I can't change the FSB on my P3B-F Help !

[Bert770]

I have a Asus P3B-F mobo and I want to run the memory to 133 Mhz. But, when I go in "Advanced settings" of my mobo BIOS, I can't change the core or something like that. This one is in grey. I don't see any option where FSB is written in my BIOS. Do I have to change some jumpers on my mobo ? Please help me ! Thanks to anybody who will give me a answer.

i believe there are jumpers or dip switches but not sure

Make sure all 10 dipswitches are set to the OFF position.

Make sure that the JEN jumper is on the correct setting (please see your P3B-F manual for the location and setting).

In the Advanced Menu of the BIOS screen, set CPU Speed to Manual. Set CPU Bus/PCI Freq to 133/33.
