My laptop motherboard supports a maximum RAM speed of 3000MHz. I found some deals online for RAM sticks which have a max speed of 2933mhz. I read that 2933mhz is the speed that AMD mobos use but mine is an Intel chipset. If I buy 2933mhz RAM sticks, will my motherboard run them at 2933mhz or will it downgrade to the next level down in speed (Or just not use XMP at all)?
