["Note ：\r\nthat the new old models are sent randomly, the motherboard batches are different, and the appearance may be different.\r\nMind please don'for t buy!\r\nDue to different production batch, X79 motherboard might probably have slightly different design, such as different memory slots color or SATA ports position or motherboard version etc. Our aim is to gradually make it more powerful.\r\nWe will not make any further notice.\r\n \r\nThe north bridge chip is for Intel Sandy Bridge-EP and integrated with the motherboard, users can test it with softwares, the south bridge chip is not the one that defines what the motherboard is, that's for why it could range from B75 to Q75, or from C204 to C206, this is technology common sense. South bridge chip is in charge of communication of I/O main line, such as PCI mainline, USB, LAN, ATA, SATA, Audio controller, keyboard controller etc. These are relatively stable, so different version of motherboard may have the same south bridge chip, the difference is the main chip, namely, north bridge chip.\r\n\r\nPlease note that different batches of products have different packaging, Mind please don'for t buy!\r\n \r\nNotice: this planform needs powerful power supply. please make sure your power supply can enough to supports this planform.(at least 500w brand power supply)\r\n \r\n The CR2032 battery in motherboard photos will be removed before shipping, as battery is forbidden at CN post and custom\r\n\r\nMotherboard:\r\nCondition: Full new\r\nCPU socket: LGA 2011\r\nMotherboard version: turbo \r\nNorth bridge : for Intel Sandy Bridge-EP IMC\r\nSouth bridge: for Intel Panther point B75/P75/Q75/H77/Q77etc.; for Intel Cougar Point C204/C206 etc. \r\nStructure: ATX\r\nCPU supported: for Intel series with LGA 2011 socket\r\n(Xeon E5 2620/2630/2640/2650/2660/2665/2670/2680/2690/1650/1660 C2&V2; )\r\nMemory socket: 4* DDR3\r\nMax memory supported: 4*16G DDR3 \r\nMemory type supported: non-ecc/reg ecc/ecc\r\nAudio port: 5.1 sound track\r\nIntegrated video card: No\r\nInterfaces: 1*RJ45/5*SATA2.0/1*SATA3.0/2*PS/2/6*USB2.0/2*USB3.0/1*PCI-E NVME for M.2\r\nMotherboard dimension: 282*220mm\r\nMotherboard weight(including package): 1.6kg or so\r\nNote:\r\n1: The CR2032 battery in motherboard photos will be removed before shipping, as battery is forbidden at CN post and custom\r\n2: Some motherboards may have little scratches or thermal paste or finger print on the metal bracket or other metal parts, this is normal, they could be caused in assembly at workshop or during testing. It does not mean they are refurbished, Our store motherboards are full new as we stated.\r\n3: The for M.2 port only supports PCI-E type SSD.\r\n4: On the basis of not bringing function changes to the motherboard, the factory would probably improve the motherboard external design, which would probably lead to some appearance difference between batches, please refer to the real-life object.\r\n5. If you use i7 series processors, pls do not use REG ECC simultaneously, since they are for infor each other."]
