lapping my pot and IHS helped cracking which seems strange if the crack is between die and IHS....either way its worth doing.
Also remove the glue on kaby, it hurts mhz if you dont. the glue will never be correct once the ihs is removed anyways

Or if you have an unlimited budget you could grab a Titan xp and 6950x both of which are extremely powerful. Asus x99 mobos were best IMO.
