CPU Speed setup

Ë The FSB Speed of the VIA KT133A is 100MHz/133MHz.

	(Default)

The CPU speed must match with the frequency ratio. It will cause system hanging up if the frequency ratio is higher than that of CPU.

0AMD CPU Heat Sink Installation:

Beware: Please check that the heat sink is in good contact with the CPU before you turn on your system.

The poor contact will cause over heat, and might cause damage to your processor.

0Note: Please set the CPU host frequency in accordance with your processor’s specifications. We don’t recommend you to set the system bus frequency over the CPU’s specification because these specific bus frequencies are not the standard specifications for CPU, chipset and most of the peripherals. Whether your system can run under these specific bus frequencies properly will depend on your hardware configurations, including CPU, Chipsets, SDRAM, Cards….etc.
