which ram can I combine to my existing ram?

You can only use ram with 4GB and 1600MHz speed with that ram

can I use gskill ripjawx 8gb(8x1) ram with my ram?

You can use two different brands of ram if you have to obviously most people like to keep it matching, but if the specs between the two sticks are the same you should be okay. Just make sure they are both the same speeds or it will use the slower of the two.
