-1% utilization issue with cudahashcat

[cudanoob]

I've been looking around to see if anyone else is having the same issue as me for a while now with no success. Im running Ubuntu 12.04 with 2 geforce 9500 gts and when I run cudahashcat on a EPA my gpus are showing a -1% utilization. I checked tuner my nvidia settings and seen that one gpu is running at 20% and the other at 2%. Why is it showing -1% and only cracking at a combined speed of 3400/s? And I have also noticed that my gpu is being autotuneddown to 1.
