It's that because of the way Ryzen cpu's are designed, it is just more difficult for that system to run 4 sticks of RAM at higher than default speeds. It's not a matter of if Ryzen can run a kit of 4 sticks of ram becuase they can at default speeds. That's an example of an Intel system that can have issues running a kit of 4 RAM sticks at higher than default speeds. While it was quite a bit cheaper to go with 4x4Gb, I could NEVER get the 4x4 kit of ram to go higher than default on speed, which was something like 1033, memory was just unstable any higher. That system I said I went with 4x4Gb sticks? it was a 2600k on a z77 mobo. I fully admit that I'm being a prima donna by wanting to populate all 4 slots for appearance. On the AMD side I don't quite get why you are essentially penalized (potentially) for populating all 4 slots. I fully understand the budget factor, my current build (2600K) has (4) 4GB sticks as it was cheaper than 2x8.
