Bought refurbished Dell Optiplex 330 with intel pentium dual CPU E2160 with 32 bits . Windows 10 home 64 bit was installed as an upgrade Problem: there is still only 4G RAM installed and this is not working so good with photoshop elements 2018. Original RAM capacity was 4G. Question: Since I now have 64 bit system can I install more memory say 8 or 16G Will the rest of the old computer support this and if so what would you suggest? Are the memory cards fairly universal or " case specific" ? I did add RAM to a different desktop years ago so I can do the labor. When I look up RAM for the Dell model I only find 1 and 2G available since that was the original max capacity
