1. The design of all-board all-solid capacitors is more stable and durable than ordinary capacitors.2. Gigabit network card: RTL8111H Gigabit network card, dual indicator design, stable and fast, support diskless boot3. DDR3 memory, supports normal memory and RECC server memory, but cannot be mixed at the same time4. NVME PCIE 3.0 X4-channel M.2 high-speed hard disk, 2280 theoretical bandwidth can reach 6GB/S, does not support M.2 hard disk with NGFF interface SATA channel5. Easy installation: This product is very easy to install, no additional tools are needed, and the installation process is very convenient.Product name: X79 motherboardCPU:LGA1356CPU type:Zhiqiang series and i7 seriesMemory socket: 2*DDR3Max memory supported: 2*16G DDR3Memory type supported: 800/1280/1333/1600/1866mhz(Server memory and normal memory cannot be used at the same time, it has the compability problem.)Expansion slot:1*PCI-E X16 graphics slot1*PCI-E X1 slot1*USB2.0 slot (1 group)1*USB3.0 interface (speed 2.0)2*SATA3 interface2*SATA2 interfaceI/O interface:PS/2 interfacePS/2 keyboard and mouse universal interface1*RJ45 network interface6*USB2.0 interfaceAudio interfaceOther parameters: one 8-pin power jack (if it is connected to the middle of the board when only 4-pin is connected), one 24-pin power interface has 4 power supply modesDue to different production batches, there will be some differences in appearance, which will not affect the usecolour:BlackMaterial:PCB+metalsize:215 x 170mmPackage Contents:1 x X79 motherboard1 x E5 2420 V2 CPU2 x 4GB DDR3 memory
