<BR><FONT SIZE=2>Sorry Mike - got my 1x, 2x and 4x mixed up - the original G400 was labelled as 1x, 2x and 4x compatible - however when they released it 4x motherboards were not available. If you check the matrox forums way back when they came out, you will see that it can sustain up to 2x AGP bus speeds, but not 4x (but will work in a mobo supporting the 4x interface if the specs didn't change in the meantime, which I believe they didn't) It cannot run at 4x - ever.</FONT></P>

<BR><FONT SIZE=2>All G400 flavours - OEM, Bulk, Retail, SH, DH, Max all run 2x transactions. They will also run in 4x mobo but not in 4x transactions, only 2x transactions.</FONT></P>
<P><FONT SIZE=2>All I'm saying is that it is not possible for us to claim that our cards will run 4x transactions when nothing is even specified yet.</FONT></P>
