I see, thank you for your response!

Do you mean they only put ONE 16GB ram stick and left the other slot empty? because I believe that is also my case, too. I’m asking because I wasn’t so sure if it supported up to 32 GB or 64 GB RAM. But I did further research that it does indeed support 2x32GB RAMs to support up to 64 GB RAM. (I believe when the seller said it supported up to 32GB ram, I guess they meant per RAM stick).

I will do further research for the extra NVMe’s slot, Thank you for your response!
