I tryed the pencil to make my cpu(axda2600kv3d) mobile and to get the vcore to default(some bridges are cutted) and I have nothing.I understood what should I do but I don't know what to use for it. With what should I fill the gaps(the material not in a comercial form that I can't find here, also my cpu seems to have the bridges coverd with plastic and I can't use wires).I wouldn't want to cut bridges.

I have always used 'Rear Window defogger repair solution'. It is a paint on stuff, much like nail polish, that you get at an automotive repair store. At least, here in the states we have alot of stuff like that. It paints on easily, and dries in under a minute. If you ever mess up, you can wipe it off using Acetone.
If you cant find that solution, you might have to get a conductive pen from an electronics store.

I buy conductive silver paint from CONRAD.They must have shop in Bucharest too.Works fine and you don't even need to fill the gaps.Here in Bulgaria it costs 7EURO for a small 3g bottle.

As for being covered with plastic, the ends of the cut bridges that you need to connect are under a layer of the PCB on the newer CPU's. Get a 10x or 15x jewelers loupe or some other kind of magnifier that leaves both hands free. Mask off the bridge with scotch tape, put a drop of super glue in the trench. There are some bridges that you don't have to fill the trench with glue, like the L5 mobile, but I fill them anyway just to be safe. It only takes a couple of minutes to do. Remove the tape, let the glue dry, then use an exacto knife or razor blade to trim the super glue flat with the PCB. Wrap a piece of 600 or finer grit sandpaper around a toothpick and sand the bridge carefully until you just see a glint of copper on each side of the trench. Connect glints of copper you uncovered with a conductive pen or mask the bridge with tape again and paint the bridge with conductive paint. Let it dry a few seconds and remove the tape. Tedious to do, but after some practice, it takes only about 20 minutes.
A website somewhere like Toms Hardware, Anandtech, etc. has a good video showing how to paint bridges, but I'm at a loss finding it. Anyone know where it's at?

@oldandfast Believe me there is no need to fill the gaps.There is no need to remove the plastic also. A simle drop of paint in the gap and it's done. To remove the paint use some thiner or acetone. This way you can keep the warranty.

Thanks to all, I never expected this feedback. I would like to use your method momchil, but I wan't to know if it is realy safe on the vcore. Also your method, oldandfast, seems to be very safe, but if it voids the warranty( not even a month since got this in replace from RMA).Just in case the vcore needs it.If I understand this the trench that I need to fill with superglue is what I know as gap.The superglue is an insulator so that I don't ground my bridge and the tape is for the mess that I could do with the superglue, right?

Yeah, the tape is just to confine the mess and the conductive paint, because you're working on a very, very small area. The reason to fill the gap is because some of the brown substrate CPU's, such as my own XP2500+ Barton, have a grounding plane at the bottom of the trench. Certain bridges can't be closed by just filling the trench with conductive paint as they will be grounded to this plane and cause problems. Read this topic LINK for more info. From what I've read there, the green substrate is safe to close the bridges as momchil suggests (and save your warranty). I just fill them all to be on the safe side and not kill the CPU.
Hopefully, Honey X will join us here. He's a lot more knowlegable about this, has done this many times, and should be able to tell you exactly which CPU's/bridges can be safely closed without sanding or filling.

Hey, i just checked the Fab51 site, they say it is safe just to directly paint the L11 (VID) bridges. They go to ground anyways. So you can skip the superglue step.

Cheap and easy is what I did: Grade B pencil small piece of transparent sticky tape. Fill in bridge and join then use sticky tape to seal link. BTW has anybody joined both bridges in the L5 group to enable all 24x multis ?

thanks to all this should be sticky. the conductive paint seems to be the way.My cpu is almoast coverd in plastic except a few fake dots and the gaps(wich I can see with my eyes) so I think the grounding should not be a problem so this.that link cleard things up oldandfast. with the pencil(guess you are talking about HB) it did not work.

momchil why do say it aint gonna work, Iam running my sempron using the pencil method NOW ! note you have to use a good quality grade 'B' pencil the graphite has to be thick and dark.
Anyhow can you tell anything about Asrock K7VT4+ you seem to build a few asrocks ?
ciao.. RB

Hey RB give us a description of what you did and what the end result was. If you have a working Pencel mod on a New Sempron we all want to know about it.
pics would be a bonus too.
Please list your system specs.
Thankyou!!

for me the pencil trick dosen't work. Used a rotering mechanical 0.5 and HB2 only to fill the gaps.had no influence
