Will RAM performance drop?

Question

RAM

Hello.

I want to buy ddr4 ram.
I ’ll definitely take 16 GB
There will be 2 bars of 8 each, so that the dual-channel mode is

But I want to add another 8 GB (up to 24 GB)

Which option is better:
1) 8 + 8 and 4 + 4
2) 8 + 8 and 8

?

Will efficiency, speed, performance suffer from the fact that not all bars are of the same volume?

Answer 1

Better or 2 or 4 planks
Respectively 1st option

Answer 2

It's actually worth reading the manual. Because there may be requirements for modules that are correctly defined and support full functionality.
