So how does it work? Non-K Skylake processors are multiplier locked and motherboard manufacturers won't be able to circumvent this. Rather they have found a way to make base clock overclocking possible with nothing more than a BIOS update.
For example, the Core i3-6100 has a base clock of 100MHz with a 37 clock multiplier, effective for its 3700MHz operating frequency.
The clock multiplier will remain locked in non-K processors, but now you will be able to increase the base clock as far as your processor will allow. In our tests with the Core i3-6100 thus far, 127MHz was the highest stable base clock we could achieve. Multiplied by 37, that's a 1GHz overclock
