Some tips for ppl who is setting up titan
1) ribbon cables got two side, they are not the same
2) sometimes the pcie slot might be fucked up, make sure to try every single spot on the controller
3) don't forget update the firmware to 1.02
4) you are able to use more than one psu to power them ( i am using 2-3 psu for one titan)
5) firmware is kinda unstable atm, using auto-switch pool might cause a 40% drop of hash ( not sure yet )
