During game play screen becomes full of black dots/squares and lines. I do not know if this is called pixalatating. My graphics card set up is 2 Sapphire Ultimate x1950 pro 256meg in crossfire mode when the problem occurs. It happens no matter what settings I set the quality to within CCC. I have played with each card in a single setup and the problem does not exist in that mode for either card but its a bit choppy and lesser quality. Temps shown in CCC are 52 to 58.

Test results from 3D marks were odd as well; first run 6045 with crossfire enabled (balanced settings), second run 4850 single card (balanced settings) and the third run 888 with crossfire re-enabled (high-quality settings). All runs were done one right after another yesterday. Today I ran 3D Marks with crossfire enabled score and settings were 6430 balanced, 4432 optimal quality and 5501 optimal performance and crossfire enabled (all run in this order one after another).

Corruption also happens with BF 2142 but NO corruption playing Serious Sam II.

Any thoughts??? ATI and Sapphire have not been much help but kudos to them from responding with in a day.

your specs looks good and your not over heating, all the drivers updated? AMD does have a history of bottle necking,try updating the AMD driver ? :beer::deal:

thanks cdogmn Unfortunately I have all the updates, I zeroed the hard drives and reinstalled everything fresh hoping to resolve a driver or bios issue but no luck there.

UPDATE I have tried a new 3D settings in the advanced 3D section of CCC that appear to work.

1. anti-alising and anisotropic filtering set to application controled 2. adaptive anti-alising = disabled 3. catalyst A.I. = disabled 4. Mipmap detail level = high quality 5. Wait for vertical refresh = off, unless application specifies 6. Direct 3D Settings = enabled support for DXT texture formats 7 OpenGL settings = nothing enabled
