Please could you pass this to the driver team and get it fixed, please. So I'm pretty sure the DLL I've got is the correct OpenCL 2.0 DLL. Looking at the details of c:\Windows\System32\amdocl64.dll I can see the product name as "OpenCL 2.0 AMD-APP (2079.5) which is right and I can see OpenCL 2.0 entry points Which suggests it is an OpenCL 2.0 driver being loaded (I've attached the full output of clinfo for reference). Platform Version: OpenCL 2.0 AMD-APP (2079.5) I tried the latest Crimson driver (whql-win7-64bit-radeon-software-crimson-16.7.2-july19.exe) but querying the driver givesįor the device details - still only OpenCL 1.2 However, the platform is reported as Please try the below suggestions and share your observations.ġ) Please un-install the APP SDK and check the clinfo.Ģ) If still see the same, completely un-install the driver from control panel and then freshly install the driver and check the clinfo output.ģ) If nothing solved, please try above step once without the Intel platform.

For example, please find the attached clinfo files generated with Crimson 16.6.1 for both Hawaii-XT (OpenCL 2.0) and Capverde XT(OpenCL 1.2) devices. Based on the device capabilities (and also driver), those fields indicate the right values (applicable even for the OpenCL 1.2 devices). Some of the OpenCL 2.0 related fields such as SVM capabilities, device side queue etc. Your clinfo output is not the expected one. The only other info I found on the web was OpenCL 2.0 requirements changed in Crimson driver? which relates to Linux and with my 8Gb of RAM shouldn't affect me. On another machine with a R9 380 and 64 bit Windows 10 I can successfully get OpenCL 2.0 supported What driver should I use for OpenCL 2.0 support on an R7 260X? I've checked that the actual registered ICD DLLs are being changed by the different driver installations. Radeon-crimson-16.3.2-with-dotnet45-win7-64bit.exe - Reports OpenCL 1.2 Other drivers I've tried areĪmd-catalyst-15.7.1-with-dotnet45-win7-64bit.exe - Reports OpenCL 1.2 However, the display part of this driver is horribly unstable and crashes all the time. I'm trying to do some OpenCL 2.0 development on AMD GPUs and I've spent a day messing around with various drivers trying to get a stable setup with OpenCL 2.0 driver support.ġ) Is there a definitive and official list/table in the driver release notes or elsewhere that lists the supported versions of OpenCL on various AMD GPUs?Ģ) Specifically, on an R7 260X in a 64 bit Windows 7 machine with 8Gb memory RAM the only driver that provides OpenCL 2.0 is the one from AMD OpenCL™ 2.0 Driver, i.e.
