How to understand that the RAM is dual-channel?

Question

RAM

I could not find the modules in the kit, but there are a lot of one each .
For example
https://www.dns-shop.ru/product/e3bd65ecdc93d763/o
... such, will they work in dual-channel mode or not?
Now there are 2 to 8 cpu-z does not show that there is a DUAL mode, I also did not find the settings in Bios to enable this mode.
As I understand it, it is enabled by default and it all depends only on the RAM itself?

Answer 1

It depends on the BIOS, motherboard and CPU
Just take 2 of the same

Answer 2

If there is no kit, then it is advisable to take at least one batch.
