I wouldn't bother.
What's the point of having it when it just crashes all the time.
If you bought a new tv and it kept stalling you would be straight back to the shop with it.
I installed it last night and just gave up after it crashed every 45 mins.
My pc is within recommended specs , 4gb ram quad core.
All of the recommended tweaks to OS and background services done.
X1 was fine when I upgraded from 8.5.3 to x1 expanded.
I think I will be asking for a refund and going reaper or cubase.
I don't think I have ever been happy with sonar as its workflow is just not suited for making music creatively. I have been patient, expected basic common sense changes in x1, which sort of happened, then read good things about x2 workflow improvements. However, all that just becomes insignificant when, ermm it crashes all the time.
