Just a very important announcement: If you have broken the plastic molex around your PCIe plugs and are running cubes by plugging straight into the pins please note you are on very thin ice.
If you ever plug in a cube and miss the pins so that the top 3 pins on the Titan go into the bottom three pins on the power plug, you will instantly do the following:
1) Blow up the cube.
2) Blow up the controller
3) Blow up every other cube on the controller permanently.
This mistake basically results in a 120 amp ground loop that will flow through the lines that control the hashing engine hotel circuits. When they go from their normal 1.2 volts up to 12 volts they blow up and this is impossible to fix.
So please be careful plugging in cubes. Or just have the plugs replaced, a mistake will result in a 100% un-fixable Titan stack.
