As noted in an earlier post, faster memory will not show up in more FPS (high speed memory is for "other than games"). Right now, they are showing the fastest confirmed speeds with smaller memory sizes (4GB and 8GB per stick).

I ordered 2x16GB = 32GB of 3200MHz GSkill memory. Ironically, its GSkill they are showing as one that works at a high speed. Moreover, the low cost ones I found are now "sold out". Maybe I did not shoot myself in the foot on that one

So, I see that M.2 SSD and "fast" memory (at the low price points I found) have "sold out" (at least where I looked at Newegg and Amazon). Maybe I'm not the only one starting my Ryzen build "early" (or maybe its just "chance"). Hopefully, I'll get my order in for a Ryzen 1800X in time.
