Blender 2.77 Cycles: branched path tracing AA samples missing

I’m using Blender 2.77 to render using Cycles. I wish to render some SSS on a candle and read that branched path tracing can help a lot with the quality. The thing is, I can’t increase my sample count more than 4. The samples do not do anything and I don’t have the AA samples there. Where is that setting?
