Hi,

i have bought a Gainward 2400 6800 GT Golden Sample off Ebay. This card is guaranteed by Gainward to run stable even at Ultra settings. The owner has changed the heatsink to a Silencer 5.

So i installed the card, put Forceware 78.01 on my PC and now i am getting some weird artifacts. You can see them here http://www.photo.net/photodb/photo?photo_id=3799588 They look like some wavering red stripes all over the screen. Does anyone recognize them as coming from memory r core overclocks?

This happens in 3DMark05 demo 1 and Chronicles of Riddick from the beginning. The Nvidia 6800 and 7800 demos run fine and so is Age of Empires 3, Far Cry etc. In Half Life 2 i get those occasionally.

Once or twice the whole screen froze in 3DMark 2005.

Clocking core and memory way down (to like 200/700) has not done anything and i get core temps of around 44-47C idle and 57-60C fully loaded.

So far i cleaned the heatsink and reinstalled it with AS. The ramsinks seem to not touch the cooler properly which i have read in some reviews of this cooler, but i put some extra Arctic Silver on it to close the gaps.

I have an Asus P5B533 (AGP 4x) with p4C 2.66@3.3 with 1,5 MB RAM which ran perfectly stable before with a 9700 Pro. I have an Enermax 430 watts PSU.

Please help me, i really don't know what to do anymore :(

Heh - hate to brake it to you - but Gainward no longer has a presence in the US. You're going to have to RMA the sucker to Taiwan.

I am not from the US :)

And if somethings irreparably wrong with the card it will go back to the previous owner and not to Gainward for sure.

I was suspecting that. My guess is that he did not install the sink correctly and as such is why he was offloading it on fleabay. You seemed to have validated that after you refitted the sink.
