to use the four channel Feature, you need four Modules, which have the same number of GB. So here you can only use the two channel feature

But isn't that, when I use dual channel, I need to put same 8GB on slot 1and 3, 4GB on slot 2and 4? Science he put 8GB on slot 1and2, which means that there will be 1channel each for all 4 slots?

It is even advisable to put the Rams into the slots in that pattern, and Isn't it best practice to use the same model, speed, and throughput of memory?
