Ok, I am buying a new Ryzen 7 1700 CPU next week with an Asrock AB350 Pro4 mobo. I want to buy good and fast ram which is the way to go for Ryzen. This ram here HX426C16FBK2 is the one I really want but they don't sell it here and the closest to these numbers is this HX426C15FB which I can buy in single 8GB sticks but they are missing this K that I have no clue of what it represents. I also have this one HX426C15FBK2/8 which is the same as the first one, the one I really want but here it comes only as an 8GB KIT and I don't think I will be able to hit 2666 of this dual rank kit if I use all 4 RAM slots. I am really sorry for making this post confusing with all these numbers but can you explain me what the K at the end means as well as other numbers (I am aware of the latency rating) and suggest some ram, even single channel if you had good experience with it on this board that doesn't seem to support really fast ram, but it could be that all the reviews are old at this point since most are 1/2 months old and bios updates are frequent. Thank you a lot in advance!!!

You don't need a Flare X kit, but the Samsung B-die DRAM chips apparently are the best for a Ryzen build. According to http://www.hw4all.com/test-review-g-skill-flare-x-memory/ you can't be sure that your Ryzen CPU will run them at 3200 MHz.

No but as I said, on that mobo I didn't see anybody get high frequency which means dual channel is the way to go. Can you suggest me some ram? Just please don't say flare X, that thing would cost me an arm and a leg
