[SOLVED] 4x4GB 3000MHz or 2x8GB 3600MHz

Alright so in my last build (Ryzen 7 3700x + RTX 2070 Super) I had a 2x8GB kit @ 3200mhz cl16 from HyperX. It was alright but I could see that I had lower fps and less stable fps than someone with the same build that had quad channel.My question is, for my next build should I use a 4x4GB kit @3000mhz cl15 from corsair or should I go with a 2x8GB kit @3600Mhz cl18 from corsair? They're both 94£ so the price doesn't matter. I need performance and stable fps. BTW my next build will be a Ryzen 9 3900x on a x570 mobo from Aorus. So what RAM is more suitable for it?

Quad channel boards have 8 dimm slots, 4 dimm motherboards are dual channel. Ram wouldn't be the problem here albeit 3600MHz ram would improve performance a little bit compared to your 3200 ram but nothing extraordinary, not worth the hassle. 3900x wouldn't be a great deal difference either, not in terms of fps.

Might want to start checking thermals and speeds to make sure nothing is throttling with your existing system.

I believe all AM4 CPU’s only support dual channel. You would have to go threadripper for quad. FYI using 4 dimms does not mean quad channel, it’s usually 2 dimms per channel but still dual channel.

All Ryzen CPUs are dual channel only. They work optimally with two DIMMs.

Optimally includes higher ram frequency across two channels as apposed to four where frequency is decreased somewhat.

Do they work for Intel boards then? On a z390 for example?
As it shows on this video it works on a z390 board and it gives you like 15-20% more fps.

Also seen that a 4x4 kit even if it's not quad channel it helps with 0.1% lows and 1% lows a lot. I sold my old PC and I'm building a new one. And I'm getting the ryzen 9 3900x for editing as well as I'm doing media in college. Don't just need it for gaming.
