Description Description: COMPATIBLE WITH OSCompatible with Windows 10 / 11, Linux kernel up to 5.6 operating systems.DRIVER INSTALLATION REQUIREDTo find more OS compatibility version or driver download.2.5GBPS PCIE NETWORK ADAPTERPCIe 2.5G 4-Speed Multi-Gigabit Network Adapter supports data rate up to 2.5 Gbps. It will increase business working efficiency by increasing the network speed. The transmission is more stable, and it is not easy to cause packet loss and distortion.ADD 2.5G RJ45 ETHERNET PORTFits any PCI Express x1, x2, x4, x8 or x16 socket. NOTE: Only work with PCI-E slot, Not for PCI Slot.PACKAGE CONTENTS2.5G PCIe network card, standard bracket, low-profile bracket, screwdriver, screws, CD Drive.2.5Gbps Network SpeedUp to 2.5 times faster data transfer speed, using next-generation 2.5GBase-T technology, faster than standard Gigabit Ethernet, better for large-scale games and complex task processing, providing a better experience for desktop computers. High Performance ChipRLihm 2.5GBase-T pci express network card adopts Intel I226-V chip, which is stable and fast, and performs well in large-scale games and complex multitasking. The 2.5 gb ethernet card auto-negotiates between high-speed and low-speed connections, automatically adapting to the connected network device. Heatsinks and BracketsThe pci express network card comes with standard brackets and low profile brackets, suitable for desktop and small/slim computers/servers; to improve usage stability and cool down quickly, our network cards are equipped with heat sinks. OS SupportRLihm network card for pc is fully compatible with Windows 10/11 and Linux to meet more of your needs. Full CompatibilityThis pc network card is compatible with PCIE-1, PCIE-4, PCIE-8 and PCIE-16 slots and is compliant with IEEE 802.3, IEEE 802.3u, IEEE 802.3ab, IEEE 802.3az, IEEE 802.3bz. Pay AttentionThe I226-V chipset is not suitable for server CPUs below the sixth generation, please check if it is compatible with your computer before placing an order.
