5. CPU Bus Clock (The CPU input clock)
ALi Aladdin V chipset can only support CPU Bus Clock up to 100MHz.
However, the clock generator of the P5F97 motherboard allows user to
change CPU Bus Clock from 60to120MHz. Over clock (105~120MHz)
may cause system intermittent lock up or fail to boot-up (no video).
times the “CPU Core to Bus Clock Multiplier”.
The CPU internal core clock is equal to the “CPU Bus Clock”
6. CPU Core and I/O Voltages
Two voltages Vcore and V
I
/o are required for Pentium class CPUs. The Vcore is used for CPU internal operation and
the V
I
/o is used to supply the voltage for external interface. The P5F97 motherboard has a jumper (JP2) which
connect between Vcore and V
I
/o. You need to short JP2 only when a Intel Pentium O.D.P. is installed.
