------- IMPORTANT Cube Prep ----------It is imperative that you perform the following tasks upon receipt of your cube as some shifting has likely occurred during shipping from China.
1) Open the unit up and tighten the 4 heatsink screws on each blade. If there's a loose screw inside of the case, odds are it's missing from a heatsink. Don't ignore loose screws or throw them away!
2) Line the blades up in the upper rails of the case.
Notes:
When putting the cube back together, make sure to guide the red status led into the small hole on the fan side faceplate. If disregarded, it could possibly bend back and break off.
When tuning your cube,
do not hit the browser refresh button after changing clock speed. The unit will cycle back and forth between clock speeds with each refresh of the SW_CLOCK page. Instead, use the UI's refresh button located at the bottom left of the screen.
Suggestions:
BFGMiner is a great application for running multiple cubes in one easy interface. However, I have found that it comes with a slight decrease in performance on cubes and Blades. If you are not seeing your cubes performing to their full potential, I suggest trying Slush's stratum proxy:

Setup Guide:I highly recommend Dogie's Comprehensive ASICMiner Cube Setup guide
