1. Processor Support –
One of most important decisions made by anyone choosing or building a new PC in which
processor is desired. Motherboard, in particular chipset, decides what type, speed and even
what number of processors to use on motherboard. Processor support functions of the.

2. L2 Cache Support –
North Bridge of chipset contains cache controller circuitry to control functioning of Level 2
(L2) cache. Cache buffers recent memory accesses by processor, which improves
performance drastically since it operates much faster than system memory.

3. Main Memory Support –
As a memory controller, North Bridge links processor to memory system logically and
electronically, establishes main memory and cache architectures, and assures the reliability
of data stored in RAM chips. As there are different kinds of memory and different speeds
of RAM chips, a North Bridge chip supports a specific type of RAM at specific speeds.

4. Maximum Memory Support –
The chipset dictates maximum amount of RAM possible on the motherboard.

5. DRAM Support –
North Bridge decides type of memory motherboard can use. Changing memory type
impacts way that memory is read and written to, which is controlled by chipset. Moreover,
some chipsets are better than others with certain types of memory, i.e. a chipset can be
optimized to provide faster access to a certain kind of memory, while being less efficient in
using a different type of memory.

6. AGP functionality –
North Bridge also determines AGP functionality on motherboard. Some chipsets have
integrated video, while others support AGP slot on motherboard. AGP slot is used to house
video card. AGP is essential for high performance graphics cards.
