Weaksauce my dude! If you want to return it and try again,
I used this one exactly (2666MHz, 16GB of course) in my Aero 15x v8 and it works great for me.Important edit: You know, your post got me thinking, and I did a little digging and it seems my RAM may be running at 2400MHz according to CPU-Z. I might need to do a little digging on which RAM is actually compatible with this thing. I definitely have 32GB of working RAM (I routinely use 25GB+ for work) but I'm not sure it's running at the speed it should be. Don't buy the thing I linked above on my recommendation.
I think your best bet is to do some review research if you are inclined to go with those options, as it seems you've been doing. Any of the names you've mentioned all seem like they would be good options.

Then you can just upgrade the RAM, it has 2 slots and only 1 is being used for 16 GB. Just put another 16 GB DDR4 RAM SODIMM in, like this stick.
