When you run with 64-bit Java, are you also using the 64-bit version of the JOCL native libraries? Not sure if this could be the problem though... normally mismatched library architectures causes a library loading error.

I've tested JOCL with 64-bit Java on Windows 10 64-bit with an nvidia graphics card, but mine is not as new as yours :)But it can't be completely broken at least.

You could try running the JOCL "info" demo that dumps information about your drivers and devices. The code is at https://github.com/JogAmp/jocl-demos, it's pretty easy to clone and build. This might give us more information about what's going on.
