[SOLVED] Can I pair these two memories?

[aceeblue3]

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.

If it does run with your other module it will run at 2133. Mixing and adding memory is hit and miss even if identical. You won't know till you try them together.
