Optimal AMD Ryzen + Memory combos

[Bert the Derp]

Hey Forum !

 

I'm about to build my Ryzen setup with a Ryzen 5 3600. However I'm a bit lost at picking the memory. Size is clear, but not the speed for me. Now here is why:

I know that I could go either for a high speed memory that can be handeled by Ryzen 3600 and call it a day or go for a low latency, low speed memory and crank up the infinity fabric speed to reach nearly the same speed. Now, I don't know which is better. I'm not really into overclocking my CPU but I wish to have the best "out of the box" performance. Why there are sites and blogs about this that I actively read, I think this could be a good video idea. Recommend memory for all the 3rd gen. Ryzen CPUs in 2 point of views in terms of cheapest sollutions. If you are willing to OC your CPU and an "out of the box" top performance.

 

What do you think? Could this be a good video idea? Would you watch it and could it mean something new to you? 

Also, what is your recommendations for the cheapest, fastest memory for the Ryzen 3600 ?

They actually did a video on exactly this

 

The conclusion is that getting your infinity fabric as fast as possible, and timings as tight as possible (low latency) matters more than just pushing frequency as far as it will go.  Just get some 3200 or 3600 and then focus on the other things.

Yes, these questions and video ideas poped into my brain after seeing this. So the question still remains, is it still worth to get my hands on a CL12, but only 2400MHz or should I go to 3000MHz with CL16, 3200MHz with CL18 or even 3400MHz and CL19 without overclocking. All this with Ryzen 3600 because I'm 100% sure, not the same is the best for 3600 or 3800X.

What part of your question(s) did it not answer?  They look at everything I can think of.

So basically you're looking for the kit that gets the best stock performance, without having to adjust timings, etc.?  I would imagine it would be the lowest latency kit you can find since that's the goal when adjusting manually.

Exactly Sir! That is my goal. Which is performing faster for a streamer/gamer PC because that is not compared in the video. In the video 4:08 is simply confusing. So even if I go for a low latency and low speed memory, I still need to OC the infinity fabric? What gives? Also what counts as "very low latency"? CL14 is already very low or is Linus talking about CL12 and CL10?

My conclusion is: If I want to get the best stock performance, I need to get a memory with double the speed of the infinity fabric and the lowest latency possible, right?

In which case, the cheapest available for me is (assuming the infinity fabric is 1800MHz) the Patriot Viper Steel 16GB (2x8GB) DDR4 3600MHz with CL17. Everything else is just too damn expensive.

If latency is low or not is also influenced by speeds. Without looking at that video again, or other similar testing, my gut feel is:

Value first, with decent performance: Any 3000 or 3200 ram. I wouldn't go lower than 3000 if I can help it.

Value-performance: cheap 3600 kit, maybe CL18 (note 3600C18 is same latency as 3200C16)

Balanced performance: low latency 3600 kit (CL14 or lower)

Probably not worth it: anything above 3600

 

Note with a 3600C17 kit, Gear Down Mode is usually enabled and it'll run at C18. So you'll need to turn off GDM to run C17.
