%%%% %%%% %%%% %%%%
The wrong settings of the multiplier and external clock in certain circumstances may
cause CPU damage. Setting the working frequency higher than the PCI chipset or
processor specs, may cause abnormal memory module functioning, system hangs,
hard disk drive data lose, abnormal functioning of the VGA card, or abnormal
functioning with other add-on cards. Using non-specification settings for your CPU is
not the intention of this explanation. These should be used for engineering testing, not
for normal applications.
If you use non-specification settings for normal operation, your system may not be
stable, and may effect system reliability. Also, we do not guarantee the stability and
compatibility for settings that are not within specification, and any damage of any
elements on the motherboard or peripherals, is not our responsibility.
Ext. Clock (PCI):
66MHz (1/2) ! ! ! ! default
68MHz (1/2)
107MHz (1/3)
133MHz (1/3)
140MHz (1/4)
If you want to change your CPU, be sure to first cut off the AC power of your
computer, don't attempt while computer is in "Shutdown" only mode. Furthermore,
you also need to use the CCMOS1 jumper to clear the CMOS after you change your
CPU (refer to section 2-4).
