version 1.4.879 required, 1.4.815 installed

I've seen a similar problem reported elsewhere for earlier SDK revisions, such as in this thread:

http://devforums.amd.com/devforum/messageview.cfm?catid=390&threadid=145590

though I didn't see a resolution.  Under 64-bit Windows 7, I've installed Catalyst 11.5 and the APP SDK 2.4, and my graphics device is an ATI Mobility Radeon HD 5470.  When I run any of the OpenCL samples, the error:

This OpenCL build requires version 1.4.879, version 1.4.815 installed.

is displayed and the GPU is not usable.  Any idea of what to try to resolve the problem?  I've uninstalled and reinstalled both the SDK and Catalyst to no avail.  Thanks in advance!

BTW, I hesitate to perform a driver clean due to this post:

http://social.technet.microsoft.com/Forums/en-US/w7itproinstall/thread/8d522f34-4b28-44b4-bdc9-9c0eb3d908f2/

The output from clinfo is as follows:

*** CAL version mismatch:
This OpenCL build requires version 1.4.879, version 1.4.815 installed.

Aborting.

More info...  Even after installing Catalyst 11.5, the driver version as reported by DeviceManager remained at 8.712.1.2000 from 4/15/2010.  Updating the driver via the Device Manager found an update and installed it with version 8.770.2.1000 from 9/19/2010.  Considering that the Catalyst 11.5 release date is 5/9/2011, this still seems like a very old driver to select. 

What driver version should Catalyst 11.5 be installing for the ATI Mobility Radeon HD 5470?  Are the driver files themselves extracted somewhere such that I can tell the Device Manager update process to use them directly?

[ With the new driver version, I am still exhibiting the same version problem as I previously reported, and even the Geeks3D GPU Caps Viewer v1.11.1 also confirms that there is no GPU OpenCL device available. ]

Thanks,

Charles

AFAIK this should be related to that the previous driver was not installed properly and you tried to upgrade that with the new 11.5 driver.

I understand your concerns mention in the thread but sadly this is the only course which can help you.

I would also like to suggest to try older SDK say 2.3. I would like to tell this is unofficial suggestion as I think the previous SDK would require less recent driver and you might get your opencl running.

Thanks

Thanks for the reply.

I hadn't presumed the original driver was installed incorrectly - it is the same one that was installed on my laptop when I purchased it, and this is the first time that I had tried to modify it.

What files/registry settings/etc. does the cleaner explicitly look for?   It would be better if I could remove files by hand to verify what actions are taken.

Actually, what specific driver file is consulted to obrtain the 1.4.815 version number?  I've viewed file properties of various driver files, but none appear to correspond.  If I could tell exactly what was out of date, that would help.

When I tried to install v2.3 of the SDK, but a dialog box appeared indicating that no supported GPU devices were found, but I could continue installation with a CPU device only.  The latest, 2.4 SDK, doesn't display that message.

Thanks,

Charles

By the way, what is the best driver cleaner to use?  It seems that the one from Guru3D is no longer available, at least according to this page:

Thanks,

well, if you dig a little deeper you will find this:

and for mobility drivers, this could maybe help you:

Thank you laobrasuca!  Ultimately, it worked. 

Longer story for posterity:

I had presumed that the one and only link on the driver list for my graphics card on the AMD web site actually contained the drivers - not so.   As per your second link, the link on the drivers page was for a file that did not have "dd" as part of its name, so it actually did not contain the graphics driver itself.  The post that you referred to provided a direct link to the correct driver file - specifically, this one:

http://www2.ati.com/drivers/mobile/11-5_mobility_vista_win7_64_dd_ccc.exe

I was not able to successfully update my driver via the Device Manager to the one contained in that file, however.  It tried to install the driver, but the installation timed out.  After the install failed, properties of the device did show the correct version number, though, even though the driver itself wasn't operational.

So, as per your first link, it was necessary to run the driver sweeper after all - Google never led me to that version, but only to the one that was no longer downloadable, so I appreciate the reference.  Windows 7 behaved oddly after reboot (hung for 45 min between clicking on my icon to log in and before it prompted for my password, prompting a hard shutdown with the power switch), but eventually I was able to log in, and the graphics device showed itself as disabled.  I then installed the driver by running the installer.  It indicated there were warnings during the install, but the log page didn't actually show any.  I was then prompted to reboot.

After rebooting, Device Manager showed my graphics card as operational, and running clinfo now showed two devices (one GPU, one CPU) for the first time ever, and GPU Caps Viewer also showed an operational GPU device for the first time. I reinstalled v2.4 of the SDK and am now able to run the samples.

Thanks again!

my pleasure! That's what the forums are mode for

Enjoy!
