Description It is suitable for converting the PCI-E slot on the PC side into 4 gigabit Ethernet RJ45 interfaces, and the gigabit network interface supports 10/100/1000M data rate.Using Realtek8111H chip solution, it has higher data transfer rate and lower consumption, as well as better stability and compatibility.The all-round super- plate heat sink design can effectively reduce the temperature of the chip quickly and avoid unstable data transmission due to high temperature and overheating.The PCle x1 interface is designed, and it also supports PCI X1, X4, X8, and X16 channels. Not suitable for PCI slots.Plug and play, fast data transfer rate and easy connection.Compliant with PCI Base Specification 2.0 (5GTs) and backward compatible with Specifications 1.1 and 1.0APCI Management Specification 1.2Support 10/100/1000 auto configurationSupport for swap/polarity/skew correction, detection and auto-correctionSupport for NDIS5, NDIS6 checksum offload (IPv4, IPv6, TCP, UDP) and split task, offload (bulk transfer v1 and bulk transfer v2)Supports EMAC-393 ECMA ProxZzzy host sleep standardSupports full duplex flow control (IEEE 802.3X)Supports 9K bytes jumbo framesFully compliant with IEEE 802.3, IEEE 802.3u, IEEE 802.Supports IEEE 802.1p layer 2 priority encoding (prioritization)Supports IEEE 802.1Q VLAN tagging (Virtual Local Area Network)Support IEEE 802.3az-2010 (EEE)Support down/drop saving/PHY disable modeSupports PCI message signaled interrupts ( and -X)Support quad-core receiver regulation (RSS)Support protocol offload function ( NS)Supports two 1- 2.5Gbps PCI busesSupport hardware error correction code (ECC) functionSupport hardware Cyclic Redundancy Check (CRC) functionSupported Operating Systems:Windows ME, 98SE, 2000, XP, Vista, 7 and 8 32-/64-bitWindows Server 2003, 2008 and 2012 32-/64-bitLinux, OS and DOSColour:blackMaterial:PCBSize:114x68.8mmPackage Contents:1 x Network Card1 x Short Iron Piece1 x Chinese And English ManualOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
