So I've chosen a Gigabyte GA-Z170X-Gaming 3 ATX LGA1151 Motherboard with compatible ram being, DDR4-2133 / 2400 / 2800 / 3000 / 3200, but my ram of choice is corsair vengence led ram with 2666mhz, im confused because on pcpartpicker, it says that it is compatible, even though the numbers dont match up, any explanations?
