I have this (#1).
#1: DRAM, DDR3 2133, 32GB (2X16GB)

I have 2 of this, so I have total 64GB. But this is DDR3 2133. So it's old I think.
I run STATA, which loads all data to RAM. So RAM speed is important. So I want to upgrade.
Last week I bought next one (#2).
#2: SDRAM, DDR4 3600, PC4 28800, 288-Pin, 64GB (2X32GB)

But later I learned that there are things with faster RAM speed (#3).
#3: SDRAM, DDR4 5000, PC4-50000, 288-Pin, 16GB (2X8GB)

Which option will be faster for a program (Stata) which loads all data to RAM and performs calculations?
Option 1: Use #2 only (4 slots, 64GB in total)
Option 2: Combine #1 (3 slots, 48GB) and #3 (2 slots, 16GB)
If I go for option 2, can I force my computer to always use the fast RAM, which is #3, as long as it does not have to use more than 16GB of RAM? If that is possible, option 2 should be faster than option 1, correct?
