Introduction of the BIOS
User defined external clock and multiplier factor:
User Defined:
When you choose the User Define, you will bw able to set the following five items.
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):
100MHz (1/3)
114MHz (1/3)
129MHz (1/4)
143MHz (1/4)
153MHz (1/4)
CPU bus speed above 100MHz/133MHz supported but not guaranteed due to the
PCI and chipset specs.
Multiplier Factor:
You can choose the following multiplier factors:
x2
x6.5
The default setting is x4.5.
L2 Cache Latency:
Sixteen setting are available, Default, and 1 to 15. This item can let you adjust the
processor L2 cache speed, the larger the value, the faster the L2 cache will run. You
