My 2 rigs were running this miner just fine until I added a new card to fill out the second rig. 

Now only this rig is consistently crashing with the error:

Cuda error in func 'quark_blake512_cpu_setBlock_80' at line 701 : unspecified launch failure.                         

I've tried removing OC, lower intensity and have had no luck.  Both rigs are now at 6 cards mixing 1070TIs and 1070s.

Any ideas?

Thx!
