) your houpe is right....it is digital multimeter.
Anyway....if there is any measurement i can do...tell me.

dolf said:Klootzakje, if my suspicions about R420 (R423) get a prove, soon I will need your support. But until I have't positive result from my "measuring request" to Fresko I prefer to keep silence .
See you soon

if you want i can mail you the coredolf said:Sean It is nice. In that state the core can help a lot. The electrical relations on the core are much more important for me than on the PCB. Of course even cracked the PCB could bring some info especially for the external core - PCB connections. I hope that you have the pieces .
I am very curious to know about the possible connection between the following parts:
1. Do the dots have a general connection in between at least on the one side?
2. Whether this general connection (if exists) is connected to the front side?
3. Near to the (5 bridges) part has square pad and my question is how / whether this pad is connected to one similar on the front side?
4. What are the relations between GND and the bridges (cutted bridges)? (GND you can find on the front side of the core - my picture in the previous post for Fresko).
This core was with functional 16 pipes and have 2 lasercuts on the back obviously it have to be like that on 16 pipe core. Probably on 12 or 8 pipe cards the configuration is different (I will try to understand what) but for me is important to understand the mechanism of cutting (fusing). Not how the process works but what the effect over the core is.
This core is gold in that position (for research of course).
But your discovery is what I am afraid of because if there is no connection point left after laser cut we can do nothing about re-connection (missing second connection point). Also the situation becomes worst because there isn't access to the back side of the core.
At present I will remain optimist until no prove that there is no way to fix the core cuts.
The situation have to be similar on R480 (lasercuts hides on the back side).
One thing is clear now: This operation takes to core producer just few seconds to done "his bloody job" after testing but for us (if possible) it will take much much more time to fix it.
klootzakje said:does any1 know if someone ever succesfully unsoldered and resoldered his gpu core? cause if it turns out the mod can only be done under the core.... guess i'll have to try then...
i have an old 9800 pro which is almost dead.. i would first test the un- and re soldering the core on that and see if the card still works :O
anyone ideas? tips? urls to threads about unsoldering core? :O

F!reF0X said:Maybe we could use a hairdryer (Haarföhn) to de-soldering the gpu? I saw somebody doing it with ram (old ram ofcourse). He put the hairdryer above the ram and wait until the soldering get liquid and removed it an put it on a other ram module.
Maybe this is the safest way to get the gpu from the PCB?. Maybe it is possible to put back the gpu on the same way

doh lol make a pretty picture of what you want me to measure and ill do it for you k (i dont get exactly what you want in that other post )dolf said:Sean, the idea to mail me the core is great and for sure the BEST we can do. But I have to inform you that I am situated in Europe. If you haven't problems with sending to here and it is not expensive for you I will provide my address.
Otherwise we have to think obout other possibilities.
Thanks for the constructive proposal and for the support .
