have found some 50uH or 19uH 25A, is ok or i need abosolutly .68uH ? ( sorry but I don't understand wat uH value, means )

Sorry for my bad english, I'm from italy
George this mod based on the vmax terminal?

hey i have a small problem, well i did the your mods to some 8800 GTX and the smd for vgpu fell off. there aren't solderpoints anymore so i cant solder the smd back on board. how do i manage to bridge that ing smd :/
I love Extreme Overclocking
Yes Johnny.....BUT there MUST be a little Vdroop on the VGPU so NOT to produse to high VSpikes so to work properly....
Hmmm.......Now you're screwed....
....now you HAVE to find the "line" that goes onto the VCore leg of the chip and solder on it - NOT YOU, ask for someone else to do this for you j/k - ......
INTEL PWA FOR EVER
Dr. Who my arss...

gutting wondered if we were all in the same boat
Well it seems i have nothing better to go on (no other people trying it) so ill just have to try my luck and redo the mod, but without being able to measure the resistance.
Hipro, approximately how many turns down in resistance on your 25 turner did you have to make to get the ~5.1K reading?
So does this mod help anybody?
Reading the posts it does not really seem so...
Is there anyway to get a linear supply at say 1.6//1.7//1.8 volts and power the core with that? That is really what is needed to get nice clean dc to the core and then I am sure the MHz would sore, and so would the stability....

well I don't no too much about completing the mod, but I am an electrical technologist and we use linear power supplies...such as a techtrol, to supply analog equipment to ensure accurate reference voltages. The voltage does not fluctuate under load and it stays very "clean". With a scope meter the wavforms will stay nice and flat with varying loads. And that is exactly what is needed for the gpu to operate consistently and stable.
And looking at a video card the circuitry is not capable of providing what is needed.
Any thoughts from anybody?

I dont follow what your post meant. 1.6v, 100A, is that supposed to be the ratings of such a power supply?
Where does 100A come from, I must totally misunderstand what your post mean because if 100A went through any part of the card it would break?
Anyway even if you found say a 3V supply, or a 5V supply you could set yourself up a series circuit with some big resistors to drop the voltage down. Use a big heatsink and a couple fans to deal with the heat.
Is this a legitimate solution? What kind of current would an 8800GTX's core draw at say about 1.7V and 760...800MHz core speed?

ok i totally disagree with you and you need to give more of an explanation as to where you come up with these current figures.
Have you ever seen a cable that is designed to carry 100A? Its not a tiny little kiddie cable, like the components on a video card, there is no way a video card has that kind of current travelling through it. Do you realize how hot it would get?
Maybe I am totally wrong but everything I have seen out in industry tells me that there is no way there is anywhere near 100A going through a video card.

i dont understand this at all
can someone convince me, there is nothing on the card that can carry 100A, so this makes no sense to me. The core is drawing that current from somewhere on the card so the current is traveling through the card to get there
