Asus A7V FSB question

[Corinthian]

I have an Asus A7V with a duron 800 processor that I'd like to OC. I locked the L1 bridges and was starting to set the switches when I realized that my MoBo manual is not correct on the layout of my MoBo. There are supposedly 4 FSB switches according to both a picture in the manual and on how the FSB settings are explained in the manual. On my motherboard though I have DSW switches 1-5 and not 1-4.

I tried setting only the 1st 4 switches and the switches for my multiplyer, but then I couldn't even get a picture on the screen. I don't wanna fool around to much with this when I don't know what that 5th switch is for and how it should be set for a FSB of 100MHz.

Could anyone please tell my why that 5th switch is there and what it does?

on my old a7v, i had 2 sets of dips
1-4 for the fsb and
1-5 for the multiplier

So i'm thinking that the board you have doesn't have fsb dips and you are messing with the multiplier dips.
If this is the case, the fsb can probably be adjusted in the bios, hopefully. But with the a7v, the best way to oc is with the multiplier anyway, as the chipset isn't stable much higher than 110.
Check what revision you have of the board too, i had rev 1.02 (it's printed between some of the cpi slots i believe)

No, I now it is the FSB I am looking at when I am trying to OC. The board is rev 1.04 and the FSB has 5 switches and the multiplier right next to is has 6.

the multiplier is not a problem here as the manual shows the settings for the miltiplier switches, but the FSB only show settings for 4 switches while I got 5

(the picture of the A7V in the manual only show 4 FSB switches where I got 5 )

Get the 1.04 version of the manual from :
ftp://ftp.asus.com/pub/ASUS/mb/socka/kt133/a7v/a7v-104.pdf
It has separate settings for 1.04 and 1.02
