Why is only half of my RAM Usable?

Hey guys, I currently am using G.SKILL [Performance] F3-10666CL9D-4GBNQ 4gb RAM And Windows says that only 2gb are usable?
Thanks

with windows 32 bit most ram is 3.2g then if your using onboard video then some of the system ram is used as video ram.

Is your operating system 32-bit or 64-bit? What are the specs of your PC?

did you properly setup the ram in bios? Sometimes without the proper voltage and such, or if you are overclocking, all the memory will fail to post.

you need to set them to the factory specs if your bios has the options

Funnily enough i actually fixed it by flipping the ram into opposite slots haha.
Thanks all for the help though!
