Problem with OpenCL on Mobility Radeon HD 4650

Hello,

I'm trying to install the ATI Stream SDK 2.0 on a Vista x86 SP1 using a Mobility Radeon HD 4650.

When i try to install the Stream SDK i get a warning that my display driver does not support OpenCL functionality and when trying to run the SDK samples i don't get my GPU as a supported device (only the CPU is supported).

I installed the 9.12 Hotfix but it doesen't seem to solve the issue. I'm not sure if i'm using the proper driver. I downloaded the latest graphics drivers for the GPU from the AMD support page: http://support.amd.com/us/gpudownload/Pages/index.aspx

Maybie i have the wrong drivers but i didn't manage to find any other drivers or information on how to setup the Stream SDK 2.0 with OpenCL and a Mobility Radeon HD 4650.

Is there a proper driver i can download from somewhere or there is something else that i'm missing?

I have the same problem with an HP G72a26 laptop with an AMD Mobility Radeon 5470.

I think the Radeon not showing up under OpenCL may have something to do with the laptop having switchable graphics. It switches between Intel and AMD.

Dr. Haribo,

Can you please tell, what driver and SDK you have installed in your laptop.

sorry, I am not aware how swichable graphics technology works. Can you select which graphics card to use for display purpose?
