Your conclusion is wrong.A detailed gaming benchmark with RAM analysis (numbers of kits, SS or DS, etc...).
His conclusion is that 4 kits perform better than 2 sticks globally in games (for Ryzen 5000).
Of course, I assume that 4 kits is more difficult to overclock, especially in case of weak IMC:
Correction: 4 ranks is better than 2 ranks.
2 sticks with double ranks provides the same performance that 4 sticks with single ranks.
