Q: Which memory slot is which in the graphic

I have an odd problem with a 2010 MacBook Pro. Both memory slots have DIMMS in them, but one isn't working. When I go to About This Mac/Memory, the graphic shows the left side with 4GB and the right side as empty. Does anyone know which side of the graphic represents the bottom DIMM and which represents the top? That would allow me to know which DIMM is bad or incorrectly installed since I don't have a memory tester.

 

Many thanks!

MacBook Pro, macOS Sierra (10.12), mid-2010
