My X1900Gt Stuck At 2D speed

[gohcj99]

Well more core supposed to running at 575 when running 3D apps but it stuck at 2D(499) when I'm running 3D apps....I'm kinda new to Ati tool so can anyone help ?

Download and run GPU-z, that should read your 3D clocks if I recall correctly. ATI Tool can be set to not read 2D clocks in properties. Let me know what GPU-z finds for you, but I bet you're card is switching just fine.

What version of catalyst are you using?

Also, you can go into CCC Overdrive, and check the GPU/Clock Requested speeds, those should be your 3D clock speeds...you should not have to enable Overdrive to see those readings.

Hope that helps! :toast:

Well,I think Ati Tool Cause my card not to switch from 2d to 3d mode....when I uninstalled it everything's back to normal..
