ATI Catalyst 9.12 Hotfix with OpenCL Support


ATI Catalyst display drivers

OpenCL logo



After the WHQL version, AMD release a hotfix for ATI Catalyst 9.12. This hotfix provides full support for GPU acceleration of OpenCL when used in conjunction with the ATI Stream SDK v2.0. This support of OpenCL is limited to Radeon HD 5970 Series, Radeon HD 5800 Series, Radeon HD 5700 Series, ATI Radeon HD 4000 Series and FireStream 9200 Series.

The hotfix also resolves some problems like mouse being enlarged under Windows7, performance of OpenGL games, or CrossFireX support for Eyefinity.

You can grab the 9.12 hotfix HERE.

I don’t know what AMD has done with this driver but the installation takes hours… Fortunately AMD has published this hotfix, because it’s the only way for me to have the 9.12 + HD 5870 + Vista. The 9.12 WHQL can’t detect my HD 5970. Tough life…

    Is this support (OCL) is added only with Stream SDK installed?
    I’m asking, cause i’ve installed this hotfix and there is no OCL support. At least i didn’t find any OCL files in driver package and GPU Caps Viewer reported the same.

    Yes you have to install the stream sdk beta4 to enable OpenCL with the hotfix 9.12.

    Sorry for doubleposting, but i forgot to mention, that i’m using AMD 4850 (Saphire) on Windows 7 (7100 RTM) and OGL version returned is: “3.2.9239 Compatibility Profile Context”. Also, version of a driver returned is: “Catalyst 09.12 – 8.682.2-091214a-092914E (12-14-2009)”.
    BTW, clocks didn’t show up: “__________| not available :( |__________”.

    Thanks for your feedback. Seems Catalyst does not support clock reading on some Radeon or OS…

    From my tests, OpenCL is supported on Radeon HD 4850 on all Windows.

    Thank you for replying on this.
    I’ve managed to use OpenCL on my notebook with a AMD CPU and NVidia GPU. But it worked only in CPU mode, because NVidia was only 7300GO.
    At that point i didn’t install catalyst drivers. Just Stream SDK, but had to rip off a catalyst driver to get OpenCL.dll file from there, cause it wasn’t included in Stream SDK pack by a mistake of catalyst crew.
    Hope soon we will get a workable OpenCL in GPU mode after just installing a fresh driver, without any Stream SDK stuff. I guess NVidia allready done that.
