Dual channel or Single channel memory for RYZEN?

Yeah, typically, it doesn't tend to make much of a difference in most games, particularly when the game is limited more by the GPU's performance than by the CPU. I did find an interesting video comparing Ryzen performance in single and dual channel modes though, and at two different RAM speeds...

The video shows that a dual channel memory configuration can make more of a difference in a CPU-limited scenario. When the games were run on low settings at 720p with an RX 470, there was a notable difference in framerates between the two modes, although the framerates were high enough in most cases that it wouldn't really make a practical difference, especially if you only have a 60Hz...

yes thats my question. my motherboard will have 2 slots so should i get dual channel right now for good performance or only 1 stick so later I can upgrade to 16gb. but tbh i dont need 16gb because i would only play games like league of legends , overwatch and cs go

When the games were run on low settings at 720p with an RX 470, there was a notable difference in framerates between the two modes, although the framerates were high enough in most cases that it wouldn't really make a practical difference, especially if you only have a 60Hz screen. At 1080p and high settings, most of the games were GPU limited, and dual channel made almost no difference in most cases. You could of course see a similar kind of performance difference at 1080p high with a sufficiently powerful graphics card though, perhaps with something like a GTX 1080 or RX Vega, but again, you would likely need a 144Hz screen to actually see those differences in most cases.

Personally, I would just look for a motherboard with 4 ram slots if at all possible, to get that bit of extra performance, while still having room for a simple memory upgrade in the future. We will likely see more games benefiting from having more than 8GB of RAM within the next couple years, so you'll probably want to upgrade eventually.
