The setchip depends on the game you are using. You either have the game type/variation/denom wrong, or the setchip is the wrong type. You really need to know all those parameters before you perform a clear so you can set it back up. What options did you select in the setchip menu? Maybe someone else with the game will chime in. I don't have any MK6 experience, only MKII and MKIII. All these games require specific game type, variation, denom (multidenom or single denom) in order to be sucessfully cleared and setup. The setchip version is also dependent on the game version and OS. All this information is usually found on the PAR sheet for your specific game. Getting the PAR sheet, though can be difficult. But I'm speculating that a popular game like whales of cash, would be available somewhere. Do you know your game id version?
