Question RAM speed for Ryzen 5 2600, no OC. Educate me, thanx...

Hi

I building a PC with a Ryzen 5 2600 processor. Motherboard will be micro-atx, B450, expectably MSI B450M GAMING PLUS

What I read of RAM speed confuses me. I read "higher is better, get at least 3000mhz". But I will like to learn the basics..

If i DO NOT do overclocking:
- will RAM speed in excess of 2666 never come into question, if I do not do any active overclocking?
- or can the MB and processer in standard configuration (no OC) by itself work with "boosts" that in peak can up the RAM speed?

- how do I ensure I can do "Dual channel" setup -> what are the RAM prerequisites?

For starters I do not plan to OC, and I plan to use standard box'ed cooler.
- Which frequency can I OC to with standard 2600 cooler?

- What should I choose: Single Rank or Dual Rank?

- other input is very much appriciated.
 
Ryzen can be very picky about the ram you use. Everything I've read, and in my Ryzen build i personally use G.SKILL Flare X, seems to be the most agreeable ram overall for Ryzen, for the most part, but this is based solely on things I've read and my personal build. As far as dual channel setup just follow your motherboard's instruction as to which slots your should use(usually it will specify which slots will be linked as Dual channel). As far as overclocking I will let someone more qualified to answer that.
 
The ram frequency are controlled separate from the CPU, so even if you don't OC the CPU, you can still run higher speed RAM. Ryzen is reportedly picky, but I think things are better with the 2XXX series. However, on the computer build I just did, I splurged on 3200 14-14-14 RAM. This speed is the "Samsung B-die" stuff that is supposedly very well behaved with Ryzen. I got the G-skill Trident RGB, which worked great for me.

I have an Asrock motherboard, and in my bios I simply enable "XMP" or something like that, which reads the "overclocked" data off the RAM modules and sets the timings accordingly. No need for me to mess with anything. I should probably do some benchmarking to see if the added speed even matters, but hey, the placebo effect is pretty sweet as well.

You want single rank RAM, as that can be run at higher speeds. Most of the performance stuff should be single rank.
