Mixing RAM with different CL and it doesn't work

Hello, I've read a lot of posts about mixing 2 RAM sticks with the same frequency (DDR3 1600 MHz) but different CLs. One is CL11 and the other CL10. When I start my pc up and go into BIOS it doesn't even recognize there's another RAM stick in there.

-1st stick (original I got when buying the computer) - Crucial CT102464BA160B 8GB DDR3 1600 MHz CL11
-2nd stick - Kingston HyperX Fury 8 GB DDR3 1600 MHz CL10

Any help is appreciated, I'm clueless. Thanks in advance :D

P.S. the new one works separately if it helps in any way.

Sometimes RAM modules don't mix well. If you could manually configure the settings for the crucial stick of ram to match the Kingston, you might have a better chance of working, but sometimes when you mix different ram, it simply doesn't work.

I actually just managed to match Kingston with crucial, read it's safer to match it on a higher CL value (in this case, 11), but now they're working on 800 MHz, if CPU-z is to be trusted. Idk if that's normal or if they should work on 1600?
