Nvidia 970M issue

I'm trying to do a benchmark on my new laptop i7-4720HQ with Nvidia 970M 3Gb.  I am running cudahashcat 1.37 and the newest Nvidia drivers (358.50) on Windows 7 Pro 64.

I have tried cudaHashCat32 -b and cudaHashcat64 -b    Both runs get thru about 5 tests and are showing fantastic speed but both blow up with a ccStreamSynchronize() 999 ERROR.

I have tried rolling the Nvidia drivers back several versions but no change.  I also googled the error and read the wiki.  Any ideas on what could be wrong would be appreciated.
