[sebastienmaass]

I baught two ram modules that don't work together, one OCZ and the other kingston.

OCZ:

I was told that I can't run them together and they don't work either way so I have to choose wich to use of the two. I want and buy a second one in the near future, will any module of the same manufacturer work?

thanks for any replies!
