<P><FONT SIZE=2>Simon,</FONT>

<P><FONT SIZE=2>The G400 does not support AGP 4x - that is the reason why. It is a 1x card - released before the 2x spec came out (hence the 2x compatible - i.e. it will work in 2x boards at 1x)</FONT></P>
<P><FONT SIZE=2>Check on the Matrox Users forum for more details - www.matroxusers.com</FONT>
</P>
<P><FONT SIZE=2>Hope that helps,</FONT>
