Mix DDR2 Dual RAM?

[Chaosboss]

Hi all,

I currently have G.Skill 4GB (2x2gb) DDR2 PQ PC2-8000C5, I have upgraded to Windows 7 & my motherboard can support 8GB.

Unfortunately I am unable to find where to buy another 2 sticks of this RAM, so am I able to add 2 sticks of different RAM?

If so, which do you advise?



Thanks in advance
