Even though it says 16GB of ram if you go to asus's official site https://www.asus.com/Motherboards/M5A78LMUSB3/#specifications it says 32gb. I have only installed 8GB so I can't say for sure but i'd trust the guys who made rather than the guys selling it.
Ive only installed 8gb upto now myself
16gb but i have only 8gb up to now
