It's going to be a little more involved than that.  The Celeron 300a is
clock-locked at 4.5.  So your only option is 450.   On top of that some
motherboards will give you an error if you try to run the FSB faster than
you are supposed to.  You might want to look at Tom's hardware guide for
some information.  http://www.tomshardware.com/Celeronto100.html

Subject: [PCBUILD] Overclocking Iwill board


>Hello Listmembers,
>I have an Iwill BD100 Mobo with a Celeron 300A, the board jumpers have
>markings which indicate speed in mhz, instead of FSB speed and multiplier
>settings. it has 233,266,300 and 333(with bus at 66 mhz persumably) and
>350,400,450,500(with bus at 100 mhz persumably). Am I correct in thinking
>if I set the jumpers at "400", it will be the same as setting the bus at
>100 mhz with a 4x multiplier. it's my first overclocking try and wish to be
>sure about settings. Any help would be appreciated. TIA
