What does this note means from Gigabyte's Manual ?
When installing the memory, make sure to begin with the first socket of each channel, such as
DDR4_1_1A, DDR4_3_1B, DDR4_5_1C, and DDR4_7_1D.
I can't understand it.
I'm seeing the configuration table for 1,2,4,6,8 modules (I'm planning to install 8) but that note implies what?
That if you have power/PSU/cables OFF, you must install the modules in a certain order??
Like you can't put the one module after the other for all 8?

Doesn't make sense. Is that what it means?

Yes, you must insert the RAM in a certain order (unless you fill up all the slots the first time). There should be a picture telling you which slot is which so you can know which slots the RAM must go in so that the PC turns on.

You can ignore any order, if you're filling all the ram slots with same model/capacity ram modules.
