Question about changing my fsb

When I see people talking about raising there fsb on a A7N8X-X (which is what i have) they say they tried to raise it 200,201,202 ect...well on mine I can only raise it to 100,133,166, and 200. Is there something I didn't see that I have to change to let me raise it one at a time? Will updating my bios help?

 

are you sure those are not presets? is there a "manual" option ? increasing the FSB substantially can cause lockups n stuff like that

 

I think you must have overlooked it. I dont have that board so I don't know the exact location but just go through every tab and every option.

 

O.K.
I have ASUS A7N8X Deluxe 2.0 Bios ver 1007, your's is very similar, many of same features.
If you have to ask, probably should'nt, best to research first.
Anyway =
In Bios =
Advanced Chipset Features/ Cpu External Frequency

Dont you have MOBO Manual! info in there!
Bios? off hand dont know what each version offers several are avaible
