Hello ! On other thread I asked about this memory. This is answer:

I'm using 2x16GB HX426S15IB2/16 and it works fine at 2667 MHz. It's rated at CL15. However I'm not able to mix it with existing Apple RAM, it will downgrade to 2133MHz. At best it's 2400MHz when running in single channel. Looking at the other thread, it looks like you really cannot mix anything with Apple RAM regardless of the brand.
