Primary PCIe slot
Their are two bridge found in motherboard the north bridge and the south bridge. North bridge found near the CPU and south bridge found near the BIOS.
north and south bridge of a motherboard
north bridge
I am assuming you mean North Bridge\ South bridge North Bridge is the Memory Controller, that transfers data and instructions between the CPU ,RAM and PCIe Devices. South Bridge is the Storage Controller that controls how data is transferred onto Storage Devices(Hard drives)
the buss the north bridge chip the south bridge chip
By the north and south bridge.
North bridge connects the processor, memory and video card. South bridge connects all the peripherals whether it is connected using USB, ISA, and PCI connector. Note. South Bridge is also connected to north bridge
the sandy bridge chipset uses a single chipset housing
If you have North and South Bridge on your computer it will be all you will need not no more then 2 Bridges r VERY POWERFUL chipsets it will speed your computer up tremendously compairing to no bridges on your motherboard... tecnickly easyest way of explaning the way it works and all is: Processor is your Engine - RAM is your Gas - HardDrive is your cargo - North Bridge and South Bridge is your High Way... some computer may have just a north or south bridge some have both... North Bridge: does all the work to and from RAM to Processor RAM goes to and from Harddrive and processor ... to and from North to South bridge directly SouthBridge: does the PCI slots and Graphics Chipset when there is info goin through your Graphics card starts with : Harddrive to RAM to Processor to North Bridge to South Bridge to Graphics Chipset and back up to your Processor and RAM same way it came in... for some computers it works like that some dont there are deffrent ways how other computers work but if u have a single North bridge it will do all the work that ur South bridge dont. hope this helps out :)
it gets hot because it is constantly working and the high speed memory usage makes it hot.
The Nehalem chipset connects directly to the processor rather than to the North Bridge.
