Thanks for posting.
I have white-listed you, so you should be able to post your OpenCL questions directly in the OpenCL forum. I am moving this post there -- the experts there should respond.
What version of Windows do you have?
You should be able to uninstall it from Programs and Features...
Search your Intel SDK medium for any installation notes..
If everything else fails, there is always the Intel opencl group
This is a rather buggy behaviour for clinfo, that should be looked after. Since clinfo just uses opencl commands to probe environment, it is rather an SDK problem.
What SDK are you using?
The clock is nothing more than 1/20 wrong items reported.
Please check the registry here: HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenCL\Vendors
Do you see multiple vendors listed there? If so, please check whether removing/disabling the unwanted registry solves the problem or not.
