Description: and high quality Feature: Integrated chip sound card/card, Integrated RTL8111H gigabit nics,Audio integration 6 channel sound chip. Two electrical outlets, 8 needle, a 24 pin power interface. CPU support for routine LG2011-3 series models. Suggest two CPU usage is the CPU (for example: E5-2678 v3 * 2), if you can'for t ensure the same CPU, at least to ensure that the CPU core in the same series number (for example: E5-2678 v3 + E5-2680 v3), core for different CPU combination without display. X99 dual for theory support to the maximum amount of memory is 512 g = 64 g * 8. When using a CPU, must be installed in position ( 1), in the main memory and CPU power supply must also be connected to a main location ( 1), if this is not the for case will not be able to correctly identify and work. Motherboard only, other accessories demo in the picture are not included Warm Tips: Due to different production batches, there are slight differences in the appearance of different batches of motherboards, but it does not affect the use. It is recommended to use the same model CPU and server power supply, otherwise there will be incompatibility.
