TechyAlex :
Is the Gigabyte GA-H110M-A using the same ddr4?
There is next to no DDR4 made specifically for any one motherboard.
As stated previously, the vast majority of Skylake motherboards are DDR4. As also pointed out by someone else, 4GB is far too little for a modern PC, so you need new RAM anyways and should simply get DDR4. (Unless you only plan to play minesweeper, basic web browsing and other trivial stuff on it.)
