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
