator: LINK/ACT (connection operation)Applicable Model: Desktop ComputerCompatible Networks: for IEEE 802.3 10BASE T, IEEE802.3u 100BASE TX, IEEE802.3ab 1000BASE T IEEE802.3az Energy Efficient Ethernet, IEEE802.3x Flowing Control, 802.1q VLAN Tagging, 802.1p Layer 2 Priority EncodingDriver Support: For Win 7, for Win8, for Winx, and for Win 10, for Win Server 2008 R2, for Win Server 2012, for Win Server 2016, for Win Server 2019, for Linux 2.6.31 to 4.11.x.LTS.Package List:1 x Mini PCI E Gigabit Ethernet Card1 x Network Adapter Card1 x Baffle1 x Screw
