Soyo SY-7ISA+ Motherboard User Manual

CPU Frequency Settings:  JP6, JP7, CJ1 and CJ2

For certain Intel CPUs, the multiplier is not locked such that setting a

multiplier higher than specified on the CPU is possible. For technical

details read the following:

Your FC-PGA 133/100/66 MHz FSB CPU has a pin JP6, JP7 to tell it

what FSB frequency the CPU requires; If these two jumpers are shorted

the motherboard will automatically run at the frequency the CPU was

specified to run at.

However, the FSB Frequency can also be set through jumpers CJ1 and CJ2

and it may therefore differ from the Frequency the CPU specifies. If CJ1

and CJ2 are to be used, JP6 & JP7 must be open. Doing so may however

force your CPU to operate out of its specifications and therefore SOYO

can not guarantee the proper functioning of your system.
