Hi all, I'm planning to upgrade my windows into windows 7...and obviously I'm looking into more ram as well (desktop pc anyways). But when I open my pc, I found (totally forget about it) out that I only have a mother board with 2 slots for DDR2 ram; each at 1GB.

I know it might be pointless, but is there anyway to have more than 4GB ram with 2 slots? Other than buying a new mother board...At the way I am looking, I can only fit two 2GB DDR2 rams and that's it...

Or is there a single 4GB DDR2 ram available...
