Overview

This voltmod applies to the X700 PCI-Express using PCB #A379.

The blue Sapphire PCB has the same layout as the red ATI PCB, so it will work on all those models no matter which manufacturer.

Overview

Mods to solder

Pencil mods

hey , sorry but i dont get quite what this means, volt mods, what improvement does a voltmod have and.... what do you do? lol

Do you lower resistance on the soldered VR to increase voltage, or do you raise it?

Specifically where are the voltage read points, I can't make them out in the picture.

Thanks.

noboy better try this guide - you will fry your card! lol
Wizzard might wanna check the guide with an actual card before you post this - 20k on the mem will give you around 3V and 20K on the VGPU 1.9V rofl.

Nice pictures nevertheless

W1zzard · 09-01-2005, 01:49 PM

so which resistances do you suggest?

on xs they seem to suggest a 50k vr

@W1zzard:
Did you test the mods f. g. the pencil mods?
What resistance should it be afterwards?

I would like to do this Vmod but I don´t know how to determinate PCB number
coul you tell me where I can find it out please

tvdang7 · 09-11-2006, 03:03 AM

yea i have a hybrid sapphire x700 pro card. my pcb doesnt look like the pics so im guessing mine isnt compatible?

Nevvb1e · 10-17-2006, 12:28 AM

I have an Gigabyte X700 card
how can i know it used PCB #A379or not ?

jcdenton21 · 10-17-2006, 03:46 PM

hey guys
please help me
I woul like to raise frequencies on my sapphire x700 PCI-e (400/500)
it is stable at 475/630 but I think that 4ns samsung coul go higher
but layout is different
here are photos
