My graphics card is ATI Radeon HD 545v. I have tried both Catalyst 13.4 and 12.10. The software versions are all 64 bit (except miners).

After installing SDK 2.8, guiminer exits when I run it. Before installation it shows a window:

> No OpenCL devices were found.  
> If you only want to mine using CPU or CUDA, you can ignore this message.  
> If you want to mine on ATI graphics cards, you may need to install the ATI Stream SDK, or your GPU may not support OpenCL.

Under Linux you will need to install:

* AMD Drivers
* AMD SDK
* AMD ADL

I suggest using the following link as a guide, it has all the steps in detail.

Assuming you are using windows:

Do not install (uninstall) APP SDK.
