Gaming Pavillion15-cx0056wm will not run 32GB ram

[Mlang66235]

I tried to upgrade the RAM in my Pavillon15-cx0056wm from 8 gigs of RAM to 32 (two sticks of 16) and the laptop is not having it. I can put 1 stick of 16 gigs in and the laptop runs it fine. I tried 32 gigs because I read in the forum that it should be able to be done.  Can this even be done?

RAM sticks are NOT the same, looks like "Kingston Technology HyperX Impact 32GB 2666MHz DDR4 CL15 260-Pin SODIMM Laptop Memory, Kit of 2 (HX426S15IB2K2/32)" id not compatible.

Have you tried Unbuffered • NON-ECC RAM ? For example:
