G. Skill Flare X 32Gb (4x8Gb) DDR4-2400 C15 or G.Skill TridentZ RGB 16Gb (2x8Gb) DDR4 3200 C14?

I'm about to upgrade my pc with amd ryzen 5 2600 and msi tomahawk B450 and i need some opinions about ram sticks. Thank you in advance!!

Unless you have a very specific need for 32gb the second kit will be much much better with ryzen

Faster RAM equals more powerful CPU when it comes to Ryzen.

if you could go with flare x cas 14 for a dual set of 8 gig each module on the 3200 tab https://www.gskill.com/en/configurator?manu=55&chip=3396&model=3441

So im guessing that flare x are samsung b-die and amd compatible also i think that they are dual rank so they wont lack so much speed and i will have for the same price another 16gb wont i? Thank you for ur responses.

check my specs use a 350 board with them and yes they are samsung b-die on cas 14 .

If you use 4 sticks of memory you'll likely lose speed as ryzen rarely works well with more than 2

According to what? According to this video, quad channel gets about 10-20 higher FPS.

this video is on threadripper and not the cpu it use .

There's no such thing as quad channel on ryzen or the Intel regular desktop parts. It's all dual channel additing 4 sticks usually results in you not being able to to run the ram above 2933

Depends on what purpose. If you are into running VM's and production work, the 32Gb will be far better overall than the 16Gb, no matter the speed differences to Ryzen. If for gaming, then Ryzens love faster ram, they make far better use of it than Intel as it goes hand in hand with thread bandwidth. So in that case, the 16Gb of 3200 can show upto @20% better fps than the 32Gb of 2400.

Even running high ram usage games with 2080ti sli at 4k will barely see total ram usage beyond 12Gb, so 16Gb is more than enough for any gaming orientated pc.

There's only 1 way to see quad channel usage, and thats on a mobo capable of running quad channel. That means TR4 or x99/299 type enthusiast boards with 8 ram slots. Any consumer class mobo using Ryzen or Intel with only 2-4 ram slots only has dual channel capability.

And 1 specific video on 1 specific test doesn't cover all the results. There's plenty of other tests/reviews that show for the most part there's no difference between dual and quad channel performance, the only benefit to quad channel being double the bandwidth. If you can't saturate the bandwidth of regular dual channel, any excess size is moot and not used.
