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.

M 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.

Figure 1

ÖIf the CPU FSB is 133 FSB, the frequency of the SDRAM can be determined by SDRAM’s SPD or setting in BIOS.

M If JP10, JP11, JP25 is not present, FSB will be determined automatically. If these 3 jumpers are available, you can choose at 66MHz, 100MHz, 133MHz and Auto.

M 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

CPU Speed Setup

your system can run under these specific bus frequencies properly will depend

on your hardware configurations, including CPU, Chipsets, SDRAM, Cards….etc.
