[SOLVED] Second pair of RAMs

[Tigran97]

Hi all.
I have a pair of 8GB Crucial Ballistix Sport LT 3000 MHz CL15 DRAMs running in dual channel on my PC. I want to add two more RAM sticks on the remaining two free slots, but this model is unavailable now. Will it work properly if I put memory with other MHz or CL? Are there any requirements/restrictions?

mixing ram not in 1 kit, sometime works, sometime don't

Such combinations have no guarantee to be compatible together.

ddr4 is really picky!
