GPU: Quadro K5100M (Kepler) with driver 426.00. OS: Windows 8.1 Pro x64.
I built CUDA sample deviceQueryDrv against CUDA toolkit 8.0. I built 32-bit and 64-bit versions.
The 32-bit version runs fine. The 64-bit version fails cuInit(0) with error 999 (unknown error).
Your ideas for resolving this would be appreciated. Thank you.
