Note
According to Celeron
®
PPGA MMX processor types, some Celeron
®
PPGA MMX
processors will have the multiplier factor locked and the signal disabled. In this
situation, there is no way to choose a higher multiplier factor.
✏
AGPCLK/CPUCLK:
The default setting is “ 2/3”. In this state, the AGP bus speed will be the CPU bus
speed divided by 3 and times 2. If you choose the setting to “ 1/1 ”, the AGP bus
speed will equal to the CPU bus speed.
✏
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
have to be aware that if you set the L2 cache speed too fast, it will cause the L2 cache
to fail. If the L2 cache fails it will cease to run until you reset the value, but the
processor and L1 cache will still function, just not as well. To make sure your L2
cache functions properly please choose an appropriate setting. The default setting is
Default.
✏
Speed Error Hold:
The default setting is “Disabled”. If you change the setting to “Enabled” when the
CPU speed setting is wrong, the system will hold.
Normally, we do not recommend that you use the “User Define” option to setup CPU
speed and multiplier factors This option is for setup of future CPUs whose
specifications are still unknown. The specifications of all present CPUs are included
in the default settings. Unless you are very familiar with all CPU parameters, it is
very easy to make mistakes when you define the external clock and the multiplier
factor by yourself.
Solution in case of booting problem due to invalid clock setup:
Normally, if the CPU clock setup is wrong, you will not be able to boot. In this case, turn the
system off then on again. The CPU will automatically use its standard parameters to boot.
You can then enter the BIOS Setup again and set up the CPU clock. If you can’t enter the
BIOS setup, you must try turning the system on a few times (3~4 times) or press
“INSERT“ key when turning on and the system will automatically use its standard
parameters to boot. You can then enter BIOS SETUP again and set up the new parameters.
