7900GT OC - Can I get anymore?!

[Phunky Phish]

I have these Asus 7900GT's running at 118MHz PCI-E bus and clocked to 548MHz core and 783MHz ram.

Anyone know if I can push these any harder?
The core temps show 39c at idle, will check after some bench marking!

Let me know

There are volt mods for the core and memory, allowed me to clock to 640/1900. For the core volt mod you need conductive ink/paint, but for the memory volt mod all you need is a pencil.

Btw does overclocking the PCI-E actually give better performance?

I don't know, but I plan to run some bench marks so will post some results!

Any idea where I get volt mod info? Would love to up the mem n GPU to that kind of speed!!

Those are the default settings by Coolbits. Need to try upping them a little manually!!

Here's a link showing where the memory mod should be done. On the first picture where it says "VMem...pencil". What you need to do is shade in that entire resistor with a pencil. This will allow the voltage to increase, meaning higher clocks. It worked for me, but try just shading in lightly at first and testing it just to be safe.
