XFX 8600 GT Vmods - New board layout?

XFX 8600GT 540M 256MB DDR3.
Just picked up two of these for a bargain price. They clock reasonably well but i need help with the volt mods if i`m to make any kind of challenge in the rankings. I googled for mods but no guide matches the layout of my card. Has anyone got any idea where to mod and where the voltage read points are? Pencil or hard mods, any help would be great thanks. Here are pics of the card.

I`ve done some digging around and downloaded the data sheets for these controllers and i think i might have worked it out. Can anybody confirm this please.

Really need to know what voltage read points are so i have a starting point.

Yes, RT9259 is for Vgpu and that other is for Vmem, but what markings it has?
On RT9259 - if that resistor connects FB and GND then yes, You can pencil it. Same goes on Vmem IC.

These measuring points should work: http://ceemic.pri.ee/hardware/xfx_8600gt.jpg
