Ubuntu nVidia xorg.conf

[bughatti]

I am trying to build out a linux miner with nVidia cards and I am looking for an answer to keeping overclock settings through a reboot.  If someone has a better way, please feel free to share.  What I have done is follow this guide http://www.phoronix.com/scan.php?px=MTY1OTM&page=news_item to set coolbits 12 on all 4 of my cards in /etc/X11/xorg.conf  and use this guide to setup my virtual monitors http://unix.stackexchange.com/questions/200553/multi-nvidia-gpu-overclocking-for-computations-cuda I have the ability to OC my cards but unsure how to keep it through reboot. 


Any help would be greatly appreciated.
