Athlon XP 2500+ bridges

[The Black Pumpkin]

I have gotten three Athlon XP 2500's, and I've noticed that there is not a single one of the L bridges cut anywhere!

Now, if anyone is familiar with Socket A processors, you'll know that the L bridges control FSB, multipliers, and voltages. I know that these three cannot be normal, because I borrowed a 2500+ from a friend and it does have bridges cut.

Is it possible that these got shipped out uncut from the Fab? Shouldn't cutting the proper bridges (whatever they are, still have to look that up) make the cpus work? (They currently do not in their present state.)

This is very wierd.

seems Barton has the normal bridges, well at least some of them.

neat find though!

Yeah it is, isn't it?

Mine's even better than that one, though. Click on the big picture, and you will see that there are at least one or two of L4, L12, L5, and L11 cut.

Mine has NONE.

Totally awesome and strange...

So nobody has any other clues on this?

If I remember it well, mobile Athlonxp didn´t have any bridges cut, that it´s the way you can change the multipliers an have the save energy feature. Anyway I´m not sure at all, but maybe you have a mobile 2500+

Well, unless someone changed the labels on them, they are definitely desktops, because according to this processor listing, it's right in line with the desktop Barton 2500.

I'm looking for a diagram or information or something that'll tell me what each bridge does, and then I can try to make the thingies work. It'd be sweet if I could, they are supposed to be easily overclocked to Barton 3200 speeds!
