The 845E-ANT MAINBOARD
Page 45
If you look at the top of Pin 2 in Pic 2b you will see that there is no connec-
tion to the AGP card. This means that this is a 3.3 volt AGP card and can
therefore not be used on an Intel
®
845 mainboard.
In Pic 1b a narrow line can be seen protruding from Pin 2. This line, which
ends in a circle, is the connection from Pin 2 to the AGP card. If Pin 2 on your
AGP card has this “thread” then it is a 1.5 volt AGP card.
If there is no connection from Pin 2 on the Solder Side (Side A) of the card
then it is a 3.3 volt AGP card and cannot be used on an Intel
®
845 mainboard.

Introduction
This mainboard uses the Intel® 845 chipset and therefore only a 1.5 volt AGP
card can be used. There are two methods of determining whether the AGP
card you are using is a 1.5 volt or a 3.3 volt card. The first method is a
physical check of the card and the second is a simple measurement.
Method 1: Physical Check of the AGP Card
The first method of determining whether you have a 1.5 volt AGP card or a
3.3 volt AGP card is to see if Pin 2, on the Solder Side (or Side A), is con-
nected to the card itself. If there is a connection from Pin 2 to the AGP card
then it is a 1.5 volt AGP card and can be used on an Intel
®
845 mainboard.
