SS or DS RAM for Ryzen?

Does it even matter?

You mean single channel and dual channel RAM configuration?

I think he means single sided and double sided RAM

DS is better?

if I get both around same rate, I should opt for DS. Am I correct?

Specifically for Ryzen, early on the guidance was to opt for single rank if you want the highest chances of running at higher speeds. I don't know if that is still current with all the updates since then. Early support was for 2666 single rank, 2400 dual rank.

 

Sided is not necessarily equal to ranks, which is what makes a difference. I've compared dual rank vs single rank with all other settings the same. In synthetic tests dual rank has slightly higher bandwidth but also slightly higher latency. In one specific compute application I use (similar to Prime95), dual rank gives a significant improvement to performance, but I never saw this in other apps.

 

Overall it doesn't make a huge difference so get whatever ram is cheapest, or nicer looking, or whatever.
