CUDA 8.0 RC couldn't detect GTX 1080

After I install 2 of GTX 1080 I found that they still have not support with Octane render because of CUDA.
I download CUDA 8.0RC from developer site,
I try to Install CUDA 8.0 from Nvidia’s developer forum but it doesn’t work because the CUDA installation has displayed {this graphics driver could not find compatible} ,
I send this bug report to Nvidia developer so they reply
{As noted on the CUDA 8.0 RC download page, GeForce GTX 1080 developers must re-install the latest driver from www.nvidia.com/drivers after installing any of these CUDA Toolkits.

Please install the CUDA 8.0 RC Toolkit without selected driver components, and then install latest driver version - 368.39 for Windows 10 64-bit/GTX 1080, it’s compatible with the CUDA 8.0 RC Toolkit as well. Thanks.}
I follow their steps but the result still same.

Could you help me to resolve this problem,

Thanks

follow the instructions in the install guide and state what the results were of the verification tests after installing CUDA 8RC.

I’m new to compiling CUDA samples, so forgive me if I miss something.

I am having the same issue as degreebeat. I have a GTX 1080 that is seemingly not working with CUDA 8.0 RC
CUDA 8.0 RC installation cannot find a compatible device.
I installed without the selected driver components and installed the latest driver (368.39 for Win10).

I’ve run the deviceQuery and deviceQueryDrv Samples. I tried to build the bandwidthTest Sample, however I get an error in MS Visual Studio 2015 that states: Microsoft Visual Studio 2015 Update >= 2 is not supported yet!

Here are the results from deviceQuery & deviceQueryDrv:

Thanks in advance for any help.

unfortunately, CUDA 8.0RC supports VS2015 Update1 or earlier.

Any chance of seeing an update within the foreseeable future?
Is that something we will have to wait until the CUDA 8.0 launch for?
