I've been researching volt modding this card for the crazy overclocks people have been getting out of these G73 cores, however there are no guides for my specific model.
Looking at this guide at VR-Zone (http://www.vr-zone.com/index.php?i=3625), I can identify the ICs that regulate vgpu and vmem. However I am having a hard time finding voltage read points.
Firstly, my 7600GS has a stock clock of 500/400 rather than the standard 400/400. Since most cards can not clock that high on stock volts, I'm guessing this card has a higher voltage on the core than normal, therefore finding a read point is harder since I dont know what voltage to look for.
The guide at VR-Zone says to look at the inducers near the voltage regulating ICs. Here are the voltage readings of the three inducers that are on this board:

And here is a picture of the front of the card to get an idea of where the components are layed out:

Stock voltages should be 1.1v and 1.8v for gpu and memory respectively, however mine seem to be ~1.3v and either 1.88v or 1.6v respectively.
I can only get a 25Mhz overclock out of my memory, compared to the 60-80Mhz most people get. Could this mean my memory is undervolted to 1.6v? or does it just not clock well :shrug:
Any thoughts on this, which voltages are which, for read points would be appreciated.
