Ok guys, I worked like this.

- raise voltage up to 1.162/1.15 with ATI OV
- raise vGPU up to 1.262 with Afterburner
- close Afterburner
- raise clocks up to 1000/1200 with CCC
- raise fan up to 100% with CCC
- close CCC
- open Afterburner again and set fan to 100% (otherwise it goes down after a while).
- bench

No, in order to get 1025MHz core (past CCC limits), you set 1.29v in Afterburner, and after you close CCC you have to open AMD GPU Clock Tool and set the clocks there, then open Afterburner and set the fan to 100%). How does this itsy bitsy Vantage score look? Damn I need some LN2 for the CPU and VGA :p
