Haig, how to identify AGP 4x boards from S/N ?

[Brama]

Is it possible to know by serial number if our G400 is the famous 4A model that is able to perform 4x AGP transfers ?

Is there any way to modify an old card not AGP 4x in a new AGP 4x capable ?

Goto Ant's news section and you'll find:

<QUOTE>When we launched G400 in May 1999, 4x motherboards did not exist. Although our part was able to work in 4x transfer mode we felt that before the Camino chip set was launched, it would be unfair to our customers to guarantee 4x operation since there are many factors that influence operation speed that are out of our control. Matrox did however ensure 4x compatibility which means that all Matrox G400 graphics boards will work seamlessly in 2x or 4x systems. Since Camino has launched, we have been able to extensively test our boards with AGP 4x. We've identified the G400 boards that support AGP 4x transfer rates with an additional '4A' in the part number: G4+MDH4A32GB/40.</QUOTE>
