vielleicht hat ja irgendwer noch nen tb rumfahren und kann mal nachmessen, ob der punkt rechts dasselbe potential hat wie die "weggebohrten"...?

even if those points you drilled away and the one on the right were electrically identical (which i don't know and the above german question is about), there would be a problem:

what if the connection burns where i put the yellow flash? then you couldn't continue burning the other bridges!

I understant what you're thinking.

But if the electrical schematic was like this, could it work ?


(The little black rectangles represents the micro-fuses)

True OR false ?

So... does anyone know the easyiest solution to do this ? I'm sure someone knows what is this contact on the right of the picture.

Thanks for helping me !

(I don't want to continue drilling my processor because I think i'll destroy it, i don't have the good tools to do it)

I wonder why you would want to modify the L7 bridges...

Anyway, IF the schematic is right, you would just destroy the contact between the dot on the right and the last bridge, so it would be useless

I want to cut those bridges to undervolt my processor.
On my motherboard (gigabyte ga7ZX-H (kt133a)), and with any bios it's impossible ! I tried with cpumsr too... but it's not possible !

The only way is to cut those bridges on the processor.

This schematic is not correct. It's only only a supposition.

I only want to know if it's possible to do it with this contact on the right of L7 bridges and I hope someone can help me

Please help ! :thumb:

It's impossible. The line will be cut anywhere. It could also be cut in the horizontally part of line. You cannot control the the point where it burns.

And your paintin is wrong. The points on at the bottom aren't connecten with each other.

if the schematics are correct and if the fuses are significantly smaller in cross-section area than the other line, it could work.

by the way this is not the only way to undervolt for you.
check out the pinmod section of workshop and think about isolating or breaking single cpu-pins...or using them as second contact for burning...

but think, before you break!!!
each voltag-pinmod uses 2 pins, and you must only break one of them- the one connected to the bridge (get a pinout schematics of thunderbird!!)

also you could cut and alter the vid lines somewhere on your board on the way to the voltage regulator...
get a datasheet of the voltage regulator and see, which pins vid(0..4) are and alter them there.

good luck ;)

How do you know it ? Can you give me a link (url) to a schematic for the thunderbird ?

I wanted to do this, but there isn't any pinmod guide for the thunderbird...
Am I wrong ?

The only one I could find is here, and NOT for thunderbird.

google-search, first link dude....

page 58 and following.

i would guess that voltage pins for thunderbird and thoroughbred/barton are the same, because the mainboard/socket is compatible...

please do some research yourself now, i'm not going to look into that datasheet...

Best thanks to everyone !

I sorry ! I haven't tried a google search with "datasheet", but with "pinout schematic" and that's why i didn't find anything.

My english is poor...

Now i'll try to understand these schematics..

If anyone has some good advices, i'll listen to them !

Thanks !

just check your default core voltage with a system monitoring tool (or maybe you already know), enter it in the pinmod guide and compare the resulting picture to the pinout in the datasheet.

you will then know, which vid-pins to rip out in order to get to zero voltage (also you can rip out all five of them).

then you can apply the pinmod with little wire-bridges to set your desired voltage.
