need a volt mod for Galaxy 7300gt 128mb DDR3

[zoran555]

Hi!
Just got this card for my girlfirend planning on some co-op NWN2 and need to make her experience a tad better.
I've been searching around and found some info, but it seems I got a newer PCB, so I came here for some pro advice :DD:

From stock 500/700 (4317 3dm 05), I can get to 560/820 (4859 3dm 05).
Mem is kinda nice, but gpu won't go more than 565 without locking out :(
I just know that this card can do better.

So here are the pics:

If you need more detailed pics just ask.
Thanks in advance!

You are saying that I do as refered to in this thread (http://www.xtremesystems.org/forums/showthread.php?t=101059)

But my is different in from the one pictured there? Even the IC is different?

That r451 resistor?I tried to pencil mod it, but do I measure my pencil modding? Can I just measure its resistance? Or do I have to power up the card and measure the volts?

I managed to get the resistance from 700 to 692 I think, how does that translate to voltage for the gpu?

on the GPU i believe its every 20 you go down on resistance it ups the voltage .1v and memory is really touchy so i wouldnt go down to much

Well, I went ahead and dropped r451 700->686 translates to 1.42v for the GPU.
That got me to about 630MHz for the GPU. :/

What bothers me is that 631/800 got me 4940 05 marks, compared to stock 500/700->4150?
This is tested on a sempron64@2.485? Is the cpu holding it back? I don't have time right now to test the card with a a64@2.6GHz, but I don't see how is it possible to come close to 7k 05 mark without some crazy cpu OC :(

thats a really good increase for a voltmod......looks like cpu is holding you back my 3dm05 is 7104

:cry:
Just tested it with my venice 3200+@2.6.
630/792 => 5163 3dm05
:banghead:

This isn't working as advertised :(

Have to figure why later, it's kinda late here...

If you would be so kind to test at 630/792, so I can compare, I'd be grateful.
