Kleinman and Straguzzi suggest:
3♣: 7-8 or 11-12. 3♦ by opener asks which.
3♦: 9-10.

I can't see the point of this. With hearts trumps I play
3♣ = 7-10; 3♦ asks
3♦ = 11-12
and it achieves the same thing, but with the advantages of not having to remember a split range, the ask is bid less often, and a stronger 3♦ reply facilitates a cheap cue from opener when he is very strong. With a possibly strong 3♣ you are higher by the time the strength is confirmed.

What is the benefit of splitting range?

Chthonic found it easier to remember.

I think you want to reduce the times you ask with 3♦, and 7-8/11-12 is the worst for that. I like:
3♣ = 9-12; 3♦ asks
3♦ = 7-8

With my wife we played 3♦ as split, 7-8 or 15+ with 5+ support.
