6600 LE instead of GT !? PLZ help

So I just changed my graphic card. From 9800 pro to 6600 GT.
It is a Gainward 6600GT 256mb on AGP.
I installed the card. Everything runs ok. It has 8 pipelines, the clocks are
2D: 300/900
3D: 500/900

But when i install the drivers it everywhere says 6600 LE !? In display properties, rivatuner, everest 3Dmark 05, everywhere.
But when I start my computer the first screen says 6600GT vbios and so on...

Can someone help me to fix this annoyance?

Oh and the benchmarks are all on 6600 GT level.
I allready reinstalled and tried diferent drivers.
