Anyone blown AMD bridges?

[dajo]

Did you guys see this article at overclockers.com about frying your L3 and L4 bridges with a current supplied by your PSU?

Has anyone tried it?

I've got a few Durons lying around so I'll probably give it a shot soon. What I don't understand is that the before picture shows the bridge in tact, and after shows a gap just like on the L1 bridges for a locked CPU. Does the electrical current actually blow away that material, or melt it?

Take a old psu cord and then make a U witha real thin piece of copper wire. Take the U and place it in the end of the PSU cord with one end in one power slot and the other in the other end. Now plug it in but before you do make sure you are standing clear of the debris and possible explosion Yeah it will melt the wire or electromigrate the bridge so it isn't there anymore.

I blow them quite frequently.

So, basically, can I open my box, boot up, and attach the wires to an unused PS power lead to blow the bridges on my guinea pig cpu while my machine is running? Am I going to fry anything in my running system if I do it this way?

Ummmmm, dude what are you talking about?????????

You really that crazy?

No, you should pull the cpu out completely from the socket and then do it!

Wow!

Uhhh, gotta say that again, WOWWWWWWWWWW!

I wasn't talking about blowing the bridges on the CPU running in the system. I was talking about accessing the power lead on a PS that was up and using that to blow the bridges on another CPU that I would be working on nearby.

I'm not that stupid! (although at times I come close...)

I don't quite understand the technique you are describing in your post. Are you talking about tapping into a PSU power lead from a PS that is running, or are you talking about just using a PS cord and the electricity from a wall socket (kind of sounds like that's what you are saying).

Would not you blow the fuses in your house?

IF you got a AT PSU then it should work as the switch is on the outside of the PSU and not going through your mobo. A 9 volt battery may do the trick too. Maybe? I wouldn't do anything with your system powered on like this. I always cringe when my modified 7v fans wires slip out of the four pin connectors and shut my whole system down. You would likely find the same thing happening to yours and may damage something bad. You don't have any AT psu's around there any place? If so use them or try the 9v. Not sure if it will have enough power to pop the brdges but it won't hurt trying. The first post I gave was kind of a joke. I have taken 120v and did crazy stuff before like I said take a thin piece of copper wire and basically route it into the outlet I was joking and didn't think you would take me seriously about that. I though the stand back for the explosion would have triggered that
