Which is better 4x8gb or 2x16gb

I don't know much about ram and how motherboards work when using ram. I know theres (4) slots, but I think theres dual channel and quad channel.. So I rather buy the right ram the first time them mess up and have chips not being utilized.

Upgrading RAM on my Media Server mother board is ASUS Prime-Z270-AR
https://www.asus.com/us/Motherboards/PRIME-Z270-AR/

Trying to figure you if I should get 4x8gb sticks or 2x16gb sticks.
I think the 2x16gb is the way to go.

Looking at the Ballistix Spot LT 3200mhz

I could buy one 16gb chip for now and upgrade to a second in the future, but I think ram is best in pairs?
On a bit of a buget, but if I have to buy the full 32gb now, I will.

Quad channel is reserved for X79/X99/X299/X399 everything else such as your Z270 board has dual channel only

2x16GB will be better because your CPU has dual channel memory controller. 4x8GB wont make any performance difference in it. 4x8GB is beneficial for X99 / X299 based PC, due to quad channel memory controller.

So basically, 2 sticks over 4 sticks would be better as it offers less stress and may result in a higher OC for the system and better stability. But I can have 4 x 8gb sticks and they technically could preform the same as 2x16gb in stock environments.

Stupid Question:
Is there a huge draw back to just putting in 1x16gb for now and upgrading to a second when I get the money?

But is there any draw backs to say running 1x16 over 2x8?
Like any noticeable difference?

Outside of the fact that if I start with 8gb sticks the most I can put in one system is 32gb vs 16gb sticks I can get to 64?

Buy what you can afford, don't worry about 2 vs 4.

Single channel going to be slower but how much slower depends on the work load and task

Hi,
Buy in packs
If you want 16gb sticks get a 2x16gb kit
Later you can try another 2x16 kit

Never buy one stick and expect to match it later that makes no sense
Stick with 2x8gb if the budget is that limited.

Wow that was nuts.. I mean HUGE difference in FPS.
It is also very odd that the 8gb used less GPU, but more CPU.. didnt make sense.
