TLDR: Any ccminer alternatives for windows/nvidia?

Hi.  My 6-GPU nvidia rig is constantly freezing up when trying to mine bitcore.  I've adjusted intensities and clocks are default. 

Are there any ccminer alternatives or resolutions to multi-gpu nvidia rigs freezing up?  Oh, and I can't afford .05 btc ($600++) for custom mining software. 

Thx
