What is the easiest and cheapest method to close/open bridges on my duron 700?

[geezus]

Before i go and tear up my processor, i need to know how to successfully close bridges without destroying anything. I have already decided to use a pencil (because it seems to work for everyone) to open them. Never done it before so i am trying to be as careful as possible. One last thing though, if i use pencil lead to connect these bridges isn't there a large chance that it might flake or fall off and disconnect the bridges while i was using it?

The graphite shouldn't fall off unless you touch it. If it does, then your CPU is just locked again and all you gotta do is redraw :) . If u need to see how to draw them in check my pic over on the left. If when u first try it the multiplier doesn't get unlocked, take the CPU out and press a little harder with the pencil. ALSO I recommend using a 0.5 MM mechanical pencil. Hope this helps!

thanks for the advice, but i still need to find a a safe way to close bridges without damaging anything. I have to be able to reconnect them. would exacto knives work?

I've asked the same question in here and noone seems to have an answer, I can offer up my experience.
I have tried a dremel with a micro bit and a razor knife but still I cant seperate them, it seems they go deeper than I imagined. I've inspected them under a strong magnifying glass and they still seem to be connected. This must be the case cuz when i put it back in the system it fired up as normal. I'm using a 1gig AXIA 0111 with a Gigabyte GA-7DX, its a nice board but has no multiplier settings. Eventually I will try again, I will post my results if it works :).

Oh I didn't know what you meant cause you have the wording backwords. Drawing in seperated bridges is called closing them, not opening them. And to cut connected bridges would be opening them. At least that is how I would word it. Sorry though, I don't have any advice on how to cut them open, although I have heard from someone else (besides the guy who posted above) that they used a dremel to open them and they said that worked.

Very confusing wording...care to clarify?

Since my last post I've tried again and finally some results, what I did was use a Dremel tool with a thin grinding disk, I wasnt sure how deep the bridges went but i just kept on grinding (all in the name of progress!) and finally they disconnected. Just take your time and clean the disk on another piece a metal or something cuz the ceramic likes to round it and take away some cutting ability. BTW I'm glad to report my 1gig AXIA 0111 is stable as hell @1400, air cooled@49c. Still waiting for Swifttech to send my waterjacket before I attempt anymore. Good luck Geezus, hope this helps

I'm glad it finally worked for you, as of my last post i had added the scissors technique to my list of unsuccessful attempts at cutting those bridges. Tonight i am going to try a very sharp exacto knife and hope for the best. How deep should i cut it? BTW, did you change the multiplier through the chip itself? Noone else seems to care about this idea...I appreciate all the help.

The bridges run deep enuf that I dont think a sharp knife will work, I tried that one as well. Using a dremel with a thin disk is best. Yes, that is how I set the multiplier, I had no choice cuz my board has no support for it. good luck

the easiest way would be to get a new motherboard. ;)

I used an engraver to open my bridges. It is brutal though and I would not recommend it if you want to reclose them. I gave the dremel disk a try, but even the thinnest (pinkish brown) ones seemed too thick.
