My motherboard has 4 slots for memory (RAM). 2 Blue and 2Brown.
My two blue slots are filled with 2x512mb and now i will replace them with the 2x1gb im getting.. The question is... Can i use all for 4 (the same 2 on the blue colour and the other same 2 on the brown colour) even though the two pairs are of differnt brand and different speed? Or do all four of them have to by the exact same? Also why are the two blue and the other two brown?
Here is a photo of my motherboard (you can see the RAM slots)
