Introduction of BIOS 3-5
Note 2: "S" means this frequency implements spread spectrum
modulation. For EMC (Electro-Magnetic Compatibility Test)
testing you may want to choose these options for optimal results,
we do not recommend you use these "S" frequencies, except for
special reasons. Some values you select may cause system
instability under some situations, please be careful. "N" means
this frequency does not use spread spectrum modulation, these
frequencies are for general settings use.

Multiplier Factor:
You can choose the following multiplier factors:
"
2.0
"
2.5
"
3.0
"
3.5
"
4.0
"
4.5
"
5.0
"
5.5
"
6.0
"
6.5
"
7.0
"
7.5

8.0 …………
However, differences will exist because of the various brands and
types available.
<Note 3> SEL100/66# Signal:
This default setting is “High” at 100MHz, and “Low” at 66MHz.
When you want to try a higher multiplier factor at 100MHz and
cannot chose it in “High” state, then you can set it to “Low” state.
Note: According to Pentium
®
II/III processor types, some Pentium
®
II/III
processors will have locked up the multiplier factor and disable this
signal. In this situation, there is no way to choose the higher multiplier
factor.
<Note 4> AGPCLK/CPUCLK:
Default setting is “ 2/3”. In this state, AGP bus speed will be CPU
bus speed divided by 3 and times 2. If you choose the setting to
“ 1/1 ”, AGP bus speed will equal to CPU bus speed.
<Note 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 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.
