OpenCL 2.0 driver support summary?

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.

 

1) 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?

 

2) 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. amd-14.41rc1-win8.1-64bit-opencl2-sep19.exe. However, the display part of this driver is horribly unstable and crashes all the time. Other drivers I've tried are

 

amd-catalyst-15.7.1-with-dotnet45-win7-64bit.exe - Reports OpenCL 1.2

radeon-crimson-16.3.2-with-dotnet45-win7-64bit.exe - Reports OpenCL 1.2

radeon-crimson-15.11-with-dotnet45-win7-64bit.exe - Reports OpenCL 1.2

 

I've checked that the actual registered ICD DLLs are being changed by the different driver installations..... What driver should I use for OpenCL 2.0 support on an R7 260X?

 

On another machine with a R9 380 and 64 bit Windows 10 I can successfully get OpenCL 2.0 supported

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.

 

Many thanks for any help.
