cuStreamSync errors with OS X 10.8 hash

[newestofthenew]

Hi all,

I've been running ocl via the GUI app to crack an OS X 10.8 hash and I continually get a couple of different error codes as follows:

ERROR: cuStreamSynchronize() 700 Also get the numbers 715 & 716

I'm using a combination attack with the rockyou wordlist as wordlist 1 and the numbers 0-19 as wordlist 2.

I run through various combinations of settings within the app but surely enough, after 60 seconds max I get the error message.

I'm using a GeForce GT 520M, 1GB DDR3 (dedicated), 4GB (totoal available graphics) with driver version 337.88.

Can anyone suggest a solution or give me any insight if the error is "fixable"? Should I give up using the GUI and focus on using the command line?

Thanks.
