hey all, i've currently got 5gb of RAM in my mac mini and i want to take out that 1gb and put in a 4gb stick. i asked for the same RAM i bought last time but the store clerk said he wasn't sure if it was the right RAM and told me not to open it unless i'm positive it's the right type because i can't return it once it's open. on the box it says this: "KVR1333D3S9 4GB PC3 10600 CL9 204 - PINSODIMM" is this the right RAM? i'm pretty sure it is, but i just wanted to make sure. thanks!
