When i installed my awesume Ultra II Had to do some things that were diffirent. At first it would not reconise it so went to disk mangement to for mat. I am runnig win 7 pro with 6 gig mem & 5200 cpu. I used Pargon for my migation software. It worked great! I also used a write up on PC Advisor (How to make a new SSD your C:drive) Worked great after that.
