DDR4 64GB Decisions | 2x32 or 4x16 | 3600Mhz C16

[JeffJK]

Hi,

My current setup:

CPU: Ryzen 9 5900X
GPU: EVGA 3080ti FTW
RAM: Corsair LPX 16GB (2x8GB) 4000MHz CL16
Mobo: Asus Prime x570 Pro/CSM

Context:

I have multiple applications running at a time on a couple monitors and notice my RAM usage is hanging around 10GB idle (with usual browser windows open in background).  When I load up a game, it hangs around 14GB.

I would sometimes alt+tab out of a game to browse or watch a video. It would then stutter for a bit.

 

So now I'm looking to upgrade my RAM.

I'm looking to get:

64GB

3600MHz

C16

 

But not sure on configuration.

Should I get: 2x32GB or 4x16GB?
 

I understand there's more strain on the Mobo if I get 4x16GB, but it's easier to find C16.
I don't think there's set of 2x32GB with C16, but there's plenty of C18.

Is there any performance difference?

My budget is around $300AUD ($200USD)

 

Right now I'm considering getting:
2x Corsair Vengeance RGB RT 32GB Kit (2x16GB) DDR4 C16 3600MHz
(so 4x 16GB).
This a good idea?

Its almost always better to go the 2x32 route rather then 4x16 if you actually want to get the speeds.

 

Most of the time on 3000/5000 series ryzen, 4 dimms are going to be running at 3200 or 3000. You seem to have a very good IMC being able to run 4000 cl16 ram.

 

Will you notice the difference between cl18 or Cl 16? More then likely not but if the tertiary timings are much worse and such then yes it becomes noticeable.

 

it is not a good idea to buy 2 2x16 kits, often times this just does not work. you may get lucky though, but its often better to buy 2x32 or a 4x16 kit.

2x32GB.

With the very little you gave us to go off of, there will be no performance difference you notice unless you do benchmarks.

2x is usually cheaper too, and better because two are more stable than 4

Definitely 2x, I have used 4 sticks on a ryzen chip on the past and even at a slower ram speed (2666) windows would still crash when anything was using more than 2 of the sticks of ram. dual channel is def worth it
