The Motherboard

Essentials components in Mobo

• The more important part in a mobo is the chipset.

• It make the interconnexions between all the other parts on the mobo.

Mobo exemple :

The Nvidia Nforce4

• It’s the best chipset for AMD K8 CPU.

The mobo overclocking

• One frequency : the HT

• CPU clock = HT * Coef

• Ram clock = Cpu clock / Coef

• LinkHT = HT*coef

Overclocking exemple

• CPU 3000+ => 9*200 = 1800Mhz

• Ram = 1800 / 9 = 200Mhz

• LinkHT = 200*5 = 1000Mhz

• CPU = 9*312 = 2800Mhz

• Ram = 2800/10 = 280Mhz

• LinkHT = 312*3 = 936Mhz
