Can some one verify if that suites?

So This one I suggested earlier is valid? Haven't got an opportunity to made it.

Errr?
You have already posted a guide for the mod haven't you? It looks perfectly valid if that's what you wanted to know.

Yes, that's it. I don't have a card to test it right now... so I'm not sure if it is working fine, and I'm not sure about the measure points and wich one is a good ground point to solder.

[demonkevy666]

flow the 4850 one with your in the right place one the 4670.

[largon]

I can say those measuring points are valid.
And you don't even have to solder the ground, just clamp the wire onto the grounded ring around any of the screw holes.

I've got a question about this mod.I believe that the right modd helps Vcore.The left is for Vmem?If not ,can a single mod (either the left or the right)can work without the other.


Thanx in advance

I have the 1GB card and the vgpu area is slightly different. which solder pad is ground in this mod and which is the mod point? My card only has one of the two showing, im hoping its the mod point.

This is what my 1Gb card looks like.









I also moved some caps etc to the back of the card, so I could mount my pot.

Update now the 2. place in 3Dmark 2003 is taken...

Here is some pics of the setup in the Shuttle barebone.













Here is pics of the vmod it self.

:o
Are those VRs glued on the cards or do they actually just hang in there by the legs?
That last pic would imply there is no glue... I personally wouldn't dare tuning them VRs if they were not fastened somehow.

[Riska]

They are just hanging there it was done quickly
