4x8 vs 2x16 RAM upgrade

[ineventhorizon]

Hello, I've been thinking to upgrade my memories to 32GB capacity. I've already got XPG Spectrix D41 DDR4 3200 MHz CL16 8 GB X 2 RAM installed on the build. Should I get a new pair or should I sell my current rams and get 2x16?

I'm using my memories at XMP besides that nothing is overclocked. Are there any performance issues that I might encounter? Can I enable XMP at same 3200 Mhz speed with 4 sticks of ram?

System:

CPU: i5 12400F
Motherboard: ASUS TUF Gaming B660M-E D4
RAM: XPG Spectrix D41 DDR4 3200 MHz CL16 8 GB X 2
GPU: Asus Rog Strix 3070 Ti

are all 4 sticks exact same and are they single rank or dual rank?

I'm using XPG Spectrix D41 DDR4 3200 MHz CL16 8 GB X 2 RAM and CPUZ says it is a single rank ram. I'll get the same model ram if I get a new pair.

You might not be able to run 4 sticks at the same XMP profile but slightly loosening the timings or lowering the frequency should work and the performance difference will be unnoticeable.

better do 2x16
because if you 2x8 + 2x8 even though they are same speed
chances are you might not enable xmp and have to manual oc

Is there a way to check if I can enable XMP?

Nope, you can only try it after you get the sticks

I've got one pair 8GB with C15 and 3000Mhz, can I try it out with that? Or frequencies must be the same to test the XMP?

2x16 and 4x8 have the same number of ranks, so it's going to be equally as easy/hard to get running in that setup at higher speeds.

You are the one who has to be willing to put the time and effort into manually entering these settings and getting it working if you buy RAM sticks with different default/XMP settings - if you are not willing to do so sell the RAM and buy a 2x16 kit

I would not hesitate to Mix 2x8GB pair with another 2x4GB pair of identical RAM.
16+8= 24GB

I do not see any good reason insisting for a 32GB as total.

Would there be a problem with XMP with the same kit that I'm using?

What 24GB? I didn't understand what you wrote. I already got 16gb ram with 2x8, thinking to get another pair.

I have just suggested a money-saving alternative solution.

No one can answer that - if you get two different kits of ram the XMP timings will be different, no one will know if those settings will work until you try them

Kiriakost: By it's very definition, you cannot buy identical ram in a smaller capacity. While 24GB of ram works and works fine, you're still going to the effort of matching the ram timings and manufacturer.


Corsair XMP ram has revisions for example, and a .1 difference can mean it's changed from hynix to samsung to micron, etc. That's when you tend to run into issues, the higher the speeds the more likely problems will occur.

Normally 16x2 would be better but since you already have 8x2 I'd just buy another pair.
