Thank you for reply, ryork. I know v10.1 works fine in your environment.
The result of deviceQuery.exe in case of succeeded with Toolkit v10.0 in my environment is follows.

deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 10.0, CUDA Runtime Version = 10.0, NumDevs = 1
Result = PASS
By the way, I peformed some experiments with the combination of runtime library and driver, and I think the problem might be in driver version 425.25 or later from following result.
- cudart64_100.dll (v10.0) x driver 411.31 (v10.0) -> cudaGetDeviceProperty() returns 0.
- cudart64_100.dll (v10.0) x driver 425.25 (v10.1) -> cudaGetDeviceProperty() returns 0 or 30 (defined as cudaErrorUnknown in v10.0)
- cudart64_101.dll (v10.1) x driver 425.25 (v10.1) -> cudaGetDeviceProperty() returns 0 or 999 (defiend as cudaErrorUnknown in v10.1)
- cudart64_101.dll (v10.1) x driver 425.31 (Game Ready Driver) -> cudaGetDeviceProperty() returns 0 or 999 (defiend as cudaErrorUnknown in v10.1)
Please let me know if anyone have additional information or notices.
