CPU Speed Setup

CPU Speed Setup

The system bus frequency can be switched at 66MHz, 100MHz, 133MHz and Auto by adjusting
JP10/JP11/JP26 (See Figure 1). The CPU Frequency is control by BIOS.

The CPU speed must match with the frequency RATIO. It will cause system hanging up

0000

if the frequency RATIO is higher than that of CPU.

Note: 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.
