while installation i observed a message
"The display driver installed doesnt have Opencl support for AMD GPUs. If you continue with this installation you will still be able to run Opencl on compatible x86 cpus"
. I would like to know why did it show this warning in the first place. here is my system profile
OS- windows 7
ATI Stream- v2.1 (I thought of trying 2.0 i couldnt find an installer)
Graphics Chipset ATI Mobility Radeon HD 4500 Series (website says it supports opencl )
Driver:- ATI Catalyst™ Mobility 10.5 (the ati webiste said tested driver as 10.4 but again i couldnt find that driver and i am not sure if this can be an issue)
soyeed,
Just to be sure, did you check whether your notebook fall under the unsupported notebooks category given at driver download page?
ya i did...looks fine to me
Could you run CAL sample 'FindNumDevices' and CLInfo and post the results?
OUTPUT of FindNumDevices

Passed!
Either you did not uninstall the previous driver, or there are leftovers from previous installations.
Do a clean reinstall. CAL version should be 1.4.635 or later if you are using catalyst 10.5 drivers.
