As a matter of fact when R7 1700 came out 3000Mhz was the standard and when you had luck and dual channel you could push it to 3200Mhz.
My CPU is not really good sample so I run it stock and my RAM is at 2933Mhz because it's stable, going for 3000 or 3200Mhz is not stable on my configuration.
I run 2933Mhz on RAM for years and never really had a problem with the RAM stability.
For example Elden Ring (which minimum requirements I do not meet with my CPU, well at least at launch) loads really well.
The NVMEs are limited by the slots, but I really don't have loading issues in other titles, as you can see here in these benchmarks.
