Well, from what I can see by what is written, only one of them lists 2 x 4GB .... if the other two are 1 x *GB, then those two should not be purchased. They are all DDR4-3000 CAS 15 so if all are 2 x 4GB, its down to a) color / appearance and b) do reviews show any having a particular OC advantage, if that interests you)
Yeah, sorry, i corrected the GB amount. Only the second one is 1x8GB. Why is that worse than 2x4?
Don't know about OC advantage, don't know what to look for in it, but ill try
It isn't worse per-se, However, it can suffer a slight hit in performance due to using only one channel for RAM compared to using two sticks of RAM and two memory channels.
RAM is RAM is RAM for the most part. It really doesn't matter what you get now days, as long as it fits your needs: physical size, memory capacity, color, latency, RGB or no RGB. Just choose the cheapest that fits your board with the characteristics I mentioned that you care about and don't worry too much about the rest. Ryzen still might be a bit picky on some of the internals, but not as bad as it once was, and Intel isn't really picky that I've seen.
Not going to overclock the RAM (run it faster than its rating)? Don't worry about any overclocking advantages one might have over another, unless you're concerned with squeezing the last drop of speed out of the RAM you choose. Overclock advantage can be how one brand or model with the same ratings as another can outperform the other above its specifications.
