dirty ratio values for 32gb?

I've read several posts recommending that vm.dirty_ratio and vm.dirty_background_ratio should be set very low with 16gb systems. My laptop has 32gb RAM and I was wondering which values should I use for dirty_ratio (or maybe even vm.dirty_bytes/vm.dirty_background_bytes)

On my 16 GB system I only set vm.dirty_bytes/vm.dirty_background_bytes .

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Currently I have:
vm.dirty_bytes = 16777216
vm.dirty_background_bytes = 4194304

I'll try those values, thanks.
