I was wondering which setup gives the best performance for a high-end Asus motherboard. The options are two different kits: one has four sticks of 8GB RAM total (2x4000MHz), and the other has two sticks of 16GB but at slower timings. At first, I thought getting more memory would be better. But some people said that having too many slow sticks will actually hurt things instead of help them.

If you need 32GB, just buy a single stick and don't try sticking two sticks together—that's not how it works. The best speed comes from one stick with CL15 timing, but 4000MHz is overclocking RAM, so you'll have to check if your motherboard and CPU can handle that...

If you want 32GB RAM, buy one kit that matches up instead of trying to mix two different kits together. The best performance comes from a model with CL15 timings at 4000MHz. These are "OC" (Overclocked) speeds, so you need to make sure your motherboard and CPU both support that high speed before buying. Your RAM should only come from the QVL list if they have been tested and proven to work. Even if you overclock, there is no guarantee you will get the rated frequency because the strength of the IMC (Internal Memory Controller) on the chip limits how fast it can go. If things are still confusing here, tell me your full system specs so I can help check everything.

You should probably go with Intel. AMD is too slow for those speeds if you use four sticks, because slots #1 and 3 are not the best spots anyway. You might get lucky with 2133/2400 MHz here, but that's all we can count on. The only safe way to get 32 GB of RAM at these speeds is two 16 GB sticks. There won't be any real difference between Intel and AMD in this case; the speed change comes down to nanoseconds, which is too small for programs to notice even with your eyes closed. Go with the cheaper option if you like that look. Looser timings are easier on the memory chip and less likely to cause problems with OC or XMP settings.
