CPU Clock Frequency Selection In BIOS Setting.
There is a special function for CPU over-clocking requirement which can be chosen
and set by BIOS, please refer to the following steps for adjustment.
1. Enter the BIOS CMOS setup program.
2. Choose “Chipset Features Setup” in main menu.
3. Use “Page down” (or+) / “Page up (or -) to choose CPU clock frequency as one
of 66.8, 75, 83.3MHz or by JP3 to setting from 103MHz to 133MHz.
(Note: There are 66.8, 75 and 83.3MHz for pentium II CPU CLOCK frequency.
100, 103, 112 and 133MHz CPU clock are used for Deschutes CPU.)
4. Press “Save & Exit setup” to complete BIOS setting.
If screen becomes blank or system can’t boot anymore after above setting. that
means your CPU couldn’t be capable of supporting overclock, and you have to follow
the steps below to recover the CPU clock frequency.
Step 1: Power the system off. (J3 PW-ON)
Step 2: Press <INS> (Insert) key while powering on the system, system will function
with 66MHz external frequency at this moment which depends on what kind of
CPU on board.
Step 3: Please choose lower frequency and try again.
Warning:
We do not guarantee all CPUs can be over-clocked, it depends on CPU design and
the peripherals you are using; it’s vitally important to use faster peripherals (faster
SDRAM, I/O, AGP card...) to come with the higher CPU clock frequency.
Please set apporpriate CPU CLOCK frequency to make the system stable.
