I currently have a Kingston ddr4 2133mhz KHX2133C14D4/4G and looking to install another 4gb. I wanna know if it will work with Kingston ddr4 2400mhz HX424C15FB/4 ?? Also my motherboard supports max 2133mhz.
Yes. It will run at 2133 MHz instead. Although why not buy the same memory kit? Usually faster memory is more expensive. (Just my take )
