It's assuring to see that (for AMD) the very best is only 1.9% uplift over the basic 3,200 MHz @ 16-18-18-38. No need to spend more money there.

Now, let's do quad-rank instead of dual rank: ...
That review has nothing to do with ranks but with number of sticks in dual channel.
 
Now, let's do quad-rank instead of dual rank:
They sort of did. Today's 2x16GB kits are typically going to provide four ranks, while the 2x8GB kits will typically provide two. That's why all of the 2x16GB kits outperformed the 2x8GB kits, with the possible exception of that one DDR4-5100 kit that managed to hold it's own against a few of them in the AMD test system. But at $900, that 5100 kit is kind of nonsensical considering it was still outperformed by some 2x16GB kits of DDR4-3600 at a fraction of the price. Going with 32GB for four ranks (whether 2x16GB or 4x8GB) will tend to benefit performance more than paying a big premium for just 16GB of enthusiast-level RAM, and if one is planning to keep their system around for a number of years, the added capacity will likely provide even more benefit down the line.

Tom's had an article pointing this out shortly after the Ryzen 3000 series launched...

Yes, this article basically reinforces what we already know, spending money on expensive ram doesnt make any sense, unless you have unlimited budget.

Yes, someone has also pointed out that 4 ranks of ram is faster than 2. But, the gains are very small as well. You are better off using the budget for more cores or faster gpu.
