The North Bridge Chip (Northbridge) is the most important component of the motherboard chipset, which is the closest chip on the motherboard to the CPU, which is responsible for contacting the CPU and controlling memory, by establishing a communication interface between the processor and the PCI bus, DRAM, AGP, and L2 cache.
North Bridge Chip function
North Bridge Chip is responsible for the connection with the CPU and control of memory AGP data in the North Bridge internal transmission, to provide the type and frequency of the CPU, the system's front-end bus frequencies, memory type and maximum capacity, AGP slots, ECC error correction and other support, integrated chipset of North Bridge chip also integrated the display core. North Bridge played a very obvious role in the computer plays a leading role, so people used to be called the main span (Host bridges).
North Bridge Chip features
North Bridge Chip is the motherboard on the latest chip from the CPU, this is mainly considering the North Bridge chip and processor communication between the most closely, in order to improve communication performance and shorten the transmission distance. Because the North Bridge chip data processing volume is very large, calorific value is more and more, so now the North Bridge chip is covered with the radiator to strengthen the North bridge chip cooling, some of the motherboard of the North Bridge chip will also be coupled with the fan cooling.
