GeForce GT 710 Voltage Modification Beginner’s Guide

The GeForce GT 710 voltage modification beginner’s guide by Ben “Newlife” O’Neill helps you get started with advanced overclocking. With his permission, we publish the guide at Overclocking.guide. We encourage you to have a look at the original thread at the OCAU forums.

 

Introduction

This guide is intended for overclockers who would like to try their hand at hard modding a card plus to help people in the OC-Esports (HWBOT) CHEAPAZ CHIPS competition

Disclaimer: Following this guide has a high risk of failure and no one but yourself is to blame if you kill something

The idea is simple as it involves soldering a trimpot to a FB (feedback) pin on a PWM controller, but requires some soldering experience. A cheap card like the GeForce GT 710 is a good place to learn. If you have no soldering experience, try on a dead card first

You will need the following equipment:

  • A multi-meter for reading voltages
  • A soldering iron and solder (lead is best) for soldering
  • 1x 20k Ohm multi-turn trimpot for GPU core
  • 1x 50k Ohm multi-turn trimpot for memory
  • Thin wire for the modifications
  • Hot glue for holding wires and trimpot in place
  • Something like a third hand tool for holding things while you solder (optional)
  • Heat shrink tubing to prevent shorts (optional)

We used the following graphics card for testing:

Let’s start with the GPU core as it’s the simplest to do.

First of all, find out where the FB pin for the core voltage is before beginning. Once that is done you can get started by tinning the IC leg shown and some wire. Afterwards, just bring them together and apply soldering iron.

Next, it is advised to hot glue the 20 kOhm trimmer to somewhere on the card and cut back of one of the outside legs. Important: Make sure the trimmer is set to maximum resistance for the pins you are using. Solder the wire to one (pre-tin both wire and trimmer leg) and solder a another wire to one to any ground.

Below you can find the voltage modifications for various GeForce GT 710 graphics cards.

 

GIGABYTE GeForce GT 710 1/2GB

GPU Core Voltage Modification Point

GIGABYTE GeForce GT 710 1GB Vmod

GPU Core Voltage Read Point
GIGABYTE GeForce GT 710 1GB Vmod

GPU Core Voltage Modification Completed (orange wire)
GIGABYTE GeForce GT 710 1GB Vmod

Memory Voltage Modification and Read Point

GIGABYTE GeForce GT 710 1GB Vmod

Memory Voltage Modification Completed

GIGABYTE GeForce GT 710 1GB Vmod

 

MSI GeForce GT 710 1GB

The GPU and memory use the same IC and is the same as the GIGABYTE card, but use a 20kOhm or 50kOhm trimmer. It shouldn’t matter too much which you use, however a 20k will set volts slightly aggressive.

MSI GeForce GT 710 1GB

GPU Core and Memory Voltage Modification Point

MSI GeForce GT 710 1GB Vmod

GPU Core and Memory Voltage Read Point

MSI GeForce GT 710 1GB Vmod

For anybody who wants to know: I found which IC was used by looking up datasheets and testing the resistance between the voltage read point and its respective IC (pin 8 for this one). It read 1 Ohm.
