I basically have a CPU, Mobo ( with onboard graphics ), power supply, HDD, but I don't have RAM.
I tested everything I have and they work in perfect condition. Though I have no idea if the CPU works or not. Any help will be appreciated, thanks!

Alright, which RAM is compatible with my mobo then? ( Gigabyte GA-MA78GM-US2H (rev. 1.0))
I know it is a DIMM socket, but how many pins does it have?
