Looks as if the DDC in general has a problem with starting, regardless of the top? Ill see how it goes and if it has problems, Ill stick the D5 back in
I think that was with the older pcb versions and weak psu's, mine certainly has no trouble starting. Got an OC Labs on mine top by the way.
This is a 3.3v pcb and a galaxy psu, so hopefully should be ok...its going to be a while before I can build it though now due to one thing and another.
