I would go with any of the Gskills. Don't use LPX with Ryzens.

Why is that?

Why is that?

Plenty of people have complained about memory/CPU issues while pairing Corsair LPX memory with any Ryzen, I wouldn't recommend it just to be on the safe side.

but overall what is better?
3200Mhz with 16CL
or 3600Mhz with 18CL?

3200 MHz with 16CL. Not much difference between 3200 and 3600. 18CL is not preferrable for Ryzens.

CAS 18 at DDR4-3600 works out to be the same latency as CAS 16 at DDR4-3200, only with 3600 you are getting more bandwidth and a higher infinity fabric speed.

That's because the CAS number is referring to the number of cycles, but at the higher speed, each cycle equals less time.

(16 / 3200) x 1000 x 2 = 10ns
(18 / 3600) x 1000 x 2 = 10ns

From looking at the Qvl of your mobo If I was buying I would look at these. All 3 set are on your Qvl and have the Best timings.
The flare X is 3200 cl14 14 14 34 which is very close in performance to 3600 and are Samsung B-die.
My son's Msi B450 pro carbon / 3600 is running that ram fine.

The other 2 are 3600 cl16 16 16 16 36 they have the same timings as my 3600 Royal Gold set which is also Samsung B-die.
RipJaws non rgb
Trident Z rgb
All those listed have Great price's on them currently.

I can only get F4-3200C16D-16GVKB

 

[Crosslhs82x2]

From looking at the qvl that set is on it with timings of 16 18 18 38.

what is that mean?

I can't speak to whether you'd have problems with Corsair ram but I've watched enough comparison videos to safely say that a lower cas latency of 2 is not enough to beat a 400mhz increase in frequency so the Corsair 3600 would probably yield a few extra fps in games. If you are going to choose between the 2 G.Skill rams. The Ripjaw series has a heat sync the Ageas does not so if you are thinking of overclocking and the price is the same or similar I'd go with the Ripjaw.

 

[Crosslhs82x2]

That the kit
F4-3200C16D-16GVKB with ram timings of 16 18 18 38 is on the qvl of you mobo.

according to those lines (in bold) it looks like they are the same, isn't?

 

[bfollett]

From a pure cas latency calculation standpoint they look the same but there are plenty of youtube videos showing you do get some extra fps from many games with the 3600 ram. Linked below is one that specifically tests 3200 cl16 vs 3600 cl18. There are several more testing 3200 cl14 vs 3600 cl16 with the same basic result:
