Thanks for the reply.
It's a shame because there are more than 200 entries for the XTU2 with i7 7700k: https://hwbot.org/benchmark/xtu_2.0/rankings?hardwareTypeId=processor_5271
But I suppose that is with and older version of the XTU2.
I already have and older version of the XTU (6.2.0.24) but I think that is too old for the XTU2, because according to the rules I need "Intel XTU 2.0 version 7.3.3 or newer"
