Duron Bridge Breaking

[Guest]

Anyone know of an effective way to cleanly break the bridges on a Duron CPU.
I dont have any special tools to do this so any help would be very appreciated
Anyone done it with a sharp knife?
Thanks

with what did you link the bridges?
a crayon ?

... BTW: why break them?..

Read the post on this site about the pencil trick to close the bridges that will help you
The reason I want to open some of the bridges is to change the multiplier on the CPU because my motherboard doesn't have jumpers for this so it has to be done on the CPU as described in an article on this site

i would say just to look in to a new mobo becuase it is very easy to mess a chip when breaking the bridges nad it while proably be alot easier to get a new board

(Copied this from my other reply to your same question)

Well the best way is to have AMD do it at thier fab before you get it.

If you're going to do it this way you have to be willing to take the risk that you CPU won't work after. Take it to a jewelry store that does in house cutting/etching. Most places outsource so it may take some searching. I found the problem what was done to my processor was that the circular saw the guy used to cut the bridges had a wider blade than optimal. As a result the some of the studs got ground down to the surface of the ceramic. This was especially prevelent at first when the guy was getting the hang of it. If you recall Tom posted the multiplyer settings so that's where you get them. Check with them first so you can figure out if your L7s (voltage) need cutting. eg. to get 1.75 or 1.85 from 1.70 you just fill in 1 or 2 bridges.

Even with the "tape trick" I still think pencils suck, it's $10 for a conductive pen and then you can forget about it.
