Socket-A Overclocking Guide

 

Onto Socket-A Processors

The first step in overclocking a Socket-A processor is to properly id

The first step in overclocking a Socket-A processor is to properly identify exactly what you have.  If you arenít sure what you have to start with, you wonít be able to know where to go with it.  Look at the top of your processor without a heatsink installed.  In the center is a raised area, which is the core.  Etched into the core are 3 lines of letters and numbers.  Read the top line and use the following diagram as a guide to identify your processor.  Things to specifically note are the default speed, and Max FSB.

The Multiplier Lock

Most AMD Athlon and Duron processors are shipped with a multiplier lock.  This means that any change that you make to the clock multiplier will have no effect.  There is however a way to unlock your processor, and make the clock multiplier functions available.  This requires you to perform an easy to do procedure to your processor.  On the chip, you will notice bridges, which are small contacts that are grouped in pairs, and then into groups of these pairs.  Some are connected together, and some are not connected.  You need to locate the group of L1 bridges. You can see a picture below

As you can see there are 4 pairs of bridges in the L1 group.  What you need to do is connect them.  There are a few ways to do this.  The first is to use pencil graphite.  A standard 0.5mm mechanical pencil works best.  Trace a line between each of the bridges to connect them.  If you use pencil, make sure to go over the traces many times.  Be sure not to connect any of the pairs to each other.  This picture shows locked bridges on the left, and properly unlocked bridges on the right.

Sometimes when using pencil, their will not be sufficient contact, or after time the contact will wear out.  I suggest using a more permanent means of connecting the bridges.  By using a conductive ink pen or a rear-window defogger repair kit, the connection between the bridges will provide perfect contact, and you do not have to worry about the contact wearing out.  You can purchase conductive ink pens from many electronics stores, be sure to get the micro tip version.  You can buy a defogger kit at any auto parts store.  It is a small bottle of liquid that can be applied with a toothpick or needle.  The bridges are VERY small, so take your time and be sure to connect them properly.  Once you are certain the bridges are connected, install your processor into the motherboard, and install your heatsink.
