I already have stock 4gb 1333 mhz DDR3 RAM installed. But I feel like I need 8GB, because it is always being 75 percent or more used, often more than 85.
The problem is, I can't find that exact same type to put in the second slot.
So my question is, which 4GB ram stick can I put inside?
I live in Europe, so I would like to order something from Europe or China, not USA.
EDIT: I use 64bit Windows 10 in my Compaq CQ2951EC Desktop which has the HP 2AE2 motherboard.
