I have a 5 year old desktop PC with 2 sticks of DDR3 4GB RAM. One of the two has failed - fortunately a rare problem. So I added that 8GB of DDR3 and now I have 12GB of RAM for better performance. Because of this, I added an SSD as the "C" drive for the OS, which greatly improved performance! Tech support was very helpful with advice on my motherboard and what RAM to buy.
