ATI Radeon HD6870 problem HELP!!

[tinz]

I m using sapphire 6870 graphic card, and with 2 monitor.
if i put GraphicsEnabler=No then 2 of my monitor work , but DVD player and geekbench crash when i try to launch.
if i put it Yes. i have only 1 monitor work!! any ideas?

and in my system profiler/ graphics page, it show PCIe Lane Width: x8. is it normal? not x16???

Try a different framebuffer. x8 is not normal, should be x16.

Check my sig on info how to choose a different framebuffer.

Hey tinz, I was going through the same question last week, follow the guide in injectx's signature here

viewtopic.php?p=106030#p106030

using Andy's fix. That includes a version of chameleon that is a newer version than the ones included in multibeast (r750), it has full ATI and Sandy Bridge support.

i did exactly the 4 step. and try all different framebuffer,so that PCIe now show up x16 already!! but my display still same, 1 monitor sleep...

I've got the same problem also with a Sapphire 6870,

would be great if we could get both DVIs to run on duckweed

cheers,
