OK.

Right now I have 2x512 sticks running in dual channel. (Setup: A1:512;
B1:512)

I'm thinking of getting another GB.

If I bought 1x1GB stick, will it work? I would assume I will have to forgo
dual channel, but I can accept that. (So, I was thinking: A1:1GB; A2:512;
B1:512).

Just a quick answer, thanks.

Many TIA.
