I have a motherboard that support dual channel memory architecture and it has 4 dimm slots? What does this mean? is it ok to buy 4 pcs or ram to achieve a total of let say...32gb? or just 2 pcs of 16gb of ram to achieve 32gb because its dual channel memory architecture?

Pleas explain it to me because its so confusing. Is it safe to say that when you have two dimm slots it will be called single channel, 4 dimms slots is dual channel and 8 slots is quad channel? Am i right?
 
Solution

Since your MoBo only supports dual channel and 2 sticks per channel, your RAM will run only in dual channel.

Here's how it works on MoBos with 4 RAM slots (i'll take my MSI Z170A Gaming M5 as an example).
Channels on my MoBo are as follows:
Slot #1 - Channel A
Slot #2 - Channel A
Slot #3 - Channel B
Slot #4 - Channel B

Currently, i have 2 sticks or RAM and they are seated in slot #1 and #3. This way, i have dual channel RAM since both sticks are in separate channel.
But if i were to put my 2 RAM sticks into slot #1 and #2, i have single channel, despite i...

I replied to your PM and wrote the solution there.

For others who might have the same issue, here's the solution:
1st, go to your MoBo specs page, link: https://www.asus.com/Motherboards/ROG-MAXIMUS-VIII-FORMULA/

2nd, from the right top selection, select the "Support" link. You should be redirected here: https://www.asus.com/Motherboards/ROG-MAXIMUS-VIII-FORMULA/HelpDesk/

3rd, once there, select the "Memory/Device Support" tab.

4th, you should see list of different files. Look for the one called "MAXIMUS VIII FORMULA Memory Report." It should be 2nd from the top.

5th, click on the "Global" link to either download it to your PC or view it online. Direct link: http://dlcdnet.asus.com/pub/ASUS/mb/LGA1151/MAXIMUS_VIII_FORMULA/M8F_DRAM_QVL_20160411.pdf
