The infinity fabric speed, the stuff between chiplets wants to run in a 1:1 ratio with ram, so you can squeeze a little more out of that cpu if you get 3600 ram.
Ddr4 runs at half the rate is says (double data rate) so 3600 runs at 1800mhz which will match 1800mhz of the infinity fabric. Some chips can go higher but it’s not guaranteed
I used the cheapest sbc I could find at the time which was an orange pi zero to run a CUPS server
