It does not matter if you want to overclock your Skylake-X (or Kaby Lake-X) just a little bit or shoot for the moon with exotic cooling, ASRock's X299 OC Formula is packed to the gills with features that will help you along the way. It even has preset BIOS profiles based on settings used by renowned overclocker Nick Shih.

Overclocking performance relies on too many parts—CPU, memory, capacitors, and so forth. In that regard, preset profiles are not a guarantee hitting a certain speed.
