Dual Channel with non dual channel memory

[futuroadjunto]

I have 2 slot of memory with non dual channel memory, and i want to buy for the other 2 slots a dual channel memory.
Is there any problem with that, mixing the 2 types of memory?

There's no such thing as "dual-channel RAM". Those "dual-channel" kits are merely matched (tested together) sticks. Your problem with mixing different types/brands will be finding some with identical, or nearly identical, timings and voltage requirements.

Now i have 512 MB, if i buy 1 GB dual Channe, it will work in dual channel the 1 GB that i buy?

Mixing memory is never a good idea. I would suggest a 2 x 1gb kit.
