How to select memory for motherboard when building a new machine?

I am building a new PC. What resources do I use to ensure the ram I select is compatible with the motherboard I am selecting?



Currently, this is what I know.
The motherboard accepts a type of ram, like DDR3 double sided. A front bus speed which is a maximum, like 1600MHz
E.g. ASRock B75M-DGS R2.0 - Memory Support List




The motherboard usually has a list of manufactourers of ram that is compatible. This list included module model numbers that do not completly correlate to the ram module model numbers I am looking at, as link above.



While hunting through ram, I find that the model numbers either do not match the list above at all or they match mostly.
E.g. G.Skill Sniper 8G Kit(4Gx2) DDR3 1600 F3-12800CL9D-8GBSR
However, the memory support list says: F3-12800CL9D-8GBSR2 (extra 2 on the end).



So, how do I select ram? Do I take the memory support list as gospel; What about the partial match? Or is it as simple as being a DDR3, 1600MHz.



Additional components in case they impact the question:
Intel i3 3220
ATI HD7770



When searching for this topic on the site, I only found specific instances of if a certain ram was compatible with a certain motherboard. Not a generic question such as this. Feel free to link any duplicate.
