[SOLVED] RAM 2x4gb + 1x8gb?

[cadelele12]

Hello everyone, I already have a 2x4gb RAM set, and my MOBO can get up to 4 slots. I'm in the need to upgrade ram, 8gb is being low for me.
Sadly, in my country RAM is expensive as gold, so can I buy just a 8gb ram stick to add to my 2x4gb?
Or I'll need to dump away my 4gig sticks in order to keep "expandable" with my 8gb stick.
Maybe 4x4gb should be enought? (DDR3)

Adding or mixing ram is hit and miss even if identical.

So what would be my best option?

A new 2x8 set is the best option if supported by the board.
