QVL is a list made by manufacturers so you can see what memory is compatible with what board. They dont all work together! It stands for
Qualified
Vendors
List. You need to have a look on Gigabyte's QVL for your motherboard and see if it list's the memory you have got. You can also check on Kingston's website for the memory and see if the motherboatrd is listed against it.
Memory does mean RAM, yes.
Mamory is something totally different by the way
