The one in this post stream with the red background. 
listen, I apologize if I’m upsetting people here, because I don’t know everything. That’s why I’m here. 
I thought ram was as simple as match the ddr, and the speed. I have learned a lot in the past few days.

This will be my last post in this thread. Read and re-read what I said in my post above that includes the picture with the red background. I believe that is the correct 16GB stick to buy and test with if you wish. Test with 1, if confirmed to work with 1 run with 4 identical ones. Or be happy with 4 8GB sticks we know to be correct already. Don't try to mix 8GB and 16GB sticks... I'm sure DGroves would agree you need to keep things as simple as possible.

You have found that memory is a lot more complicated than you thought. Some of these computers are very picky about using the exact correct memory, and some are more forgiving. That is the way it is; these are not cheap computers nor cheap memory. You will return a favor to other forum members if you make the investment and post back on your experience. 

I'd just buy a Z440, update its BIOS, and soup it up. It has more mature technology and can be improved upon to a much greater degree and is sure less expensive to get memory/other parts for.
