pin mod for high multipliers

Hi,
i was looking at the pin-mod guide on www.ocinside.de and i'd like to try
it to start using higher multipliers (>13) on my barton 2500+.
It seems the simpliest way is putting wires in the socket, but i don't
understand how to simply switch to higher multipliers... the interactive
guide on the website has selection for all multipliers and for "Unlock -
Multi via BIOS up to 12,5x".
Do you know how to get multipliers via bios starting from 13x using this
method? It would be the same as cutting 3rd and 5th L3 bridges.

I wanna switch to higher multipliers 'cause i have a 4bit multiplier
motherboard with slow fsb.

Thank you!

Basically if you look at that and change through the multipliers you will
see what you need to do to get 13 or above, or 12.5 and below.

Start with the first multiplier option "Unlock..." to see which connection
we're talking about, then scroll through the selections (ignoring
multipliers 3 and 4)... when you move from 12.5 to 13 you will see that
connection change to what you require.

Should just need this one to change the default multiplier.

I think that fixes to you <=12.5 which is where he currently is. If you
pivot that connection 90° anticlockwise about the top pin, I think thats
what he wants.

Having just done this on two chips, I can conclusively say that you need to
join *2* pins. Which ones?

Set the interactive pinmod thing to 11x and print out (or remember) the
configuration. Now, change it to 15x. Note the two links that change. These
are the ones that you need to do. This locks you in to using the
multipliers:
15x (set board to 7x)
16x (set board to 8x)
16.5x (set board to 8.5x)
17x (set board to 9x)
18x (set board to 9.5x)
22x (set board to 7.5x)
23x (set board to 10x)
24x (set board to 10.5x)
This should give you a good range to work across if your board/memory fails
at much abobe 145MHz. Alternatively, do the same but link the two pins that
change when you set it to 13x. This will give you access to the multipliers:
13x (set board to 5x)
13.5x (set board to 5.5x)
14x (set board to 6x)
17x (set board to 9x)
18x (set board to 9.5x)
21x (set board to 6.5x)
23x (set board to 10x)
24x (set board to 10.5x)
This one is probably better if your board/memory can hande 160's and 170's.

Why do you need to set two pins? Well, you obviously need to tie one to
vcore to set the 5th multiplier bit to high. Then, you have the multiplier
10000, which is invalid. Since the bios does not set a custom multiplier
until POST, the chip needs to have a valid multiplier at default. So you
need to tie a second pin to vcore for the chip to even start.

Note that you probably should NOT try to set a multiplier that conflicts
with the pinmod you made, as this could possibly damage your motherboard or
CPU (though the chances are unlikely). In any case, it won't set it as
pinmods override the motherboard.

Hmm, I was under the impression it toggled the 8x bit either high or
low opposite of whatever the default was? Although it isn't very
often you'd want to so...

I tried that and i got a strange behaviour... i'm always with lower
multipliers, but now changing bios settings gives me this frequencies...
5 -> sometimes 12.5, other times does not post
9.5 -> 7.5
7.5 -> 7.5
7 -> 7
My barton is a AQZEA 0333 TPAW.
I tried to switch to higher multipliers even by cutting 3rd and 5th L3
bridges... they're cut and i proved that with a tester, but i'm always
with lower multipliers... it means 1250mhz on my abit kt7 raid :-(

Do you have other ideas? Thank you all!

I presume you removed the pinmod before changing the bridges ...

That's really, really wierd, especially the "sometimes" booting on 5x. The
only thing that I can think of that could cause this is modding the wrong
pins or cutting the wrong bridges. Or possibly a dodgy pinmod on the 5th L3
bridge pin (checking the resistance between the pins should verify this).
The pins I modded looked like (fixed-width font):

O O O O O O O O O

O O O O O O O O O

O O O O

O O O O

O O O
\
O O O O
/
O O O O

O O O O

Using the same view as the interactive pinmod guide.

I have no idea why yours doesn't work. It's been proven to work in other
KT7 boards. There's just 2 possibilties that I can think of, either the 8x
multiplier doesn't work on that cpu or you screwed up the mod.

This setting is one of the many i tried without success... a few minutes ago
i even tried this way...

http://www.beachlink.com/candjac/Workarounds.htm#Pic2

that using the pin view would look...

If i understood it right it seems the mods are the same, 'cause the pins i
marked as * are in common and are simply grounded differently.
Is that correct?
By the way, with L3 3rd and 5th bridges open (just like this
http://fab51.fc2web.com/pc/barton/img/L1L3_13x.gif), what could i try now?


Thanks
