Graphics 4-8 pipelines=artifact (9500NP)

When I try to open the last 4 pipelines on my shappire radeon 9500NP
I have tryed to clock it down a little, but it's the same...

anyone know what the prob. coud be?

 

They where closed for a reasion. You opened them and the card is not working properly becuase its using the broken pipes. You need to close them but i am unaware of how to do that.

 

down towards the bottom of this page, I explain why you're seeing artefacts;
